- Adds FK from `aibridge_interceptions.initiator_id` to `users.id`
- This is enforced by deleting any rows that don't have any users. Since
this is an experimental feature AND coder never deletes user rows I
think this is acceptable.
- Adds `name` as a property on `codersdk.MinimalUser`
- This matches the `visible_users` view in the database. I'm unsure why
`name` wasn't already included given that `username` is.
- Adds a new `initiator` field to `codersdk.AIBridgeInterception` which
contains `codersdk.MinimalUser` (ID, username, name, avatar URL)
- Removes `initiator_id` from `codersdk.AIBridgeInterception`
- Should be fine since we're still in early access
This change ensures task names are unique per user the same way we do
for workspaces. This ensures we don't create tasks that are impossible
to start due to another task being named the same creating a workspace
name conflict.

# Add API Key Scope Wildcards
This PR adds wildcard API key scopes (`resource:*`) for all RBAC resources to ensure every resource has a matching wildcard value. It also adds all individual `resource:action` scopes to the API documentation and TypeScript definitions.
The changes include:
- Adding a new database migration (000377) that adds wildcard API key scopes
- Updating the API documentation to include all available scopes
- Enhancing the scope generation scripts to include all resource wildcards
- Updating the TypeScript definitions to match the expanded scope list
These changes make creating API keys with comprehensive permissions for specific resource types easier.
# Add Composite API Key Scopes
This PR adds high-level composite API key scopes to simplify token creation with common permission sets:
- `coder:workspaces.create` - Create and update workspaces
- `coder:workspaces.operate` - Read and update workspaces
- `coder:workspaces.delete` - Read and delete workspaces
- `coder:workspaces.access` - Read, SSH, and connect to workspace applications
- `coder:templates.build` - Read templates and create/read files
- `coder:templates.author` - Full template management with insights
- `coder:apikeys.manage_self` - Manage your own API keys
These composite scopes are persisted in the database and expanded during authorization, providing a more intuitive way to grant permissions compared to the granular resource:action scopes.
# Canonicalize API Key Scopes
This PR introduces canonical API key scopes with a `coder:` namespace prefix to avoid collisions with low-level resource:action names. It:
1. Renames special API key scopes in the database:
- `all` → `coder:all`
- `application_connect` → `coder:application_connect`
2. Adds support for a new `scopes` field in the API key creation request, allowing multiple scopes to be specified while maintaining backward compatibility with the singular `scope` field.
3. Updates the API documentation to reflect these changes, including the new endpoint for listing public API key scopes.
4. Ensures backward compatibility by mapping between legacy and canonical scope names in relevant code paths.
Breaking API Change:
> The presence of the `ip` field on `codersdk.ConnectionLog` cannot be
guaranteed, and so the field has been made optional. It may be omitted
on API responses.
When running a scaletest, I noticed logs of the form:
```

error= 1 error occurred:
* pq: null value in column "ip" of relation "connection_logs" violates not-null constraint
```
to ensure logs are never omitted from the connection log due to a
missing IP again (i.e. I'm not sure if we can always rely on a valid,
parseable, IP from `(http.Request).RemoteAddr`), I've removed the `NOT
NULL` constraint on `ip` on `connection_logs`, and made `ip` on the API
response optional.
The specific cause for these null IPs was the
`/workspaceproxies/me/issue-signed-app-token [post]` endpoint
constructing it's own `http.Request` without a `RemoteAddr` set, and
then passing that to the token issuer.
To solve this, we'll have workspace proxies send the real IP of the
client when calling `/workspaceproxies/me/issue-signed-app-token [post]`
via the header `Coder-Workspace-Proxy-Real-IP`.
## Description
Adds support for sending an ad‑hoc custom notification to the
authenticated user via API and CLI. This is useful for surfacing the
result of scripts or long‑running tasks. Notifications are delivered
through the configured method and the dashboard Inbox, respecting
existing preferences and delivery settings.
## Changes
* New notification template: “Custom Notification” with a label for a
custom title and a custom message.
* New API endpoint: `POST /api/v2/notifications/custom` to send a custom
notification to the requesting user.
* New API endpoint: `GET /notifications/templates/custom` to get custom
notification template.
* New CLI subcommand: `coder notifications custom <title> <message>` to
send a custom notification to the requesting user.
* Documentation updates: Add a “Custom notifications” section under
Administration > Monitoring > Notifications, including instructions on
sending custom notifications and examples of when to use them.

This change adds a support-index for `GetAPIKeysLastUsedAfter`.

Change for tested time range: `170ms` -> `3.3ms`.

This change adds an index to optimize the
`GetProvisionerDaemonsWithStatusByOrganization` query.
Execution time dropped from `18s 838ms` to `107ms`.
see https://github.com/coder/internal/issues/959 but the tl; dr is:
- we call this DB query on an interval (every 15s) and it would be
called on each coderd replica as well
- the generated values update very infrequently (for our most used
internal template I saw the builds created/claimed update twice in a 1h
period)
- we have no index on the initiator ID, so this query has to scan the
entire workspace_builds table on every request
In reality this should likely just be a Prometheus metric, and
Prometheus can handle the counter reset behaviour at query time, but for
now this should at least cut the load of the query to 25% of it's
current impact.

- Removes GetManagedAgentCount query
- Adds new table `usage_events_daily` which stores aggregated usage

This pull request introduces support for external workspace management, allowing users to register and manage workspaces that are provisioned and managed outside of the Coder.
* Added has_external_agent field to workspace builds and template versions
Not used in coderd yet, see stack.
Adds two new packages:
- `coderd/usage`: provides an interface for the "Collector" as well as a stub implementation for AGPL
- `enterprise/coderd/usage`: provides an interface for the "Publisher" as well as a Tallyman implementation
Relates to https://github.com/coder/internal/issues/814
External auth refresh errors lose the original error thrown on the first
refresh. This PR saves that error to the database to be raised on
subsequent refresh attempts
Closes https://github.com/coder/internal/issues/780
## Summary of changes:
- added `user_secrets` table
- `user_secrets` table contains `env_name` and `file_path` fields which
are not used at the moment, but will be used in later PRs
- `user_secrets` table doesn't contain `value_key_id`, I will add it in
a separate migration in a dbcrypt PR
- on one hand I don't want to add fields which are not used (because
it's a risk smth may change in implementation later), on the other hand
I don't want to add too many migrations for user secrets table
- added unique sql indexes
- added sql queries for CRUD operations on user-secrets
- introduced new `ResourceUserSecret` resource
- basic unit-tests for CRUD ops and authorization behavior
- Role updates:
- owner:
- remove `ResourceUserSecret` from site-wide perms
- add `ResourceUserSecret` to user-wide perms
- orgAdmin
- remove `ResourceUserSecret` from org-wide perms; seems it's not
strictly required, because `ResourceUserSecret` is not tied to
organization in dbauthz wrappers?
- memberRole
- no need to change memberRole because it implicitly has access to
user-secrets thanks to the `allPermsExcept`
- is it enough changes to roles?
Main questions:
- [ ] We will have 2 migrations for user-secrets:
- initial migration (in current PR)
- adding `value_key_id` in dbcrypt PR
- is this approach reasonable?
- [ ] Are changes to roles's permissions are correct?
- [ ] Are changes in roles_test.go are correct?

Rather than having a per-app CORS behaviour setting and additionally a
template level setting for ports, this PR adds a single template level
CORS behaviour setting that is then used by all apps/ports for
workspaces created from that template.
The main changes are in `proxy.go` and `request.go` to:
a) get the CORS behaviour setting from the template
b) have `HandleSubdomain` bypass the CORS middleware handler if the
selected behaviour is `passthru`
c) in `proxyWorkspaceApp`, do not modify the response if the selected
behaviour is `passthru`
<!-- This is an auto-generated comment: release notes by coderabbit.ai

at the template level for all shared ports.
* Introduced a new "CORS Behavior" setting in the template creation and
settings forms.
* API endpoints and responses now include the optional `cors_behavior`
property for templates.
* Workspace apps and proxy now honor the specified CORS behavior,

## Description
This PR adds support for `description` and `icon` fields to
`template_version_presets`. These fields will allow displaying richer
information for presets in the UI, improving the user experience when
creating a workspace.
Both fields are optional, non-nullable, and default to empty strings.
## Changes
* Database migration with the addition of `description VARCHAR(128)` and
`icon VARCHAR(256)` columns to the `template_version_presets` table.
* Updated the `CreateWorkspacePageView` in the UI
Note: UI changes will be addressed in a separate PR
This PR introduces new build reason values to identify what type of
connection triggered a workspace build, helping to troubleshoot
workspace-related issues.
## Database Migration
Added migration 000349_extend_workspace_build_reason.up.sql that extends
the build_reason enum with new values:
```
dashboard, cli, ssh_connection, vscode_connection, jetbrains_connection
```
## Implementation
The build reason is specified through the API when creating new
workspace builds:
- Dashboard: Automatically sets reason to `dashboard` when users start
workspaces via the web interface
- CLI `start` command: Sets reason to `cli` when workspaces are started
via the command line
- CLI `ssh` command: Sets reason to ssh_connection when workspaces are
started due to SSH connections
- VS Code connections: Will be set to `vscode_connection` by the VS Code
extension through CLI hidden flag
(https://github.com/coder/vscode-coder/pull/550)
- JetBrains connections: Will be set to `jetbrains_connection` by the
Jetbrains Toolbox
(https://github.com/coder/coder-jetbrains-toolbox/pull/150) and
Jetbrains Gateway extension
(https://github.com/coder/jetbrains-coder/pull/561)

### Breaking Change (changelog note):
> User connections to workspaces, and the opening of workspace apps or ports will no longer create entries in the audit log. Those events will now be included in the 'Connection Log'.
Please see the 'Connection Log' page in the dashboard, and the Connection Log [documentation](https://coder.com/docs/admin/monitoring/connection-logs) for details. Those with permission to view the Audit Log will also be able to view the Connection Log. The new Connection Log has the same licensing restrictions as the Audit Log, and requires a Premium Coder deployment.
### Context
This is the first PR of a few for moving connection events out of the audit log, and into a new database table and web UI page called the 'Connection Log'.
This PR:
- Creates the new table
- Adds and tests queries for inserting and reading, including reading with an RBAC filter.
- Implements the corresponding RBAC changes, such that anyone who can view the audit log can read from the table
- Implements, under the enterprise package, a `ConnectionLogger` abstraction to replace the `Auditor` abstraction for these logs. (No-op'd in AGPL, like the `Auditor`)
- Routes SSH connection and Workspace App events into the new `ConnectionLogger`
- Updates all existing tests to check the values of the `ConnectionLogger` instead of the `Auditor`.
Future PRs:
- Add filtering to the query
- Add an enterprise endpoint to query the new table
- Write a query to delete old events from the audit log, call it from dbpurge.
- Implement a table in the Web UI for viewing connection logs.

# Remove unique constraint on OAuth2 provider app names
This PR removes the unique constraint on the `name` field in the `oauth2_provider_apps` table to comply with RFC 7591, which only requires unique client IDs, not unique client names.
Changes include:
- Removing the unique constraint from the database schema
- Adding migration files for both up and down migrations
- Removing the name uniqueness check in the in-memory database implementation
- Updating the unique constraint constants

# Implement OAuth2 Dynamic Client Registration (RFC 7591/7592)
This PR implements OAuth2 Dynamic Client Registration according to RFC 7591 and Client Configuration Management according to RFC 7592. These standards allow OAuth2 clients to register themselves programmatically with Coder as an authorization server.
Key changes include:
1. Added database schema extensions to support RFC 7591/7592 fields in the `oauth2_provider_apps` table
2. Implemented `/oauth2/register` endpoint for dynamic client registration (RFC 7591)
3. Added client configuration management endpoints (RFC 7592):
- GET/PUT/DELETE `/oauth2/clients/{client_id}`
- Registration access token validation middleware
4. Added comprehensive validation for OAuth2 client metadata:
- URI validation with support for custom schemes for native apps
- Grant type and response type validation
- Token endpoint authentication method validation
5. Enhanced developer documentation with:
- RFC compliance guidelines
- Testing best practices to avoid race conditions
- Systematic debugging approaches for OAuth2 implementations
The implementation follows security best practices from the RFCs, including proper token handling, secure defaults, and appropriate error responses. This enables third-party applications to integrate with Coder's OAuth2 provider capabilities programmatically.
This pull request implements RFC 8707, Resource Indicators for OAuth 2.0 (https://datatracker.ietf.org/doc/html/rfc8707), to enhance the security of our OAuth 2.0 provider.
This change enables proper audience validation and binds access tokens to their intended resource, which is crucial
for preventing token misuse in multi-tenant environments or deployments with multiple resource servers.
## Key Changes:
* Resource Parameter Support: Adds support for the resource parameter in both the authorization (`/oauth2/authorize`) and token (`/oauth2/token`) endpoints, allowing clients to specify the intended resource server.
* Audience Validation: Implements server-side validation to ensure that the resource parameter provided during the token exchange matches the one from the authorization request.
* API Middleware Enforcement: Introduces a new validation step in the API authentication middleware (`coderd/httpmw/apikey.go`) to verify that the audience of the access token matches the resource server being accessed.
* Database Schema Updates:
* Adds a `resource_uri` column to the `oauth2_provider_app_codes` table to store the resource requested during authorization.
* Adds an `audience` column to the `oauth2_provider_app_tokens` table to bind the issued token to a specific audience.
* Enhanced PKCE: Includes a minor enhancement to the PKCE implementation to protect against timing attacks.
* Comprehensive Testing: Adds extensive new tests to `coderd/oauth2_test.go` to cover various RFC 8707 scenarios, including valid flows, mismatched resources, and refresh token validation.
## How it Works:
1. An OAuth2 client specifies the target resource (e.g., https://coder.example.com) using the resource parameter in the authorization request.
2. The authorization server stores this resource URI with the authorization code.
3. During the token exchange, the server validates that the client provides the same resource parameter.
4. The server issues an access token with an audience claim set to the validated resource URI.
5. When the client uses the access token to call an API endpoint, the middleware verifies that the token's audience matches the URL of the Coder deployment, rejecting any tokens intended for a different resource.
This ensures that a token issued for one Coder deployment cannot be used to access another, significantly strengthening our authentication security.

This PR provides two commands:
* `coder prebuilds pause`
* `coder prebuilds resume`
These allow the suspension of all prebuilds activity, intended for use
if prebuilds are misbehaving.
## Summary
This PR implements critical MCP OAuth2 compliance features for Coder's authorization server, adding PKCE support, resource parameter handling, and OAuth2 server metadata discovery. This brings Coder's OAuth2 implementation significantly closer to production readiness for MCP (Model Context Protocol)
integrations.
## What's Added
### OAuth2 Authorization Server Metadata (RFC 8414)
- Add `/.well-known/oauth-authorization-server` endpoint for automatic client discovery
- Returns standardized metadata including supported grant types, response types, and PKCE methods
- Essential for MCP client compatibility and OAuth2 standards compliance
### PKCE Support (RFC 7636)
- Implement Proof Key for Code Exchange with S256 challenge method
- Add `code_challenge` and `code_challenge_method` parameters to authorization flow
- Add `code_verifier` validation in token exchange
- Provides enhanced security for public clients (mobile apps, CLIs)
### Resource Parameter Support (RFC 8707)
- Add `resource` parameter to authorization and token endpoints
- Store resource URI and bind tokens to specific audiences
- Critical for MCP's resource-bound token model
### Enhanced OAuth2 Error Handling
- Add OAuth2-compliant error responses with proper error codes
- Use standard error format: `{"error": "code", "error_description": "details"}`
- Improve error consistency across OAuth2 endpoints
### Authorization UI Improvements
- Fix authorization flow to use POST-based consent instead of GET redirects
- Remove dependency on referer headers for security decisions
- Improve CSRF protection with proper state parameter validation
## Why This Matters
**For MCP Integration:** MCP requires OAuth2 authorization servers to support PKCE, resource parameters, and metadata discovery. Without these features, MCP clients cannot securely authenticate with Coder.
**For Security:** PKCE prevents authorization code interception attacks, especially critical for public clients. Resource binding ensures tokens are only valid for intended services.
**For Standards Compliance:** These are widely adopted OAuth2 extensions that improve interoperability with modern OAuth2 clients.
## Database Changes
- **Migration 000343:** Adds `code_challenge`, `code_challenge_method`, `resource_uri` to `oauth2_provider_app_codes`
- **Migration 000343:** Adds `audience` field to `oauth2_provider_app_tokens` for resource binding
- **Audit Updates:** New OAuth2 fields properly tracked in audit system
- **Backward Compatibility:** All changes maintain compatibility with existing OAuth2 flows
## Test Coverage
- Comprehensive PKCE test suite in `coderd/identityprovider/pkce_test.go`
- OAuth2 metadata endpoint tests in `coderd/oauth2_metadata_test.go`
- Integration tests covering PKCE + resource parameter combinations
- Negative tests for invalid PKCE verifiers and malformed requests
## Testing Instructions
```bash
# Run the comprehensive OAuth2 test suite
./scripts/oauth2/test-mcp-oauth2.sh
Manual Testing with Interactive Server
# Start Coder in development mode
./scripts/develop.sh
# In another terminal, set up test app and run interactive flow
eval $(./scripts/oauth2/setup-test-app.sh)
./scripts/oauth2/test-manual-flow.sh
# Opens browser with OAuth2 flow, handles callback automatically
# Clean up when done
./scripts/oauth2/cleanup-test-app.sh
Individual Component Testing
# Test metadata endpoint
curl -s http://localhost:3000/.well-known/oauth-authorization-server | jq .
# Test PKCE generation
./scripts/oauth2/generate-pkce.sh
# Run specific test suites
go test -v ./coderd/identityprovider -run TestVerifyPKCE
go test -v ./coderd -run TestOAuth2AuthorizationServerMetadata
```
### Breaking Changes
None. All changes maintain backward compatibility with existing OAuth2 flows.

"Idle" is more accurate than "complete" since:
1. AgentAPI only knows if the screen is active; it has no way of knowing
if the task is complete.
2. The LLM might be done with its current prompt, but that does not mean
the task is complete either (it likely needs refinement).
The "complete" state will be reserved for future definition.
Additionally, in the case where the screen goes idle but the LLM never
reported a status update, we can get an idle icon without a message, and
it looks kinda janky in the UI so if there is no message I display the
state text.

Depends on https://github.com/coder/terraform-provider-coder/pull/408
This PR adds support for defining an **autoscaling block** for
prebuilds, allowing number of desired instances to scale dynamically
based on a schedule.
Example usage:
```
data "coder_workspace_preset" "us-nix" {
...
prebuilds = {
instances = 0 # default to 0 instances
scheduling = {
timezone = "UTC" # a single timezone is used for simplicity
# Scale to 3 instances during the work week
schedule {
cron = "* 8-18 * * 1-5" # from 8AM–6:59PM, Mon–Fri, UTC
instances = 3 # scale to 3 instances
}
# Scale to 1 instance on Saturdays for urgent support queries
schedule {
cron = "* 8-14 * * 6" # from 8AM–2:59PM, Sat, UTC
instances = 1 # scale to 1 instance
}
}
}
}
```
### Behavior
- Multiple `schedule` blocks per `prebuilds` block are supported.
- If the current time matches any defined autoscaling schedule, the
corresponding number of instances is used.
- If no schedule matches, the **default instance count**
(`prebuilds.instances`) is used as a fallback.
### Why
This feature allows prebuild instance capacity to adapt to predictable
usage patterns, such as:
- Scaling up during business hours or high-demand periods
- Reducing capacity during off-hours to save resources
### Cron specification
The cron specification is interpreted as a **continuous time range.**
For example, the expression:
```
* 9-18 * * 1-5
```
is intended to represent a continuous range from **09:00 to 18:59**,
Monday through Friday.
However, due to minor implementation imprecision, it is currently
interpreted as a range from **08:59:00 to 18:58:59**, Monday through
Friday.
This slight discrepancy arises because the evaluation is based on
whether a specific **point in time** falls within the range, using the
`github.com/coder/coder/v2/coderd/schedule/cron` library, which performs
per-minute matching rather than strict range evaluation.

Deletion of data is uncommon in our database, so the introduction of sub agents
and the deletion of them introduced issues with foreign key assumptions, as can
be seen in coder/internal#685. We could have only addressed the specific case by
allowing cascade deletion of stats as well as handling in the stats collector,
but it's unclear how many more such edge-cases we could run into.
In this change, we mark the rows as deleted via boolean instead, and filter them
out in all relevant queries.
Fixescoder/internal#685
The fields must be nullable because there’s a period of time between
inserting a row into the database and finishing the “plan” provisioner
job when the final value of the field is unknown.
Adds database migrations required for the Tasks feature.
There's a slight difference between the migrations in this PR and the
RFC: this PR adds `NOT NULL` constraints to the `has_ai_task` columns.
It was an oversight on my part when I wrote the RFC - I assumed the
`DEFAULT FALSE` value would make the columns implicitly NOT NULL, but
that's not the case with Postgres. We have no use for the NULL value.
The `DEFAULT FALSE` statement ensures that the migration will pass even
when there are existing rows in the template version and workspace
builds tables, so there's no danger in adding the `NOT NULL`
constraints.
