## Summary
Adds `--ai-gateway-allow-byok` deployment option to control whether
users can use Bring Your Own Key (BYOK) mode with AI Gateway.
When disabled (`--ai-gateway-allow-byok=false`), BYOK requests are
rejected with a 403 and a message directing the admin to enable the
flag. Centralized key authentication works regardless of this setting.
Defaults to `true` (BYOK allowed).

## Description
Blocks `CONNECT` tunnels to private and reserved IP ranges in
aibridgeproxyd, preventing the proxy from being used to reach internal
networks.
The Coder access URL is always exempt (hostname+port match) so the proxy
can reach its own deployment. It is possible to exempt additional ranges
via `CODER_AIBRIDGE_PROXY_ALLOWED_PRIVATE_CIDRS`.
DNS rebinding is handled differently per path:
* Direct (no upstream proxy): validate the resolved IP right before the
TCP dial, no window between check and connect.
* Upstream proxy: Resolves and checks before forwarding to the upstream
dialer. A small rebinding window exists since the upstream proxy
re-resolves independently.
## Changes
* Add blocked IP denylist covering private, reserved, and
special-purpose ranges
* Add `AllowedPrivateCIDRs` option with CLI flag and env var
* Wire IP checks into `proxy.ConnectDial` for both upstream and direct
paths
* Add tests for blocked/allowed cases across direct dial, upstream
proxy, CIDR exemptions, and CoderAccessURL exemption
Notes: documentation will be handled in a follow-up PR.
Closes: https://github.com/coder/security/issues/124
_Disclaimer: implemented by a Coder Agent using Claude Opus 4.6._
Marks the injected MCP approach in AI Bridge as deprecated across the
codebase.
## Changes
- **`codersdk/deployment.go`**: Deprecated `ExternalAuthConfig.MCPURL`,
`.MCPToolAllowRegex`, `.MCPToolDenyRegex` fields; deprecated and hid the
`--aibridge-inject-coder-mcp-tools` server flag; deprecated
`AIBridgeConfig.InjectCoderMCPTools`.
- **`coderd/externalauth/externalauth.go`**: Deprecated `Config.MCPURL`,
`.MCPToolAllowRegex`, `.MCPToolDenyRegex`.
- **`enterprise/aibridgedserver/aibridgedserver.go`**: Added runtime
deprecation warning when `CODER_AIBRIDGE_INJECT_CODER_MCP_TOOLS` is
enabled; deprecated `getCoderMCPServerConfig`.
- **`enterprise/aibridged/mcp.go`**: Deprecated `MCPProxyBuilder`
interface and `MCPProxyFactory` struct.
- **`docs/ai-coder/ai-bridge/mcp.md`**: Added deprecation warning
banner.
## Description
Adds optional TLS support for the AI Bridge Proxy listener. When TLS cert and key files are provided, the proxy serves over HTTPS instead of plain HTTP.
## Changes
* New configuration options to enable TLS on the proxy listener
* Wraps the TCP listener in `tls.NewListener` when configured
* Tests for validation errors, invalid files, and full integration (tunneled + MITM) through a TLS listener
Note: Documentation for TLS listener setup and client configuration will be handled in a follow-up PR.

## Description
Renames internal fields, variables, and comments related to the proxy's certificate/key configuration to explicitly reference their MITM CA purpose.
The AI Bridge Proxy uses a CA certificate to sign dynamically generated leaf certificates during MITM interception of HTTPS traffic from AI clients. With the upcoming introduction of TLS listener certificates (for serving the proxy itself over HTTPS, implemented upstack https://github.com/coder/coder/pull/22411), the previous generic naming would become ambiguous. This refactor makes it clear which certificate is which.
No user-facing flags, environment variables, YAML keys, or JSON fields were changed, this is purely an internal rename to avoid confusion going forward.

## Description
Mark `--ssh-hostname-prefix` flag and `CODER_SSH_HOSTNAME_PREFIX` env
variable as deprecated, recommending users to use
`--workspace-hostname-suffix` / `CODER_WORKSPACE_HOSTNAME_SUFFIX`
instead for consistency with Coder Desktop.
The deprecated option is now hidden from help output and docs but
remains functional for backward compatibility. When used, it will show a
deprecation warning pointing to the recommended alternative.
## Changes
- Added `UseInstead` pointing to `workspace-hostname-suffix` option
(triggers deprecation warning)
- Set `Hidden: true` to hide from CLI help and documentation
- Updated description to mention deprecation
- Regenerated docs and help files via `make gen`
Closes#18156

This undeprecates the `allow-workspace-renames` flag. IIUC, the 'danger'
with using this flag is that the workspace name might have been used in
the definition of some other terraform resources within template code,
so a rename could cause problems such as with persistent disks.

## Summary
Add circuit breaker support for AI Bridge to protect against cascading
failures from upstream AI provider rate limits (HTTP 429, 503, and
Anthropic's 529 overloaded responses).
## Changes
- Add 5 new CLI options for circuit breaker configuration:
- `--aibridge-circuit-breaker-enabled` (default: false)
- `--aibridge-circuit-breaker-failure-threshold` (default: 5)
- `--aibridge-circuit-breaker-interval` (default: 10s)
- `--aibridge-circuit-breaker-timeout` (default: 30s)
- `--aibridge-circuit-breaker-max-requests` (default: 3)
- Update aibridge dependency to include circuit breaker support
- Add tests for pool creation with circuit breaker providers
## Notes
- Circuit breaker is **disabled by default** for backward compatibility
- When enabled, applies to both OpenAI and Anthropic providers
- Uses sony/gobreaker internally via the aibridge library
## Testing
```
make test RUN=TestPoolWithCircuitBreakerProviders
```
## Description
Adds upstream proxy support for AI Bridge Proxy passthrough requests.
This allows aiproxy to forward non-allowlisted requests through an
upstream proxy. Currently, the only supported configuration is when
aiproxy is the first proxy in the chain (client → aiproxy → upstream
proxy).
## Changes
* Add `--aibridge-proxy-upstream` option to configure an upstream
HTTP/HTTPS proxy URL for passthrough requests
* Add `--aibridge-proxy-upstream-ca` option to trust custom CA
certificates for HTTPS upstream proxies
* Passthrough requests (non-allowlisted domains) are forwarded through
the upstream proxy
* MITM'd requests (allowlisted domains) continue to go directly to
aibridge, not through the upstream proxy
* Add tests for upstream proxy configuration and request routing
Closes: https://github.com/coder/internal/issues/1204
Closes https://github.com/coder/coder/issues/21360
A few considerations/notes:
- I've kept the number of conns to 10 in all other places, except coderd
- which uses the config value
- I opted to also make idle conns configurable; the greater the delta
between max open and max idle, the more connection churn
- Postgres maintains a [_process_ per
connection](https://www.postgresql.org/docs/current/connect-estab.html),
contrary to what the comment said previously
- Operators should be able to tune this, since process churn can
negatively affect OS scheduling
- I've set the value to `"auto"` by default so it's not another knob one
_has to_ twiddle, and sets max idle = max conns / 3

Because this affects more than just the template insights
page (specifically it also affects the deployment stats endpoint which
is shown on bottom bar and Prometheus), the group is being renamed
generically to just "stats collection". In the future if we need to
affect the other stats we can put those options here.
Then, because this change only affects a portion of stats, specifically
usage stats like connection and application time, bytes sent, etc, add a
new sub-group called "usage stats".
Then finally add back the "enable" flag. This also gives us a place to
one day place an "anonymize" flag if we need to go that route.
## Description
Adds the core AI Bridge MITM proxy daemon. This proxy intercepts HTTPS traffic, decrypts it using a configured CA certificate, and forwards requests to AIBridge for processing.
## Changes
* Added `aibridgeproxyd` package with the core proxy server implementation
* Added configuration options: `CODER_AIBRIDGE_PROXY_ENABLED`, `CODER_AIBRIDGE_PROXY_LISTEN_ADDR`, `CODER_AIBRIDGE_PROXY_CERT_FILE`, `CODER_AIBRIDGE_PROXY_KEY_FILE`
* Added tests for server initialization and MITM functionality
Closes https://github.com/coder/internal/issues/1180
Closes#20399
To summarize the original commit messages:
- Do not log stats to the database.
- Return errors on the insight endpoints.
- Update the frontend to show those errors.
- Also fixes an issue with getting the user status count via codersdk,
since I added a test to ensure it was not disabled by this flag and it
was sending the wrong payload.
## Summary
This adds configurable overload protection to the AI Bridge daemon to
prevent the server from being overwhelmed during periods of high load.
Partially addresses coder/internal#1153 (rate limits and concurrency
control; circuit breakers are deferred to a follow-up).
## New Configuration Options
| Option | Environment Variable | Description | Default |
|--------|---------------------|-------------|---------|
| `--aibridge-max-concurrency` | `CODER_AIBRIDGE_MAX_CONCURRENCY` |
Maximum number of concurrent AI Bridge requests. Set to 0 to disable
(unlimited). | `0` |
| `--aibridge-rate-limit` | `CODER_AIBRIDGE_RATE_LIMIT` | Maximum number
of AI Bridge requests per second. Set to 0 to disable rate limiting. |
`0` |
## Behavior
When limits are exceeded:
- **Concurrency limit**: Returns HTTP `503 Service Unavailable` with
message "AI Bridge is currently at capacity. Please try again later."
- **Rate limit**: Returns HTTP `429 Too Many Requests` with
`Retry-After` header.
Both protections are optional and disabled by default (0 values).
## Implementation
The overload protection is implemented as reusable middleware in
`coderd/httpmw/ratelimit.go`:
1. **`RateLimitByAuthToken`**: Per-user rate limiting that uses
`APITokenFromRequest` to extract the authentication token, with fallback
to `X-Api-Key` header for AI provider compatibility (e.g., Anthropic).
Falls back to IP-based rate limiting if no token is present. Includes
`Retry-After` header for backpressure signaling.
2. **`ConcurrencyLimit`**: Uses an atomic counter to track in-flight
requests and reject when at capacity.
The middleware is applied in `enterprise/coderd/aibridge.go` via
`r.Group` in the following order:
1. Concurrency check (faster rejection for load shedding)
2. Rate limit check
**Note**: Rate limiting currently applies to all AI Bridge requests,
including pass-through requests. Ideally only actual interceptions
should count, but this would require changes in the aibridge library.
## Testing
Added comprehensive tests for:
- Rate limiting by auth token (Bearer token, X-Api-Key, no token
fallback to IP)
- Different tokens not rate limited against each other
- Disabled when limit is zero
- Retry-After header is set on 429 responses
- Concurrency limiting (allows within limit, rejects over limit,
disabled when zero)
Adds `--disable-workspace-sharing` option.
Workspace sharing is disabled by not including user and group ACLs in
the workspace RBAC object, which prevents ACL-based authz.
Closes https://github.com/coder/internal/issues/1072
The commit also adds saving of workspace user/group ACLs in the test DB
data generator.
Replace hardcoded 7-day retention for workspace agent logs with
configurable retention from deployment settings. Defaults to 7d to
preserve existing behavior.
Depends on #21038
Updates #20743
Add `RetentionConfig` with server flags for configuring data retention:
- `--audit-logs-retention`: retention for audit log entries
- `--connection-logs-retention`: retention for connection logs
- `--api-keys-retention`: retention for expired API keys (default 7d)
Updates #20743
> [!CAUTION]
> In whichever release this lands, we've removed the ability to provide
keys via a YAML file (specifically on `openai_key`, `anthropic_key`,
`bedrock_access_key` and finally `bedrock_access_key_secret`). This will
need to be described in the release notes as to not break peoples AI
Bridge integrations upgrading from older versions.
This pull-request ensures that we can see the overview of the settings
of the `AI Bridge` feature within the `/deployment/observability` route.
This set of options only render when the `aibridge` feature flag is
enabled.
### Preview
Currently, when AI Bridge is enabled AND the `oauth2` and
`mcp-server-http` experiments are enabled we inject Coder's MCP tools
into all intercepted AI Bridge requests.
This PR introduces a config to control this behaviour.
**NOTE:** this is a backwards-incompatible change; previously these
tools would be injected automatically, now this setting will need to be
explicitly enabled.

# Add separate token lifetime limits for administrators
This PR introduces a new configuration option `--max-admin-token-lifetime` that allows administrators to create API tokens with longer lifetimes than regular users. By default, administrators can create tokens with a lifetime of up to 7 days (168 hours), while the existing `--max-token-lifetime` setting continues to apply to regular users.
The implementation:
- Adds a new `MaximumAdminTokenDuration` field to the session configuration
- Modifies the token validation logic to check the user's role and apply the appropriate lifetime limit
- Updates the token configuration endpoint to return the correct maximum lifetime based on the user's role
- Adds tests to verify that administrators can create tokens with longer and shorter lifetimes
- Updates documentation and help text to reflect the new option
This change allows organizations to grant administrators extended token lifetimes while maintaining tighter security controls for regular users.
Fixes#17395
Adds deployment option `CODER_WORKSPACE_HOSTNAME_SUFFIX`. This will eventually replace `CODER_SSH_HOSTNAME_PREFIX`, but we will do this slowly and support both for `coder ssh` for some time.
Note that the name is changed to "workspace" hostname, since this suffix will also be used for Coder Connect on Coder Desktop, which is not limited to SSH.
Third and final PR to address
https://github.com/coder/coder/issues/16230.
This PR enables GitHub OAuth2 login by default on new deployments.
Combined with https://github.com/coder/coder/pull/16629, this will allow
the first admin user to sign up with GitHub rather than email and
password.
We take care not to enable the default on deployments that would upgrade
to a Coder version with this change.
To disable the default provider an admin can set the
`CODER_OAUTH2_GITHUB_DEFAULT_PROVIDER` env variable to false.
First PR in a series to address
https://github.com/coder/coder/issues/16230.
Introduces support for logging in via the [GitHub OAuth2 Device
Flow](https://docs.github.com/en/apps/oauth-apps/building-oauth-apps/authorizing-oauth-apps#device-flow).
It's previously been possible to configure external auth with the device
flow, but it's not been possible to use it for logging in. This PR
builds on the existing support we had to extend it to sign ins.
When a user clicks "sign in with GitHub" when device auth is configured,
they are redirected to the new `/login/device` page, which makes the
flow possible from the client's side. The recording below shows the full
flow.
https://github.com/user-attachments/assets/90c06f1f-e42f-43e9-a128-462270c80fdd
I've also manually tested that it works for converting from
password-based auth to oauth.
Device auth can be enabled by a deployment's admin by setting the
`CODER_OAUTH2_GITHUB_DEVICE_FLOW` env variable or a corresponding config
setting.
Allows adding custom static CSP directives to Coder. Niche use case but
makes this easier then creating a reverse proxy that has to replace the
header. We want to preserve our directives, so having an append option
is preferred to a "replace" option via a reverse proxy.
Closes https://github.com/coder/coder/issues/15118
Resolves https://github.com/coder/coder/issues/15513
Disables notifications when both `$CODER_NOTIFICATIONS_WEBHOOK_ENDPOINT` and `$CODER_EMAIL_SMARTHOST` are unset.
Breaking change: `$CODER_EMAIL_SMARTHOST` is no longer set by default as `localhost:587`, meaning any deployments that make use of this default value will need to add it back.
