Steven Masley d2f9ad783e feat(coderd/x/chatd): overlay user-set custom_headers at runtime
Threads the per-user custom_headers values stored on
mcp_server_user_header_values through the chatd MCP client so users
who provided a value for an admin-marked CustomHeadersUserKey see it
mixed into the outgoing request alongside the admin-static headers.

Changes:

- mcpclient.ConnectAll grows a fourth indexed input,
  []database.McpServerUserHeaderValue, which buildAuthHeaders
  consults inside the custom_headers branch to overlay per-user
  values on top of admin static headers, scoped to
  cfg.CustomHeadersUserKeys.
- chatd loads the user's stored header values via
  GetMCPServerUserHeaderValuesByUserID alongside the existing
  GetMCPServerUserTokensByUserID call and threads them into
  ConnectAll. A missing row is non-fatal: admin headers still
  ship, user-keyed headers are simply absent and a warning is
  logged.
- mcpclient.go inlines its own DefaultTransport clone for test
  isolation, replacing the standalone helper in mcphttpclient.go,
  which is removed.

Coder is a self-hosted platform for cloud development environments and AI coding agents. Workspaces are defined with Terraform, connected through a secure Wireguard® tunnel, and automatically shut down when not used. Coder Agents runs a native AI coding agent whose loop executes in the control plane on your infrastructure, with no API keys in workspaces.

  • Define cloud development environments in Terraform
    • EC2 VMs, Kubernetes Pods, Docker Containers, etc.
  • Automatically shutdown idle resources to save on costs
  • Onboard developers in seconds instead of days
  • Delegate coding work to AI agents on your infrastructure
    • Bring any model (Anthropic, OpenAI, Google, Bedrock, self-hosted)
    • No LLM credentials in workspaces, user identity on every action
    • Centralized model governance, cost tracking, and audit logging

Coder platform showing templates and a running workspace

Quickstart

The most convenient way to try Coder is to install it on your local machine and experiment with provisioning cloud development environments using Docker (works on Linux, macOS, and Windows).

# First, install Coder
curl -L https://coder.com/install.sh | sh

# Start the Coder server (caches data in ~/.cache/coder)
coder server

# Navigate to http://localhost:3000 to create your initial user,
# create a Docker template and provision a workspace

Install

The easiest way to install Coder is to use the install script for Linux and macOS. For Windows, use the latest ..._installer.exe file from GitHub Releases.

curl -L https://coder.com/install.sh | sh

You can run the install script with --dry-run to see the commands that will be used to install without executing them. Run the install script with --help for additional flags.

See install for additional methods.

Once installed, you can start a production deployment with a single command:

# Automatically sets up an external access URL on *.try.coder.app
coder server

# Requires a PostgreSQL instance (version 13 or higher) and external access URL
coder server --postgres-url <url> --access-url <url>

Use coder --help to get a list of flags and environment variables. See the install guides for a complete tutorial.
