_Disclosure: investigated and drafted with Claude Opus 5. I reviewed the
change and ran the tests locally._
Streaming Responses interceptions recorded no token usage when the
bridge was built with a nil `mcp.ServerProxier`, because
`recordTokenUsage` was called from inside the `i.mcpProxy != nil` branch
in `aibridge/intercept/responses/streaming.go`. Requests completed
normally and returned `200`, so traffic was served but metered as zero,
with no error surfaced. Upstream reports usage on the
`response.completed` event independently of tool injection, so the
proxier is not a valid precondition for recording it.
That state is reachable in production:
`coderd/aibridged/pool.go:255-265` treats proxier construction failure
as non-fatal ("MCP server injection can gracefully degrade") and caches
the resulting bridge via `SetWithTTL`, so one transient config-retrieval
error suppressed usage recording for every streaming Responses request
served by that bridge until its TTL expired.
This records usage for every completed response, guarded only on
`completedResponse`, matching `responses/blocking.go` and both
`chatcompletions` implementations. Per-iteration semantics are preserved
for the inner agentic loop.
The integration harness substituted a non-nil noop manager whenever no
proxier was supplied (`setupbridge.go:153-155`), so the nil path was
never exercised. `withoutMCP()` covers it.
Verification, with the fix reverted:
```
--- FAIL: TestResponsesStreamingRecordsTokenUsageWithoutMCP/without_mcp_proxy
Error: "[]" should have 1 item(s), but has 0
--- PASS: TestResponsesStreamingRecordsTokenUsageWithoutMCP/with_noop_mcp_proxy
```
and with it applied:
```
--- PASS: TestResponsesStreamingRecordsTokenUsageWithoutMCP/without_mcp_proxy
--- PASS: TestResponsesStreamingRecordsTokenUsageWithoutMCP/with_noop_mcp_proxy
--- PASS: TestResponsesStreamingRecordsTokenUsagePerAgenticIteration
```
The per-iteration case asserts exactly two records for the injected-tool
fixture, so decoupling the call from the proxier does not double-count
when the agentic loop iterates. `go test -race ./aibridge/...` passes
across all 15 packages.
Fixes #27885
One caveat on verification: I was unable to run `make gen` / `make
pre-commit` locally, as I do not have the full mise toolchain installed.
The change touches no codegen inputs (no SQL, protos, mocks, or
TypeScript), so I do not expect generated-file drift, but flagging it
rather than leaving it implied.
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
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.
