Add a periodic purge job for `boundary_logs` rows past their retention
threshold, following the same pattern as the existing audit log and
connection log purge jobs in `dbpurge`.
Expose a `--boundary-log-retention` deployment flag (env
`CODER_BOUNDARY_LOG_RETENTION`, YAML `retention.boundary_logs`). Default
is `0` (keep indefinitely). When set to a positive duration, `purgeTick`
deletes rows where `captured_at` is older than the threshold in batches
of 10,000, matching other log purge operations. The `boundary_logs`
label is added to the `records_purged_total` Prometheus counter.
Also removes the random-UUID fallback for `OwnerID` in
`dbgen.BoundarySession`. The previous fallback generated a UUID that
could never satisfy the `boundary_sessions_owner_id_fkey` FK constraint,
masking test setup bugs. Callers must now provide a valid user ID or
accept NULL (the legitimate "user deleted" state).
Subdomain app routing derived the app identity from
httpapi.RequestHost, which returned the client-supplied
X-Forwarded-Host header verbatim. No middleware validated or stripped
that header, so a request from an untrusted peer could forge it. Since
the application_connect cookie is scoped to the wildcard apps domain,
JavaScript in a share=authenticated app could fetch() with a forged
X-Forwarded-Host pointing at a victim's owner-only app; coderd routed
and authorized the request as the victim and returned the private app
response same-origin to the attacker.
Replace RequestHost with httpmw.EffectiveHost, which honors
X-Forwarded-Host only when the original socket peer is a configured
trusted origin, otherwise falling back to the received Host header.
This ties host trust to the same RealIPConfig model already used for
X-Forwarded-For and -Proto. Wire it into HandleSubdomain for both
coderd and wsproxy, and log both the effective host and the raw
received_host.
Add coverage: EffectiveHost unit tests assert the trust decision uses
the socket peer rather than the spoofable forwarded client IP, and a
HandleSubdomain test confirms a forged X-Forwarded-Host from an
untrusted peer never reaches token resolution.

We cannot disable a feature which was previously enabled; this is a BC
break.
This is also using `AIGatewayRoutingEnabled` which will be removed in
the next release.
Problem: CODER_AI_GATEWAY_ENABLED defaulted to true, which both started
the in-memory gateway and enabled the licensed FeatureAIBridge. As a
result, deployments that never configured AI Gateway saw a spurious "AI
Governance add-on is required" warning whenever they had an older
(non-add-on) Premium license, since the feature was enabled-and-entitled
by default.
Fix: Decouple "external AI Gateway API enabled" from "in-memory daemon
running," so the external/licensed surface is off by default while Coder
Agents retain access by default.
- Adds server-side and client-side validation for
CODER_CONFIGSSH_HOSTNAME_SUFFIX and CODER_SSH_CONFIG_OPTIONS.
- **Server-side breaking change:** invalid values for either of these will cause `coderd` to exit with an error.
- Client-side: `coder config-ssh` will exit with an error if it detects invalid config.
- Adds tests for the above
Local smoke-testing: ran `develop.sh --env-file <path to an env file
containing badness>`. Validated that server startup failed as expected.

Replace the env-based `BuildProviders` with a DB-backed loader. The database is now the single source of truth for runtime provider configuration; env config arrives via `SeedAIProvidersFromEnv` (run at boot) and `BuildProviders` reads it back as `aibridge.Provider` instances. `cli/server.go` and `enterprise/cli/server.go` both call the same path, so aibridged and aibridgeproxyd see the same provider set.
Per-provider `DumpDir` is replaced by a top-level `CODER_AI_GATEWAY_DUMP_DIR` base; each provider's effective dump path is `<base>/<provider name>`.
`CODER_AI_GATEWAY_ENABLED` / `CODER_AIBRIDGE_ENABLED` is now being defaulted to `true` now that it will be used by Coder Agents.
If you previously had this value disabled explicitly, that value will persist.
Adds options matching new AI Gateway naming.
New options are added as alias for old options. Old options are still
working.
Old options have deprecated message.
No conflict detection was added.
Updated documentation so it mentions only new options. Added note about
old options still working.

## Description
Removes 429 (Too Many Requests) from the circuit breaker failure conditions. Rate limiting is now handled by automatic key failover instead of tripping the circuit breaker.
## Changes
`DefaultIsFailure` no longer treats 429 as a circuit breaker failure. The circuit breaker now only trips on server overload responses (503, 529).
Tests and integration tests updated to use 503 instead of 429 for tripping circuits. Description strings in deployment config updated to reflect the change.

## 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

## 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`

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/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.
