## MCP suite: real Datadog only

|

Every test under `tests/e2e/mcp/` must exercise the proxy against the real Datadog remote MCP server. Do not add a compose service, FastMCP fixture, mock upstream, or any other fake MCP host for this suite
|
||||
Every test under `tests/e2e/mcp/` must exercise the proxy against the real Datadog remote MCP server, except the two Linear OAuth tests `test_mcp_chat_completion_oauth_e2e.py` and `test_mcp_oauth_happy_path_e2e.py`. Do not add a compose service, FastMCP fixture, mock upstream, or any other fake MCP host for this suite
|
||||
|
||||
- Register via `register_datadog_mcp` in `tests/e2e/mcp/datadog_mcp.py` (or extend that helper if you need a different `toolsets=` / `allowed_tools` slice of the same Datadog endpoint). That posts `/v1/mcp/server` with `url=datadog_mcp_url(...)` and static headers `DD-API-KEY` / `DD-APPLICATION-KEY` from the process env
|
||||
- Auth is Datadog's documented CI/header path, not a browser OAuth authorize/token dance. Hard-fail when `DD_API_KEY` or `DD_APP_KEY` is missing (`assert_dd_mcp_creds`); never skip for a missing fake upstream
|
||||
- Prefer calling real Datadog tools that prove the product path (e.g. `search_datadog_logs` for list/call and permission denials). Seed a unique marker (`e2e-datadog-mcp-*`) in a chat completion when you need a log the tool can find; dual-read with `dd_logs` from conftest when delivery matters
|
||||
- Delete the MCP server (and any keys) through `resources.defer` the same way every other suite tears down
|
||||
- If a new MCP behavior cannot be covered with Datadog's tool surface, say so in the PR and get agreement before inventing another upstream; the default is always Datadog
|
||||
- The one standing exception is `test_mcp_chat_completion_oauth_e2e.py`. Datadog authenticates with the static `DD-API-KEY` / `DD-APPLICATION-KEY` headers and exposes no authorize/token dance at all, so it cannot exercise gateway-managed OAuth or per-user token seeding in any form. That test drives a real Linear MCP server instead; it is still a real remote upstream, so the no-mock, no-fixture rule above holds unchanged
|

- The two standing exceptions are `test_mcp_chat_completion_oauth_e2e.py` and `test_mcp_oauth_happy_path_e2e.py`. Datadog authenticates with the static `DD-API-KEY` / `DD-APPLICATION-KEY` headers and exposes no authorize/token dance at all, so these tests drive a real Linear MCP server instead; they are still real remote upstreams, so the no-mock, no-fixture rule above holds unchanged. The direct OAuth test also uses the existing live provider edge to inspect forwarded headers without replay, and owns a separate source-built gateway for cold restarts

## MCP OAuth happy path
|
||||
|
||||
`test_mcp_oauth_happy_path_e2e.py` runs one shared scenario with four variants:
|
||||
aggregate gateway SSO and explicitly configured per-server JWT, each directly
|
||||
against Linear and through the live provider edge. The edge forwards to real
|
||||
Linear without replay and compares the forwarded bearer to the encrypted
|
||||
canonical user/server credential. This observes the forwarding boundary, not
|
||||
Linear's internal logs. Direct variants independently exercise discovery
|
||||
|
||||
Use the existing database preparation, Prisma generation and Keycloak setup.
|
||||
Build and stage the dashboard from the tested checkout as in the UI runner.
|
||||
Provide `DATABASE_URL`, `LITELLM_MASTER_KEY`, `LITELLM_SALT_KEY`, `LITELLM_LICENSE`,
|
||||
and the `E2E_KEYCLOAK_*` settings. Capture a test-account Linear login using
|
||||
`mcp/linear_session_capture.py` and set `E2E_LINEAR_STORAGE_STATE` to that private
|
||||
file. The test workspace must contain a team. Do not publish browser state or
|
||||
raw test/proxy output
|
||||
|
||||
```bash
|
||||
E2E_MCP_OAUTH_LIVE=1 E2E_FIXTURE_MODE=live E2E_PROVIDER_CACHE=0 \
|
||||
uv run --no-sync pytest tests/e2e/mcp/test_mcp_oauth_happy_path_e2e.py \
|
||||
--rootdir=. --reruns 0
|
||||
```
|
||||
|
||||
The test starts and restarts its own source-built proxy on a free loopback port,
|
||||
retaining its database and SSO client but no Redis or process-local cache. It
|
||||
does not restart an existing proxy or clear shared databases. Gateway login,
|
||||
consent, immediate list/call and post-restart reconnect must all succeed. The
|
||||
aggregate client never injects a gateway header; the explicitly labeled JWT
|
||||
variant configures `x-litellm-api-key` for the first consent and reconnects with
|
||||
only its gateway JWT after restart
|
||||
|
||||
`.github/workflows/test-mcp-oauth-e2e.yml` automatically requests a run for
|
||||
same-repository pull requests changing MCP, gateway authentication/SSO, consent
|
||||
UI, dependencies or the relevant E2E harness/workflow paths. It retains manual
|
||||
`workflow_dispatch` for targeted verification. The four cases run in the
|
||||
protected `e2e-changed` environment after its normal deployment approval;
|
||||
reviewers should approve and inspect this separate OAuth check when it appears.
|
||||
Fork pull requests do not run this credentialed job; use a reviewed
|
||||
same-repository branch for their verification. The workflow's path-filtered
|
||||
check is not configured here as a globally required branch-protection check.
|
||||
Provision `E2E_LINEAR_STORAGE_STATE_B64` as a secret there and retain the existing E2E license/AWS role configuration. A missing or
|
||||
expired session fails the job; collection, deselection and skips are not passes.
|
||||
The generic changed-test job excludes this file because it requires an owned
|
||||
proxy and consent UI. No LLM call is needed
|
||||
|
||||
Coverage remains limited to authorization-code OAuth over HTTP. M2M, OBO,
|
||||
PKCE passthrough, static/BYOK, ID-JAG, forwarding, SigV4 and stdio are outside this
|
||||
scenario; consult the registry and LIT-3559 for their existing coverage and gaps.
|
||||
LIT-4506 owns broader isolation/failure regressions. LIT-7737 retains ownership
|
||||
of dependency/Python compatibility and its matrix; this test reuses its delivered
|
||||
environment and does not change dependency constraints or compatibility gates
