## Context7 (no auth)
## Copilot hosted review

Check the current [GitHub MCP configuration documentation](https://docs.github.com/en/copilot/how-tos/copilot-on-github/customize-copilot/configure-mcp-servers)
before configuring a repository. These hosted constraints do not describe every
interactive MCP client:

| Capability | Hosted requirement |
| --------------------- | -------------------------------------------------------------------------------------------------------- |
| Configuration | Repository Settings > Copilot > MCP servers, shared with cloud agent |
| Defaults | GitHub and Playwright servers are enabled by default; verify the repository's actual state |
| Protocol | Tools only; resources and prompts are unsupported |
| Remote authentication | Remote OAuth servers are unsupported |
| Review tools | `tools/list` must return `annotations.readOnlyHint: true`; missing or false annotations exclude the tool |
| Credentials | Reference Agents secrets or variables prefixed `COPILOT_MCP_`; never commit values |

Use explicit read-tool allowlists and credentials restricted to the required
read access. An annotation is not an access-control boundary. Configured tools
can run without per-call approval; inspect the shared cloud-agent exposure too.
Configuration and credential changes require separate maintainer authorization.
A committed configuration draft does not prove that hosted settings are active.

Select the smallest useful profile from the repository's actual components:

- **`github`:** baseline for linked issue acceptance criteria, relevant PRs and
CI evidence. Read canonical organization policy and wiki contracts through
existing accessible sources. Do not broaden repository access implicitly.
- **`github-docs`:** the `github` baseline plus documentation lookup for
framework, API, or platform changes that need it, such as wiki Docusaurus or
Cloudflare changes.
Prefer official version-matched documentation; Context7 or Cloudflare's
documentation server is optional. Check actual tools and annotations before
selecting either. Operational Cloudflare access is outside this profile.
- **Linear:** optional addition only when a linked requirement is unavailable
in GitHub. Evaluate a restricted read-only API-key configuration if supported
by the current server; interactive OAuth availability does not prove hosted
compatibility. Do not mirror all tracker context into every review.

Playwright is relevant to browser behavior and previews only when suitable
tools are available to that review. Neither browser checks nor a third-party
documentation service is required for repositories that do not need them.
See [the health evidence procedure](../../runbooks/org-review.md#mcp-review-context)
for configuration, discovery, and invocation verification.

## Retrieve relevant context

When MCP tools are available and useful, read linked issue acceptance criteria,
canonical policies, and relevant CI evidence within the repository's approved
access scope. Look up version-matched official documentation when a changed
component needs it. Consult
[integration guidance](https://github.com/z-shell/.github/blob/main/.github/instructions/mcp-plugins.instructions.md#copilot-hosted-review)
for hosted compatibility and optional profiles. Use existing repository sources
or official documentation when an integration is unavailable. Do not require a
service merely because it is configured, or send private context to a new
service without authorization. Cite retrieved sources and report context gaps;
distinguish observed tool calls from configuration or discovery evidence.

Policy and deterministic health tooling own this gate even when optional
skills are not selected by the runtime.

### MCP review context

During health evaluation, record whether the repository selects the `github`
baseline, `github-docs`, or no MCP profile, and why that choice fits its actual
components. Optional services are not a health prerequisite. Follow
[integration guidance](../.github/instructions/mcp-plugins.instructions.md#copilot-hosted-review)
for hosted compatibility and tool selection. Keep these evidence dimensions
separate:

- **Configured:** identify the assessed repository revision, profile, runtime,
observation time, and source of the active hosted setting evidence. Record
server identities, selected tools, authentication mode and access boundaries
without credential values. A local declaration or a documented default alone
leaves actual hosted configuration unverified.
- **Discovered:** cite startup or `tools/list` evidence for that configuration,
including the tools' read-only annotations. A configured server may fail to
start, authenticate, or expose tools eligible for review.
- **Invoked:** cite an authorized review session or comment attribution showing
the server and tool used, reviewed head revision, and observed time. A passing
review or successful startup alone does not establish invocation or relevance.

Bind observations to the exact configuration revision or a digest of its
sanitized snapshot, plus the reviewed commit where applicable. Refresh evidence
after configuration, server version, access, or relevant repository changes;
an earlier successful call cannot verify the changed setup. Record unavailable
settings, logs, annotations, or calls as unverified, and preserve conflicting
evidence rather than inferring a pass from a local file.

Report this separately from skill readiness. Absence of optional MCP services
does not fail repository health. A selected profile whose required context is
unavailable has an explicit context gap, not a verified tailored review.
Keep administrative settings and private session evidence in the private
handoff; publish only authorized, public-safe conclusions.

Pilot the GitHub profile in the canonical owner and a standard plugin, then
documentation lookup in the wiki. Verify useful context retrieval on a
representative authorized review before wider configuration. A health
evaluation does not authorize settings changes, credentials, server installs,
or new hosted reviews.
