Searching MCP PRs, issues, and discussions

Where to search

• MCP Docs Server (mcp-docs MCP server → SearchModelContextProtocol tool): Authoritative for current spec content. Prefer this first for specification details, API references, and protocol concepts.
• Spec PRs & Issues: gh search prs / gh search issues in modelcontextprotocol/modelcontextprotocol (searches open and closed by default)
• Spec Discussions: https://github.com/modelcontextprotocol/modelcontextprotocol/discussions (requires GraphQL — see below)
• Org Discussions: https://github.com/orgs/modelcontextprotocol/discussions (requires GraphQL — see below)

For historical decisions, prioritize merged PRs and closed issues over open items.

Searching discussions

There is no gh search discussions command. Use the GraphQL API:

# Spec-repo discussions
gh api graphql -f query="query { search(query: \"repo:modelcontextprotocol/modelcontextprotocol <topic>\", type: DISCUSSION, first: 20) { nodes { ... on Discussion { title url body author { login } authorAssociation category { name } answer { author { login } authorAssociation body } } } } }"

# Org-wide discussions
gh api graphql -f query="query { search(query: \"org:modelcontextprotocol <topic>\", type: DISCUSSION, first: 20) { nodes { ... on Discussion { title url body author { login } authorAssociation category { name } answer { author { login } authorAssociation body } } } } }"

Search term variants

GitHub search does not split camelCase tokens. ToolAnnotations and Tool Annotations return almost entirely different results — search both.

• camelCase (ToolAnnotations, inputSchema): matches identifiers in code and schema
• Space-separated (Tool Annotations, input schema): matches natural-language discussion text

Skip kebab-case variants (tool-annotations) — GitHub tokenizes on hyphens, so they behave like the space-separated form but tend to return noisier results.

Deep diving into a PR

When to deep dive: a search result PR looks highly relevant to the topic, and you need to understand why a change was made, not just what changed

During a deep dive, look through:

• general conversation on the PR not tied to specific lines of code (repos/modelcontextprotocol/modelcontextprotocol/issues/{pr_number}/comments)
• comments left on specific lines of code during review (repos/modelcontextprotocol/modelcontextprotocol/pulls/{pr_number}/comments)
• top-level review bodies submitted with an approve/request-changes/comment verdict (repos/modelcontextprotocol/modelcontextprotocol/pulls/{pr_number}/reviews)

Each comment returned by these endpoints includes an author_association field — use it to identify maintainers (see Notable maintainer quotes).

Output format

PRs

- [#123](url) - PR Title (**Merged/Closed/Open** <date>)
  Brief summary of PR

Issues

- [#456](url) - Issue Title (**Open/Closed** <date>)
  Brief summary of issue

Discussions

- [#789](url) - Discussion Title (<date>)
  Brief summary of discussion content

Notable maintainer quotes

Identifying maintainers: The GitHub API includes an author_association field (REST) or authorAssociation (GraphQL) on every comment. Treat users with association MEMBER or OWNER as maintainers.

When maintainers make comments that reveal design intent, set direction, or explain rationale, quote them directly with attribution and a footnote:

"These would require a SEP. I think the general question here is about the taxonomy of hints." [^1] — @dsp-ant

Look for quotes that:

• Explain why a decision was made
• Set direction for future work
• Reject or redirect an approach
• Clarify the intended semantics of a feature

Key insights

Summarize the most important findings and any decisions or consensus reached.

Footnotes

Collect all sources as footnotes at the end. Every quote and claim presented in the output should have a corresponding footnote. For example:

[^1]: [#616 inline review comment by @dsp-ant](https://github.com/modelcontextprotocol/modelcontextprotocol/pull/616#discussion_r...)

[^2]: [#185 ToolAnnotations](https://github.com/modelcontextprotocol/modelcontextprotocol/pull/185)

[^3]: [Spec: Tool Annotations (2025-11-25)](https://modelcontextprotocol.io/specification/2025-11-25/server/tools)

General strategy

1. Generate search terms and variants (camelCase, space-separated, etc.)
2. Use SearchModelContextProtocol tool (if available) to search for current specification details and concepts
3. Expand search terms and variants based on new information
4. Search GitHub locations (use gh CLI tool if available)
5. Aggregate search results
6. Display output with summarized results, key insights, and direct attributions
