mcp-research（MCP 研究）

MCP Docs and Research (Context7, Exa, Jina)

Invocation Notice

• Inform the user when this skill is being invoked by name: mcp-research.

Overview

Use MCP-provided tools to retrieve current, verifiable information instead of relying on memory for fast-changing libraries, APIs, and ecosystem guidance.

When to Use

• Working with any external library or framework (for example, FastAPI, SQLAlchemy, pandas, boto3, or requests).
• Installing or upgrading dependencies and verifying current versions or migration guidance.
• Implementing features tied to third-party SDKs or APIs.
• Debugging behavior that may be version-specific.
• Looking up current best practices, changelogs, or breaking changes.

Tool Selection

1. Use mcp__context7__resolve-library-id and mcp__context7__query-docs for official library documentation and API usage.
2. Use mcp__exa__get_code_context_exa for code-centric examples across docs, GitHub, and Stack Overflow.
3. Use mcp__exa__web_search_exa for broader current web context (announcements, release notes, ecosystem updates).
4. Use mcp__jina__search_web to discover relevant pages, then mcp__jina__read_url for clean page extraction.
5. Use mcp__jina__search_arxiv and mcp__jina__extract_pdf only when the task needs paper-level or PDF-structured research.

Default Workflow

1. Classify the request: official API docs, implementation examples, or broad web research.
2. Start with the narrowest reliable source:

- Official docs first (Context7) for API correctness. - Add Exa/Jina only when you need cross-source confirmation or broader context.

1. For Context7 docs, always resolve the library id before querying docs unless the exact /org/project id is already provided.
2. Keep queries specific (library + feature + version/error) to reduce noisy results.
3. Synthesize findings and clearly separate sourced facts from inferences.

Quality Rules

• Prefer primary/official documentation for API signatures and behavior.
• For dependency/version decisions, verify with current documentation before recommending versions.
• Avoid unsupported claims; cite concrete tool findings.
• If sources conflict, report the conflict and recommend the safest path (pin version, test in isolation, or check release notes).
• If coverage is weak, state limits explicitly and proceed with best available evidence.
