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
- Use
mcp__context7__resolve-library-idandmcp__context7__query-docsfor official library documentation and API usage. - Use
mcp__exa__get_code_context_exafor code-centric examples across docs, GitHub, and Stack Overflow. - Use
mcp__exa__web_search_exafor broader current web context (announcements, release notes, ecosystem updates). - Use
mcp__jina__search_webto discover relevant pages, thenmcp__jina__read_urlfor clean page extraction. - Use
mcp__jina__search_arxivandmcp__jina__extract_pdfonly when the task needs paper-level or PDF-structured research.
Default Workflow
- Classify the request: official API docs, implementation examples, or broad web research.
- 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.
- For Context7 docs, always resolve the library id before querying docs unless the exact
/org/projectid is already provided. - Keep queries specific (library + feature + version/error) to reduce noisy results.
- 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.
