Best for
  • Teams that need the knowledge behind agent answers to stay inspectable, versioned, and portable
  • Local-first workflows that avoid hosted indexes, cloud registries, or cloud refresh workers
  • Scenarios requiring visible source references and conservative link resolution that warns instead of guessing
  • Deployments that want deterministic lexical search without an embedding service or LLM key
  • Developers using fast-moving frameworks/libraries worried about the AI suggesting stale code
  • Scenarios wanting zero-config documentation lookup
Not for
  • Retrieval quality that depends on vector or semantic search
  • Heading-based splitting, or Obsidian semantics like Canvas, Bases, PDFs, images, audio, video, and Dataview fields
  • Importing GitHub repository URLs directly (there is no dedicated importer; use a local checkout or docs folder)
  • Workflows that need to write back to the knowledge source or need agent-callable write tools
  • Looking up internal/private codebase documentation (Context7 targets publicly published open-source libraries)
  • Cases needing very high coverage of obscure, niche libraries (coverage depends on what Context7's platform has indexed)
Required permissions
  • Read local bundle directories and source cache and refresh state under ~/.okfy
  • Make same-origin network fetches to registered documentation sites when refresh is enabled (respects robots.txt by default)
  • Be launched as a stdio subprocess by an MCP client; the tools themselves are read-only
  • Usable without an API key (subject to a free-tier rate limit); CONTEXT7_API_KEY is an optional credential for higher quota
  • Read-only documentation lookup — no code execution or local filesystem access involved
Risks and side effects
  • HTML cleanup quality varies by documentation site and can affect search results
  • Preflight rejects DNS-resolved private targets, but fetch-time DNS is not IP-pinned, leaving a theoretical DNS rebinding risk
  • The default stale-while-refresh mode can briefly serve non-latest docs; blocking or off modes change this
  • One page or file becomes one concept with no heading-based splitting, so granularity can be coarse
  • `--force` replaces a non-empty output bundle, and unsafe output directories are rejected unless an explicit dangerous override is given
  • The free tier has limited quota — high-frequency use may hit rate limits
  • Documentation content comes from Context7's platform index, so its accuracy and freshness depend on that platform's crawl cadence
