Context7
An MCP server that provides LLMs with up-to-date, version-specific documentation and code examples for programming libraries. Resolves library names to Context7 IDs, then retrieves current documentation and examples directly into the agent's context. Prevents hallucinated or outdated API references by pulling from live sources.
Best When
You are coding with an AI assistant and need accurate, current documentation for popular open source libraries rather than relying on the LLM's potentially outdated training data.
Avoid When
You primarily work with internal/private libraries, or you need guaranteed documentation accuracy. The community-contributed nature means coverage and quality vary by library.
Use Cases
- • Getting current API documentation while coding with an AI assistant
- • Preventing AI hallucination of deprecated or nonexistent API methods
- • Looking up version-specific library usage examples during development
- • Augmenting any MCP-compatible coding assistant with live documentation
Not For
- • Private or internal library documentation (community-contributed public docs only)
- • Non-programming documentation needs
- • Guaranteed-accurate documentation (community contributed, no accuracy guarantee)
