context7-mcp

What problem does it solve?

This Skill prevents AI hallucinations and ensures accurate code generation by providing access to up-to-date, version-specific documentation for over 8,500 libraries. It's especially critical for rapidly evolving APIs like Effect-TS, where training data can quickly become outdated.

Core Features & Use Cases

• resolve-library-id: Finds Context7-compatible library IDs from package names, ensuring you target the correct documentation source.
• get-library-docs: Fetches documentation for a specific library and topic, with options for code examples (mode: "code") or conceptual information (mode: "info").
• Critical for Effect-TS: Emphasizes its importance for Effect-TS due to frequent API changes and outdated training data, ensuring developers always have current API knowledge.
• Use Case: A developer needs to use a new feature in Effect-TS but is unsure of the exact API. They can use resolve-library-id to get the Effect-TS ID, then get-library-docs with topic: "Layer" and mode: "code" to fetch current code examples and function signatures, ensuring correct implementation.

Quick Start

Use the 'get-library-docs' tool to fetch code examples for creating an 'Effect Layer' from the '/effect-ts/effect' library.
