Context7 MCP Relay

Context7 MCP Relay pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt as VSCode Language Model Tools, which means this extension works even if MCP was disabled in Github Copilot and VSCode

Usage

The Context7 MCP Relay is automatically registered when the extension activates. It provides the following capabilities:

Available Functions

1. context7_resolve-library-id - Resolves a package/product name to a Context7-compatible library ID
2. context7_get-library-docs - Fetches up-to-date documentation for a library

Features

This extension integrates with an MCP (Model Context Protocol) server to provide enhanced AI capabilities.

• Resolve library id: Resolves a package/product name to a Context7-compatible library ID and returns a list of matching libraries.

You MUST call this function before 'context7_get-library-docs' to obtain a valid Context7-compatible library ID UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query.

Selection Process:

1. Analyze the query to understand what library/package the user is looking for
2. Return the most relevant match based on:

• Name similarity to the query (exact matches prioritized)
• Description relevance to the query's intent
• Documentation coverage (prioritize libraries with higher Code Snippet counts)
• Trust score (consider libraries with scores of 7-10 more authoritative)

Response Format:

• Return the selected library ID in a clearly marked section
• Provide a brief explanation for why this library was chosen
• If multiple good matches exist, acknowledge this but proceed with the most relevant one
• If no good matches exist, clearly state this and suggest query refinements

For ambiguous queries, request clarification before proceeding with a best-guess match.

• Get library docs: Fetches up-to-date documentation for a library. You must call 'context7_resolve-library-id' first to obtain the exact Context7-compatible library ID required to use this tool, UNLESS the user explicitly provides a library ID in the format '/org/project' or '/org/project/version' in their query.
