context7-docs

Fetch latest documentation and code snippets for any library/framework via Context7 MCP (Upstash).

Prerequisites

• mcporter installed (/opt/homebrew/bin/mcporter)
• Context7 server configured: mcporter config add context7 --transport http --url "https://mcp.context7.com/mcp"
• Verify: mcporter list context7 --schema

Tools Available

| Tool | Purpose | |------|---------| | resolve-library-id | Find Context7 library ID from a name | | query-docs | Fetch docs/snippets for a library ID |

Usage

Step 1: Resolve Library ID

mcporter call context7.resolve-library-id \
  query="How to set up authentication" \
  libraryName="next.js" \
  --output json

Returns matching libraries with:

• Library ID: /org/project format (e.g. /vercel/next.js)
• Code Snippets: count of available examples
• Source Reputation: High/Medium/Low
• Benchmark Score: quality indicator (max 100)
• Versions: available version-specific IDs

Step 2: Query Documentation

mcporter call context7.query-docs \
  libraryId="/vercel/next.js" \
  query="app router middleware setup" \
  --output json

Returns up-to-date documentation and code examples.

Rules

• Always resolve-library-id first, then query-docs (unless user provides /org/project format directly).
• Max 3 calls per tool per question.
• Pick library with highest Benchmark Score + Source Reputation for ambiguous matches.
• Version-specific queries: use /org/project/version format from resolve results.

Integration Pattern for Subagents

When a subagent needs latest docs for implementation:

1. mcporter call context7.resolve-library-id query="<task description>" libraryName="<lib>"
2. Pick best library ID from results
3. mcporter call context7.query-docs libraryId="<id>" query="<specific question>"
4. Use returned docs/snippets in implementation

Common Libraries

| Library | Likely ID | |---------|-----------| | Next.js | /vercel/next.js or /websites/nextjs | | React | /facebook/react | | Prisma | /prisma/prisma | | Tailwind | /tailwindlabs/tailwindcss | | Stripe | /stripe/stripe-node |

Always verify with resolve-library-id — IDs may change.
