CONTEXT7_API_KEY |
Optional: Optional Context7 API key for higher rate limits and private repositories (can also be passed with --api-key, or as an Authorization: Bearer header on the hosted endpoint). |

What it does
Context7 is Upstash's MCP server for library documentation. Instead of relying on what a model learned in training, an assistant asks Context7 for the current docs and code examples of a library (for example Next.js, Supabase or MongoDB), optionally for a specific version, and gets them back as text to work from.
It has two tools: one resolves a library name into a Context7 library ID, the other fetches documentation for that ID matched to the user's question. You can name a library ID directly in a prompt (such as /supabase/supabase) to skip the lookup step. The documentation comes from Context7's own index, which is community-contributed; the README notes that its backend, parsing and crawling engines are private and not part of the repository.
You can connect to the hosted endpoint at https://mcp.context7.com/mcp over HTTP, or run the npm package @upstash/context7-mcp locally with npx (Node.js 20.18.1 or newer), which then calls the Context7 API. An API key from context7.com/dashboard is optional and gives higher rate limits and access to private repositories.

Tools 2
resolve-library-id- Resolves a general library name into a Context7-compatible library ID, ranked by relevance to the user's question.
query-docs- Retrieves documentation and code examples for a library using a Context7-compatible library ID (e.g. /vercel/next.js) and a question.
