Install the Context7 MCP Server
Pick your client. Remote first: nothing to install, and you sign in with OAuth where the client supports it. Config shapes checked against each client's docs on 2026-10-25.
The URL also takes Authorization as a header (see its docs), for clients without OAuth sign-in.
Run in a terminal, then /mcp inside Claude Code to sign in. Add --scope project to share it via .mcp.json. docs
claude mcp add --transport http context7 https://mcp.context7.com/mcp
Customize > Connectors > Add > Add custom connector, paste this URL and sign in. It syncs to Claude Desktop and mobile. docs
https://mcp.context7.com/mcp
The free plan allows one custom connector. On Team and Enterprise an owner adds it under Organization settings > Connectors.

Security notes
- The remote server runs at mcp.context7.com, hosted by Upstash. You sign in with OAuth in clients that support it, or with Authorization header where OAuth isn't available, and it acts with your account's permissions.
- The local server runs with your user's permissions (npx downloads it from npm on first run).
