Client configuration

Cursor (.cursor/mcp.json)

{ "mcpServers": { "context7": { "command": "npx", "args": [ "-y", "@upstash/context7-mcp@4.0.5" ], "env": { "CONTEXT7_API_KEY": "your-context7-api-key-here" } } } }

VS Code (.vscode/mcp.json)

{ "servers": { "context7": { "command": "npx", "args": [ "-y", "@upstash/context7-mcp@4.0.5" ], "env": { "CONTEXT7_API_KEY": "your-context7-api-key-here" }, "type": "stdio" } } }

Replace the placeholders before connecting. Authorize in your client when prompted.

The Cursor JSON also works in Claude Desktop's local MCP configuration. Install the required runtime and local software first.
