Cursor config for Fetch MCP Server

npm install -g mcp-fetch-server

{
  "mcpServers": {
    "fetch-mcp-server": {
      "command": "npx",

      ]

Setup steps

1Open Cursor → Settings → MCP → Add new MCP server (or edit ~/.cursor/mcp.json directly).
2Paste the Fetch MCP Server config below into the "mcpServers" object.
3Fill in placeholder secrets, then save.
4Cursor reloads MCP servers automatically — check Settings → MCP for a green status dot.
5Ask Cursor to use one of Fetch MCP Server's tools to confirm it's connected.

Before you start

Node.js with npx (to run mcp-fetch-server), or global install via npm install -g mcp-fetch-server
Optional: yt-dlp installed for richer YouTube transcript extraction (falls back to direct page extraction)

Fetch MCP Server + Cursor FAQ

Where is the Cursor config file?

Cursor reads MCP servers from ~/.cursor/mcp.json. Paste the Fetch MCP Server config there under the "mcpServers" key and restart the client.

Is Fetch MCP Server safe to use with Cursor?

Includes SSRF protection that blocks private/localhost addresses and DNS rebinding, plus a response body size limit (MAX_RESPONSE_BYTES, default 10 MB) to prevent memory exhaustion.

How do I limit the size of fetched content?

Use the max_length parameter (default 5000 characters) and start_index (default 0) to paginate, or set the DEFAULT_LIMIT env var (set to 0 for no limit). MAX_RESPONSE_BYTES caps the raw response body size (default 10 MB).

Can I fetch through a proxy or with custom headers?

Yes. Every tool accepts an optional proxy URL (e.g. http://proxy:8080) and a headers object for custom request headers.

Does it protect against SSRF?

Yes. The server blocks requests to private/localhost addresses and guards against DNS rebinding, and limits response body size to prevent memory exhaustion.
