MCP Servers for Cursor

Cursor reads its servers from .cursor/mcp.json. Of the 31 603 we track, 10 545 answer right now without any credentials, 3 371 sign you in through the browser and 1 326 want an API key you paste into the config. The blocks below are ready to paste — each is built from the address we actually reached, in the format this client expects.

How to add a server to Cursor

per project by default, or globally from your home directory

Create the file

In the repository you are working in. The folder name starts with a dot, so it will be hidden in Finder.

mkdir -p .cursor && touch .cursor/mcp.json

Paste the server block

Every server card on this site carries a block already shaped for this file — with the address we actually reached during our last check.

Reload and check the agent picked it up

Tools appear inside the agent, not in the editor chrome. If the list is empty, the file is either invalid JSON or in the wrong folder.

What it looks like

Things that trip people up with Cursor

Written from how Cursor reads its config, not from its release notes.

Project config or global?

A file in the repository applies only there; the same file in your home directory applies everywhere. The per-project variant is the safer default: a server with database credentials has no business being loaded in an unrelated repository.

How many servers is too many?

Every connected server adds its tools to what the model sees, and the median server exposes ten of them. Three or four servers is already a long list to choose from — connect what a project needs, not everything you own.

JSON, and JSON only

No trailing commas, no comments. A config copied from a Codex example will not work here at all: that one is TOML.

Nothing appears after editing the file

Three usual causes, in order of likelihood: the file is not valid JSON, it sits in the wrong folder, or the editor has not re-read it. Only after those is it worth suspecting the server — though 2 245 of them really do answer nothing.

Should the config be committed to the repository?

The file describes which servers a project needs, which is useful to share. Credentials in it are not — a token committed once is a token published. Keep secrets in the environment and the config in the repository.

Does a server work here if it works in Claude Desktop?

Almost always: the JSON shape is the same and the servers are identical. What differs is where the file lives and whether it applies to one project or to everything.

What does a server with no tools mean?

Either it is behind authorisation and refuses to describe itself to an anonymous client, or it is not answering at all. We show which of the two on every server page — the first case is working software, the second is not.

Same servers, other clients

the servers are the same — the config format is not

Windsurf

Editor with the agent built in. Takes stdio, streamable HTTP and SSE, and can carry an OAuth login for each of the three.

~/.codeium/windsurf/mcp_config.json

Cline

Autonomous agent living inside VS Code. Handles local processes and remote endpoints over streamable HTTP or SSE, but authorisation is on you — through headers or environment variables.

~/.cline/mcp.json

Gemini CLI

Google's command-line agent. Takes all three transports and carries a full OAuth flow for remote servers, including service-account impersonation.

~/.gemini/settings.json

JetBrains AI Assistant

Built into the JetBrains IDEs. Configured through the settings dialog rather than a file, and it can import a config you already wrote for another client.

Settings | Tools | AI Assistant | Model Context Protocol

OpenCode

Open-source terminal agent. Local and remote servers sit in the same mcp object, told apart by a type field, and tokens are kept outside the config.

opencode.json in the project, or ~/.config/opencode/opencode.json

Claude Code

Adds servers by command, so nothing to edit by hand. Handles both local processes and remote endpoints, including OAuth logins.

run in your terminal

VS Code

Works through GitHub Copilot's agent mode. Like Cursor, the config is per workspace rather than global.

.vscode/mcp.json

Codex

The only client here that uses TOML rather than JSON, so a config copied from elsewhere will not work as is.

~/.codex/config.toml

Claude Desktop

One global config for everything, so a server added here is available in every conversation.
