Context7, verificado

Claude Code

1. Run this in a terminal, in your project folder:

claude mcp add --transport http context7 https://mcp.context7.com/mcp

1. Start Claude Code and type /mcp. context7 should show as connected. To sign in for more access, pick it and choose Authenticate.

Add --scope user to make it available in every project, not just this one. Works without a key. An API key from Upstash raises the limits: send it as Authorization: Bearer <YOUR_API_KEY>.

Claude Desktop

1. Open Settings → Connectors and click Add custom connector.
2. Name it Context7 and paste this URL:

https://mcp.context7.com/mcp

1. Click Add, then Connect. Signing in to Upstash is optional.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

Añadir a claude.ai (se abre en una pestaña nueva)

1. Check that the URL reads https://mcp.context7.com/mcp and click Add.
2. Click Connect. Signing in to Upstash is optional.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under Organization settings → Connectors.

ChatGPT

1. On chatgpt.com, open Settings → Security and login and turn on Developer mode.
2. Go to chatgpt.com/plugins and click + to create an app for a remote MCP server.
3. Paste https://mcp.context7.com/mcp as the server URL and choose No authentication, or OAuth to sign in to Upstash for more access.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

Cursor

Añadir a Cursor (se abre en una pestaña nueva)

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

{
  "mcpServers": {
    "context7": {
      "url": "https://mcp.context7.com/mcp"
    }
  }
}

Works without a key. An API key from Upstash raises the limits: send it as Authorization: Bearer <YOUR_API_KEY>.

VS Code

Install in VS Code (se abre en una pestaña nueva)

Or from a terminal:

code --add-mcp '{"name":"context7","type":"http","url":"https://mcp.context7.com/mcp"}'

Or commit it to the repo in .vscode/mcp.json:

{
  "servers": {
    "context7": {
      "type": "http",
      "url": "https://mcp.context7.com/mcp"
    }
  }
}

Works without a key. An API key from Upstash raises the limits: send it as Authorization: Bearer <YOUR_API_KEY>.

Devin Desktop

1. Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):

{
  "mcpServers": {
    "context7": {
      "serverUrl": "https://mcp.context7.com/mcp"
    }
  }
}

1. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf. It reads serverUrl (or url) for remote servers. Works without a key. An API key from Upstash raises the limits: send it as Authorization: Bearer <YOUR_API_KEY>.

Codex

codex mcp add context7 --url https://mcp.context7.com/mcp

Or edit ~/.codex/config.toml directly:

[mcp_servers.context7]
url = "https://mcp.context7.com/mcp"

Works without a key. An API key from Upstash raises the limits: send it as Authorization: Bearer <YOUR_API_KEY>.

Gemini CLI

gemini mcp add --transport http context7 https://mcp.context7.com/mcp

Then, inside Gemini CLI, run /mcp auth context7 to sign in (optional).

This adds it to the current project. Add -s user to use it everywhere. Works without a key. An API key from Upstash raises the limits: send it as Authorization: Bearer <YOUR_API_KEY>.

Any client

Most clients accept this shape. Some name the URL field differently: serverUrl in Devin Desktop, httpUrl in Gemini CLI’s settings file.

{
  "mcpServers": {
    "context7": {
      "type": "http",
      "url": "https://mcp.context7.com/mcp"
    }
  }
}

Zed puts servers under context_servers in its settings. Cline needs "type": "streamableHttp", or it assumes SSE.

Client only starts local servers? Bridge it with npx -y mcp-remote https://mcp.context7.com/mcp.

Works without a key. An API key from Upstash raises the limits: send it as Authorization: Bearer <YOUR_API_KEY>.
