Context7 MCP - Up-to-date Code Docs For Any Prompt

❌ Without Context7

LLMs rely on outdated or generic information about the libraries you use. You get:

• ❌ Code examples are outdated and based on year-old training data
• ❌ Hallucinated APIs don't even exist
• ❌ Generic answers for old package versions

✅ With Context7

Context7 MCP pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt.

Add use context7 to your prompt in Cursor:

Create a basic Next.js project with app router. use context7

Create a script to delete the rows where the city is "" given PostgreSQL credentials. use context7

Context7 fetches up-to-date code examples and documentation right into your LLM's context.

• 1️⃣ Write your prompt naturally
• 2️⃣ Tell the LLM to use context7
• 3️⃣ Get working code answers

No tab-switching, no hallucinated APIs that don't exist, no outdated code generations.

🛠️ Installation

Requirements

• Node.js >= v18.0.0
• Cursor, Windsurf, Claude Desktop or another MCP Client

To install Context7 MCP Server for any client automatically via Smithery:

npx -y @smithery/cli@latest install @upstash/context7-mcp --client <CLIENT_NAME> --key <YOUR_SMITHERY_KEY>

You can find your Smithery key in the Smithery.ai webpage.

Go to: Settings -> Cursor Settings -> MCP -> Add new global MCP server

Pasting the following configuration into your Cursor ~/.cursor/mcp.json file is the recommended approach. You may also install in a specific project by creating .cursor/mcp.json in your project folder. See Cursor MCP docs for more info.

Since Cursor 1.0, you can click the install button below for instant one-click installation.

    }
  }
}

You can configure Context7 MCP in Visual Studio 2022 by following the Visual Studio MCP Servers documentation.

Add this to your Visual Studio MCP config file (see the Visual Studio docs for details):

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

Or, for a local server:

{
  "mcp": {
    "servers": {
      "context7": {
        "type": "stdio",
        "command": "npx",
        "args": ["-y", "@upstash/context7-mcp"]
      }
    }
  }
}

For more information and troubleshooting, refer to the Visual Studio MCP Servers documentation.

It can be installed via Zed Extensions or you can add this to your Zed settings.json. See Zed Context Server docs for more info.

{
  "context_servers": {
    "Context7": {
      "command": {
        "path": "npx",
        "args": ["-y", "@upstash/context7-mcp"]
      },
      "settings": {}
    }
  }
}

See Gemini CLI Configuration for details.

1. Open the Gemini CLI settings file. The location is ~/.gemini/settings.json (where ~ is your home directory).
2. Add the following to the mcpServers object in your settings.json file:

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@upstash/context7-mcp"]
    }
  }
}

If the mcpServers object does not exist, create it.

Run this command. See Claude Code MCP docs for more info.

Claude Code Remote Server Connection

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

Or using SSE transport:

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

Claude Code Local Server Connection

claude mcp add context7 -- npx -y @upstash/context7-mcp

Add this to your Claude Desktop claude_desktop_config.json file. See Claude Desktop MCP docs for more info.

{
  "mcpServers": {
    "Context7": {
      "command": "npx",
      "args": ["-y", "@upstash/context7-mcp"]
    }
  }
}

You can easily install Context7 through the Cline MCP Server Marketplace by following these instructions:

1. Open Cline.
2. Click the hamburger menu icon (☰) to enter the MCP Servers section.
3. Use the search bar within the Marketplace tab to find Context7.
4. Click the Install button.

Open the "Settings" page of the app, navigate to "Plugins," and enter the following JSON:

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@upstash/context7-mcp"]
    }
  }
}

Once saved, enter in the chat get-library-docs followed by your Context7 documentation ID (e.g., get-library-docs /nuxt/ui). More information is available on BoltAI's Documentation site. For BoltAI on iOS, see this guide.

If you prefer to run the MCP server in a Docker container:

1. Build the Docker Image:

   First, create a Dockerfile in the project root (or anywhere you prefer):

   FROM node:18-alpine
   
   WORKDIR /app
   
   # Install the latest version globally
   RUN npm install -g @upstash/context7-mcp
   
   # Expose default port if needed (optional, depends on MCP client interaction)
   # EXPOSE 3000
   
   # Default command to run the server
   CMD ["context7-mcp"]
   

   Then, build the image using a tag (e.g., context7-mcp). Make sure Docker Desktop (or the Docker daemon) is running. Run the following command in the same directory where you saved the Dockerfile:

   docker build -t context7-mcp .
   

2. Configure Your MCP Client:

   Update your MCP client's configuration to use the Docker command.

   Example for a cline_mcp_settings.json:

   {
     "mcpServers": {
       "Сontext7": {
         "autoApprove": [],
         "disabled": false,
         "timeout": 60,
         "command": "docker",
         "args": ["run", "-i", "--rm", "context7-mcp"],
         "transportType": "stdio"
       }
     }
   }
   

   Note: This is an example configuration. Please refer to the specific examples for your MCP client (like Cursor, VS Code, etc.) earlier in this README to adapt the structure (e.g., mcpServers vs servers). Also, ensure the image name in args matches the tag used during the docker build command.

The configuration on Windows is slightly different compared to Linux or macOS (Cline is used in the example). The same principle applies to other editors; refer to the configuration of command and args.

{
  "mcpServers": {
    "github.com/upstash/context7-mcp": {
      "command": "cmd",
      "args": ["/c", "npx", "-y", "@upstash/context7-mcp@latest"],
      "disabled": false,
      "autoApprove": []
    }
  }
}

🔨 Available Tools

Context7 MCP provides the following tools that LLMs can use:

• resolve-library-id: Resolves a general library name into a Context7-compatible library ID.

  • libraryName (required): The name of the library to search for

• get-library-docs: Fetches documentation for a library using a Context7-compatible library ID.

  • context7CompatibleLibraryID (required): Exact Context7-compatible library ID (e.g., /mongodb/docs, /vercel/next.js)
  • topic (optional): Focus the docs on a specific topic (e.g., "routing", "hooks")
  • tokens (optional, default 10000): Max number of tokens to return. Values less than the default value of 10000 are automatically increased to 10000.

💻 Development

Clone the project and install dependencies:

bun i

Build:

bun run build

Run the server:

bun run dist/index.js

CLI Arguments

context7-mcp accepts the following CLI flags:

• --transport <stdio|http|sse> – Transport to use (stdio by default).
• --port <number> – Port to listen on when using http or sse transport (default 3000).

Example with http transport and port 8080:

bun run dist/index.js --transport http --port 8080

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["tsx", "/path/to/folder/context7-mcp/src/index.ts"]
    }
  }
}

npx -y @modelcontextprotocol/inspector npx @upstash/context7-mcp

🚨 Troubleshooting

If you encounter ERR_MODULE_NOT_FOUND, try using bunx instead of npx:

{
  "mcpServers": {
    "context7": {
      "command": "bunx",
      "args": ["-y", "@upstash/context7-mcp"]
    }
  }
}

This often resolves module resolution issues in environments where npx doesn't properly install or resolve packages.

For errors like Error: Cannot find module 'uriTemplate.js', try the --experimental-vm-modules flag:

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "--node-options=--experimental-vm-modules", "@upstash/context7-mcp@1.0.6"]
    }
  }
}

Use the --experimental-fetch flag to bypass TLS-related problems:

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "--node-options=--experimental-fetch", "@upstash/context7-mcp"]
    }
  }
}

1. Try adding @latest to the package name
2. Use bunx as an alternative to npx
3. Consider using deno as another alternative
4. Ensure you're using Node.js v18 or higher for native fetch support
