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LLMs rely on outdated or generic information about the libraries you use.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• ❌ Code examples are outdated and based on year-old training data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 that 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 Next.js middleware that checks for a valid JWT in cookies
and redirects unauthenticated users to `/login`. use context7

Configure a Cloudflare Worker script to cache
JSON API responses for five minutes. 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No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.

[!NOTE] This repository hosts the source code of Context7 MCP server. The supporting components — API backend, parsing engine, and crawling engine — are private and not part of this release.

      "command": ["npx", "-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY"],
      "enabled": true
    }
  }
}

See OpenAI Codex for more information.

Add the following configuration to your OpenAI Codex MCP server settings:

Local Server Connection

[mcp_servers.context7]
args = ["-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY"]
command = "npx"
startup_timeout_ms = 20_000

Remote Server Connection

[mcp_servers.context7]
url = "https://mcp.context7.com/mcp"
http_headers = { "CONTEXT7_API_KEY" = "YOUR_API_KEY" }

Optional troubleshooting — only if you see startup "request timed out" or "not found program". Most users can ignore this.

• First try: increase startup_timeout_ms to 40_000 and retry.
• Windows quick fix (absolute npx path + explicit env):

tomlCopy

[mcp_servers.context7]
command = "C:\\Users\\yourname\\AppData\\Roaming\\npm\\npx.cmd"
args = [
  "-y",
  "@upstash/context7-mcp",
  "--api-key",
  "YOUR_API_KEY"
]
env = { SystemRoot="C:\\Windows", APPDATA="C:\\Users\\yourname\\AppData\\Roaming" }
startup_timeout_ms = 40_000

• macOS quick fix (use Node + installed package entry point):

tomlCopy

[mcp_servers.context7]
command = "/Users/yourname/.nvm/versions/node/v22.14.0/bin/node"
args = ["/Users/yourname/.nvm/versions/node/v22.14.0/lib/node_modules/@upstash/context7-mcp/dist/index.js",
  "--transport",
  "stdio",
  "--api-key",
  "YOUR_API_KEY"
]

Notes: Replace yourname with your OS username. Explicitly setting APPDATA and SystemRoot is essential because these are required by npx on Windows but not set by certain versions of OpenAI Codex mcp clients by default.

Use the Add manually feature and fill in the JSON configuration information for that MCP server. For more details, visit the Trae documentation.

Trae Remote Server Connection

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

Trae Local Server Connection

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

Use these alternatives to run the local Context7 MCP server with other runtimes. These examples work for any client that supports launching a local MCP server via command + args.

Bun

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

Deno

{
  "mcpServers": {
    "context7": {
      "command": "deno",
      "args": [
        "run",
        "--allow-env=NO_DEPRECATION,TRACE_DEPRECATION",
        "--allow-net",
        "npm:@upstash/context7-mcp"
      ]
    }
  }
}

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):

   DockerfileCopy

   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:

   bashCopy

   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:

   jsonCopy

   {
     "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.

Install the context7.mcpb file under the mcpb folder and add it to your client. For more information, please check out MCP bundles docs.

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.

droid mcp add context7 https://mcp.context7.com/mcp --type http

Factory Local Server Connection (Stdio)

Run this command in your terminal:

droid mcp add context7 "npx -y @upstash/context7-mcp" --env CONTEXT7_API_KEY=YOUR_API_KEY

Once configured, Context7 tools will be available in your droid sessions. Type /mcp within droid to manage servers, authenticate, and view available tools.

🔨 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 5000): Max number of tokens to return. Values less than 1000 are automatically increased to 1000.

🛟 Tips

Add a Rule

If you don’t want to add use context7 to every prompt, you can define a simple rule in your MCP client's rule section:

• For Windsurf, in .windsurfrules file
• For Cursor, from Cursor Settings > Rules section
• For Claude Code, in CLAUDE.md file

Or the equivalent in your MCP client to auto-invoke Context7 on any code question.

Example Rule

Always use context7 when I need code generation, setup or configuration steps, or
library/API documentation. This means you should automatically use the Context7 MCP
tools to resolve library id and get library docs without me having to explicitly ask.

From then on, you’ll get Context7’s docs in any related conversation without typing anything extra. You can alter the rule to match your use cases.

Use Library Id

If you already know exactly which library you want to use, add its Context7 ID to your prompt. That way, Context7 MCP server can skip the library-matching step and directly continue with retrieving docs.

Implement basic authentication with Supabase. use library /supabase/supabase for API and docs.

The slash syntax tells the MCP tool exactly which library to load docs for.

HTTPS Proxy

If you are behind an HTTP proxy, Context7 uses the standard https_proxy / HTTPS_PROXY environment variables.

💻 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> – Transport to use (stdio by default). Use http for remote HTTP server or stdio for local integration.
• --port <number> – Port to listen on when using http transport (default 3000).
• --api-key <key> – API key for authentication (or set CONTEXT7_API_KEY env var). You can get your API key by creating an account at context7.com/dashboard.

Example with HTTP transport and port 8080:

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

Another example with stdio transport:

bun run dist/index.js --transport stdio --api-key YOUR_API_KEY

Environment Variables

You can use the CONTEXT7_API_KEY environment variable instead of passing the --api-key flag. This is useful for:

• Storing API keys securely in .env files
• Integration with MCP server setups that use dotenv
• Tools that prefer environment variable configuration

Note: The --api-key CLI flag takes precedence over the environment variable when both are provided.

Example with .env file:

# .env
CONTEXT7_API_KEY=your_api_key_here

Example MCP configuration using environment variable:

{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@upstash/context7-mcp"],
      "env": {
        "CONTEXT7_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

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

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
