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

  [-purple>)](./docs/README.pt-BR.md)        

❌ 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LLMs rely on outdated or generic information about the libraries you use.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• ❌ Code examples are outdated and based on year-old training data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No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.

Roo Code Remote Server Connection

{
  "mcpServers": {
    "context7": {

2. Add the following to the mcpServers object in your settings.json file:

{
  "mcpServers": {
    "context7": {
      "httpUrl": "https://mcp.context7.com/mcp",
      "headers": {

If the mcpServers object does not exist, create it.

Install in Claude Desktop

Remote Server Connection

Open Claude Desktop and navigate to Settings > Connectors > Add Custom Connector. Enter the name as Context7 and the remote MCP server URL as https://mcp.context7.com/mcp.

Local Server Connection

Open Claude Desktop developer settings and edit your claude_desktop_config.json file to add the following configuration. See Claude Desktop MCP docs for more info.

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

Install in Opencode

Add this to your Opencode configuration file. See Opencode MCP docs for more info.

Opencode Remote Server Connection

"mcp": {
  "context7": {
    "type": "remote",
    "url": "https://mcp.context7.com/mcp",
    "headers": {
      "CONTEXT7_API_KEY": "YOUR_API_KEY"
    },
    "enabled": true
  }
}

Opencode Local Server Connection

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

Install in OpenAI Codex

See OpenAI Codex for more information.

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

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

⚠️ Windows Notes

On Windows, some users may encounter request timed out errors with the default configuration. In that case, explicitly configure the MCP server with the full path to Node.js and the installed package:

[mcp_servers.context7]
command = "C:\\Program Files\\nodejs\\node.exe"
args = [
  "C:\\Users\\yourname\\AppData\\Roaming\\npm\\node_modules\\@upstash\\context7-mcp\\dist\\index.js",
  "--transport",
  "stdio",
  "--api-key",
  "YOUR_API_KEY"
]

Alternatively, you can use the following configuration:

[mcp_servers.context7]
command = "cmd"
args = [
    "/c",
    "npx",
    "-y",
    "@upstash/context7-mcp",
    "--api-key",
    "YOUR_API_KEY"
]
env = { SystemRoot="C:\\Windows" }
startup_timeout_ms = 20_000

This ensures Codex CLI works reliably on Windows.

      "env": {},
      "disabled": false,
      "autoApprove": []
    }
  }
}

4. Click Save to apply the changes.

Install in Trae

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"]
    }
  }
}

Using Bun or Deno

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"
      ]
    }
  }
}

Using Docker

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):

   Click to see Dockerfile content

   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.

Install Using the Desktop Extension

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

Install in Windows

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 `comman
