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LLMs rely on outdated or generic information about the libraries you use.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❌ Code examples are outdated and based on year-old training data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No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.

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.

      "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:

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 .
```
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 command and args.

🔨 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). Note that HTTP transport automatically provides both HTTP and SSE endpoints.
--port <number> – Port to listen on when using http transport (default 3000).
--api-key <key> – API key for authentication. 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

Local Configuration Example

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

Testing with MCP Inspector

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

🚨 Troubleshooting

Module Not Found Errors

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.

ESM Resolution Issues

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"]
    }
  }
}

TLS/Certificate Issues

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

{
  "mcpServers": {

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.

    }
  }
}

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:

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 .
```
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.

🔨 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

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). Note that HTTP transport automatically provides both HTTP and SSE endpoints.
--port <number> – Port to listen on when using http transport (default 3000).
--api-key <key> – API key for authentication. 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

Local Configuration Example

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

Testing with MCP Inspector

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

🚨 Troubleshooting

Module Not Found Errors

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.

ESM Resolution Issues

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

{
  "mcpServers": {
    "context7": {
      "command": "npx",
