Context7
Byupstash·32,842
Get up-to-date, version-specific documentation and code examples from any library or framework.
LLMs rely on outdated or generic information about the libraries you use.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- ❌ Code examples are outdated and based on year-old training data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
Context7 MCP pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt.
Adduse 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No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.
Check out ourproject addition guide to learn how to add (or update) your favorite libraries to Context7.
- Node.js >= v18.0.0
- Cursor, Claude Code, VSCode, Windsurf or another MCP Client
- Context7 API Key (Optional) for higher rate limits and private repositories (Get yours by creating an account atcontext7.com/dashboard)

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"
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.
On MacOS, some users may encounter the same request timed out errors like Windows,it also can be solved tith the full path to Node.js and the installed package:
[mcp_servers.context7]command ="/Users/yourname/.nvm/versions/node/v22.14.0/bin/node"# Node.js full pathargs = ["/Users/yourname/.nvm/versions/node/v22.14.0/lib/node_modules/@upstash/context7-mcp/dist/index.js","--transport","stdio","--api-key","YOUR_API_KEY"]
This ensures Codex CLI works reliably on MacOS.

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-alpineWORKDIR /app# Install the latest version globallyRUN npm install -g @upstash/context7-mcp# Expose default port if needed (optional, depends on MCP client interaction)# EXPOSE 3000# Default command to run the serverCMD ["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 theDockerfile
: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
vsservers
). Also, ensure the image name inargs
matches the tag used during thedocker build
command.

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.
If you don’t want to adduse 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.
Always use context7 when I need code generation, setup or configuration steps, orlibrary/API documentation. This means you should automatically use the Context7 MCPtools 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.
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.
If you are behind an HTTP proxy, Context7 uses the standardhttps_proxy
/HTTPS_PROXY
environment variables.
Clone the project and install dependencies:
bun i
Build:
bun run build
Run the server:
bun run dist/index.js
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 usinghttp
transport (default3000
).--api-key <key>
– API key for authentication (or setCONTEXT7_API_KEY
env var). You can get your API key by creating an account atcontext7.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
You can use theCONTEXT7_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:
# .envCONTEXT7_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" } } }}
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
Module Not Found Errors
If you encounterERR_MODULE_NOT_FOUND
, try usingbunx
instead ofnpx
:
{"mcpServers": {"context7": {"command":"bunx","args": ["-y","@upstash/context7-mcp"] } }}
This often resolves module resolution issues in environments wherenpx
doesn't properly install or resolve packages.
ESM Resolution Issues
For errors likeError: 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": {"command":"npx","args": ["-y","--node-options=--experimental-fetch","@upstash/context7-mcp"] } }}
General MCP Client Errors
- Try adding
@latest
to the package name - Use
bunx
as an alternative tonpx
- Consider using
deno
as another alternative - Ensure you're using Node.js v18 or higher for native fetch support
