npm install @iflow-mcp/context7Context7 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LLMs rely on outdated or generic information about the libraries you use.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- ❌ Code examples are outdated and based on year-old training data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:
``txt/login
Create a Next.js middleware that checks for a valid JWT in cookies and redirects unauthenticated users to . use context7`
`txt`
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No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.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.

}
}
}
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
`json`
{
"mcpServers": {
"context7": {
"url": "https://mcp.context7.com/mcp"
}
}
}
#### Trae Local Server Connection
`json`
{
"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
`json`
{
"mcpServers": {
"context7": {
"command": "bunx",
"args": ["-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY"]
}
}
}
#### Deno
`json`
{
"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
`Dockerfile
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:
`bash`
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:_
`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.
`json`
{
"mcpServers": {
"github.com/upstash/context7-mcp": {
"command": "cmd",
"args": ["/c", "npx", "-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY"],

🔨 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
$3
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 fileCursor Settings > Rules
- For Cursor, from sectionCLAUDE.md
- For Claude Code, in file
Or the equivalent in your MCP client to auto-invoke Context7 on any code question.
#### Example Rule
`txt`
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.
$3
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.
`txt`
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.
$3
If you are behind an HTTP proxy, Context7 uses the standard https_proxy / HTTPS_PROXY environment variables.
💻 Development
Clone the project and install dependencies:
`bash`
bun i
Build:
`bash`
bun run build
Run the server:
`bash`
bun run dist/index.js
$3
context7-mcp accepts the following CLI flags:
- --transport – Transport to use (stdio by default). Note that HTTP transport automatically provides both HTTP and SSE endpoints.--port
- – Port to listen on when using http transport (default 3000).--api-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:
`bash`
bun run dist/index.js --transport http --port 8080
Another example with stdio transport:
`bash`
bun run dist/index.js --transport stdio --api-key YOUR_API_KEY
$3
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:
`bash`.env
CONTEXT7_API_KEY=your_api_key_here
Example MCP configuration using environment variable:
`json`
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "@upstash/context7-mcp"],
"env": {
"CONTEXT7_API_KEY": "YOUR_API_KEY"
}
}
}
}
Local Configuration Example
`json`
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["tsx", "/path/to/folder/context7/src/index.ts", "--api-key", "YOUR_API_KEY"]
}
}
}
Testing with MCP Inspector
`bash`
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:
`json`
{
"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:
`json`
{
"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:
`json`
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "--node-options=--experimental-fetch", "@upstash/context7-mcp"]
}
}
}
