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LLMs rely on outdated or generic information about the libraries you use.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- ❌ Code examples are outdated and based on year-old training data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 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 basic Next.js project with app router. use context7
Create a script to delete the rows where the city is "" given PostgreSQL credentials. 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No tab-switching, no hallucinated APIs that don't exist, no outdated code generations.
📚 Adding Projects
Check out our project addition guide to learn how to add (or update) your favorite libraries to Context7.
🛠️ Installation
Requirements
- Node.js >= v18.0.0
- Cursor, Windsurf, Claude Desktop or another MCP Client
bash
npx -y @smithery/cli@latest install @upstash/context7-mcp --client <CLIENT_NAME> --key <YOUR_SMITHERY_KEY>
You can find your Smithery key in the Smithery.ai webpage.
Settings
-> Cursor Settings
-> MCP
-> Add new global MCP server
Pasting the following configuration into your Cursor ~/.cursor/mcp.json
file is the recommended approach. You may also install in a specific project by creating .cursor/mcp.json
in your project folder. See Cursor MCP docs for more info.
> Since Cursor 1.0, you can click the install button below for instant one-click installation.

}
json
{

}
}
}
Once saved, enter in the chat get-library-docs
followed by your Context7 documentation ID (e.g., get-library-docs /nuxt/ui
). More information is available on BoltAI's Documentation site. For BoltAI on iOS, see this guide.
Dockerfile
in the project root (or anywhere you prefer):
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
:
docker build -t context7-mcp .
Configure Your MCP Client:
Update your MCP client's configuration to use the Docker command.
_Example for a cline_mcpsettings.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.
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@latest"],
"disabled": false,
"autoApprove": []
}
}
}
mcpServers
array in the augment.advanced
object
json
"augment.advanced": {
"mcpServers": [
{
"name": "context7",
"command": "npx",
"args": ["-y", "@upstash/context7-mcp"]
}
]
}
Once the MCP server is added, restart your editor. If you receive any errors, check the syntax to make sure closing brackets or commas are not missing.
json
{
"mcpServers": {
"context7": {
"type": "streamable-http",
"url": "https://mcp.context7.com/mcp"
}
}
}
#### Roo Code Local Server Connection
json
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "@upstash/context7-mcp"]
}
}
}
json
{
"command": "npx",
"args": [
"-y",
"@upstash/context7-mcp@latest"
]
}
Once the MCP server is added, you can easily continue using it.

"args": ["-y", "@upstash/context7-mcp@latest"]

🔨 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 10000): Max number of tokens to return. Values less than the default value of 10000 are automatically increased to 10000.
💻 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|sse>
– Transport to use (stdio
by default).--port <number>
– Port to listen on when usinghttp
orsse
transport (default3000
).
Example with http transport and port 8080:
bun run dist/index.js --transport http --port 8080
json
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["tsx", "/path/to/folder/context7-mcp/src/index.ts"]
}
}
}
bash
npx -y @modelcontextprotocol/inspector npx @upstash/context7-mcp
🚨 Troubleshooting
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.
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"]
}
}
}
--experimental-fetch
flag to bypass TLS-related problems:
json
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "--node-options=--experimental-fetch", "@upstash/context7-mcp"]
}
}
}
@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
