# MCP Registry
A community driven registry service for Model Context Protocol (MCP) servers.
## Development Status
This project is being built in the open and is currently in the early stages of development. Please see the [overview discussion](https://github.com/modelcontextprotocol/registry/discussions/11) for the project scope and goals. If you would like to contribute, please check out the [contributing guidelines](CONTRIBUTING.md).
## Overview
The MCP Registry service provides a centralized repository for MCP server entries. It allows discovery and management of various MCP implementations with their associated metadata, configurations, and capabilities.
## Features
- RESTful API for managing MCP registry entries (list, get, create, update, delete)
- Health check endpoint for service monitoring
- Support for various environment configurations
- Graceful shutdown handling
- MongoDB and in-memory database support
- Comprehensive API documentation
- Pagination support for listing registry entries
## Getting Started
### Prerequisites
- Go 1.18 or later
- MongoDB
- Docker (optional, but recommended for development)
## Running
The easiest way to get the registry running is to use `docker compose`. This will setup the MCP Registry service, import the seed data and run MongoDB in a local Docker environment.
```bash
# Build the Docker image
docker build -t registry .
# Run the registry and MongoDB with docker compose
docker compose up
```
This will start the MCP Registry service and MongoDB with Docker, exposing it on port 8080.
## Building
If you prefer to run the service locally without Docker, you can build and run it directly using Go.
```bash
# Build a registry executable
go build ./cmd/registry
```
This will create the `registry` binary in the current directory. You'll need to have MongoDB running locally or with Docker.
By default, the service will run on `http://localhost:8080`.

## API Documentation
The API is documented using Swagger/OpenAPI. You can access the interactive Swagger UI at:
```
/v0/swagger/index.html
```
This provides a complete reference of all endpoints with request/response schemas and allows you to test the API directly from your browser.
## API Endpoints
### Health Check
```
GET /v0/health
```
Returns the health status of the service:
```json
{
"status": "ok"
}
```
### Registry Endpoints
#### List Registry Server Entries
```
GET /v0/servers
```
Lists MCP registry server entries with pagination support.
Query parameters:
- `limit`: Maximum number of entries to return (default: 30, max: 100)
- `cursor`: Pagination cursor for retrieving next set of results
Response example:
```json
{
"servers": [
{
"id": "1",
"name": "Example MCP Server",
"description": "An example MCP server implementation",
"url": "https://example.com/mcp",
"repository": {
"url": "https://github.com/example/mcp-server",
"stars": 120
},
"version": "1.0.0",
}],
"metadata": {
"next_cursor": "cursor-value-for-next-page"
}
}
```
#### Publish a Server Entry
```
POST /v0/publish
```
Publishes a new MCP server entry to the registry. Authentication is required via Bearer token in the Authorization header.
Headers:
- `Authorization`: Bearer token for authentication (e.g., `Bearer your_token_here`)
- `Content-Type`: application/json
Request body example:
```json
{
"server_detail": {
"name": "io.github.username/repository",
"description": "Your MCP server description",
"version_detail": {
"version": "1.0.0"
},
"registries": [
{
"name": "npm",
"package_name": "your-package-name",
"license": "MIT"
}
],
"remotes": [
{
"transport_type": "http",
"url": "https://your-api-endpoint.com"
}
]
},
"repo_ref": "username/repository"
}
```
Response example:
```json
{
"message": "Server publication successful",
"id": "1234567890abcdef12345678"
}
```
### Ping Endpoint
```
GET /v0/ping
```
Simple ping endpoint that returns environment configuration information:
```json
{
"environment": "dev",
"version": "registry-"
}
```
## Configuration
The service can be configured using environment variables:
| Variable | Description | Default |
|----------|-------------|---------|
| `MCP_REGISTRY_APP_VERSION` | Application version | `dev` |
| `MCP_REGISTRY_COLLECTION_NAME` | MongoDB collection name | `servers_v2` |
| `MCP_REGISTRY_DATABASE_NAME` | MongoDB database name | `mcp-registry` |
| `MCP_REGISTRY_DATABASE_URL` | MongoDB connection string | `mongodb://localhost:27017` |
| `MCP_REGISTRY_GITHUB_CLIENT_ID` | GitHub App Client ID | |
| `MCP_REGISTRY_GITHUB_CLIENT_SECRET` | GitHub App Client Secret | |
| `MCP_REGISTRY_LOG_LEVEL` | Log level | `info` |
| `MCP_REGISTRY_SEED_FILE_PATH` | Path to import seed file | `data/seed.json` |
| `MCP_REGISTRY_SEED_IMPORT` | Import `seed.json` on first run | `true` |
| `MCP_REGISTRY_SERVER_ADDRESS` | Listen address for the server | `:8080` |
## Testing
Run the test script to validate API endpoints:
```bash
./scripts/test_endpoints.sh
```
You can specify specific endpoints to test:
```bash
./scripts/test_endpoints.sh --endpoint health
./scripts/test_endpoints.sh --endpoint servers
```
