How to Set Up and Use HasMCP CE
HasMCP Community Edition is an open-source MCP gateway and builder that turns any OpenAPI v3+ or Swagger specification into a fully authenticated MCP server in minutes, without writing code. It acts as a proxy layer that converts REST API endpoints into MCP tools, manages OAuth2 authentication tokens per server, provides real-time request logging and analytics, and automates SSL certificate provisioning via Let's Encrypt. Developers and teams use it to expose internal APIs, third-party SaaS services, or custom backends to AI agents through a unified MCP interface, with per-endpoint toggle control and short- and long-term token management. It ships as a single Docker image or can be run locally with a Go backend and a Vite/React frontend.
Prerequisites
- Docker 20+ (recommended) or Go 1.21+ and Node.js 18+ for local development
- A domain name (or localhost) for the HasMCP gateway, with ports 80 and 443 accessible for SSL automation
- OpenAPI v3+ or Swagger 2.0 specification for each API you want to expose as an MCP server
- An MCP-compatible client such as Claude Desktop, Cursor, or VS Code with Copilot
- Optional: PostgreSQL instance (SQLite is used by default)
Pull the HasMCP CE Docker image
Pull the latest community edition image from Docker Hub. You can also pin a specific version using the HASMCP_VERSION variable.
docker pull hasmcp/hasmcp-ce:latestCreate the environment file
Download the example .env file and customise it. By default, HasMCP CE uses SQLite; set POSTGRES_ENABLED=true and supply connection details to switch to PostgreSQL.
wget https://raw.githubusercontent.com/hasmcp/hasmcp-ce/main/backend/cmd/server/.env.example -O .env
# Edit .env as needed, e.g.:
# POSTGRES_ENABLED=false
# POSTGRES_USER=hasmcp
# POSTGRES_PASSWORD=secret
# POSTGRES_HOST=db
# POSTGRES_PORT=5432
# POSTGRES_DBNAME=hasmcpStart the HasMCP CE server
Run the container, mounting persistent storage for certificates and database files. The gateway listens on ports 80 and 443.
docker run --env-file .env \
-p 80:80 -p 443:443 \
-v ./_certs:/_certs \
-v ./_storage:/_storage \
-d --restart always \
hasmcp/hasmcp-ce:latestImport an OpenAPI specification
Open the HasMCP CE web UI (http://localhost or your domain), log in, and paste or upload your OpenAPI v3+ spec. HasMCP will parse each endpoint and create a corresponding MCP tool.
Configure authentication tokens
In the HasMCP CE dashboard, set per-server authentication tokens (Bearer, API key, or OAuth2). These are injected automatically into proxied requests — your MCP client never handles raw credentials.
Connect your MCP client
Add the generated MCP server URL to your client configuration. HasMCP CE exposes each imported API as a distinct MCP server endpoint.
{
"mcpServers": {
"my-api": {
"command": "npx",
"args": ["-y", "mcp-remote", "https://<your-hasmcp-domain>/sse/<server-id>"]
}
}
}HasMCP CE Examples
Client configuration (Claude Desktop via SSE)
Connect Claude Desktop to a HasMCP CE hosted MCP server using mcp-remote as the transport bridge.
{
"mcpServers": {
"hasmcp-gateway": {
"command": "npx",
"args": [
"-y",
"mcp-remote",
"https://<your-hasmcp-domain>/sse/<server-id>"
]
}
}
}Prompts to try
After importing an API spec, use prompts like these to interact with the exposed MCP tools through your AI assistant.
- "List all available tools imported from my OpenAPI spec."
- "Call the /products endpoint and return items where category is 'electronics'."
- "Show me the real-time request logs for the last 10 tool calls made through HasMCP."
- "Toggle off the DELETE /users/{id} endpoint so it can't be called by the AI agent."Troubleshooting HasMCP CE
SSL certificate provisioning fails on startup.
Ensure your domain's DNS A record points to the server's public IP and that ports 80 and 443 are open in your firewall. Let's Encrypt requires HTTP-01 challenge access on port 80 before issuing a certificate.
OpenAPI import results in missing or broken tools.
HasMCP CE requires OpenAPI v3.0+ or Swagger 2.0. Validate your spec at editor.swagger.io before import. Ensure all $ref references are resolved (use a bundled/dereferenced spec if necessary).
PostgreSQL connection refused error on startup.
If you set POSTGRES_ENABLED=true, make sure the PostgreSQL host, port, user, password, and database name in .env are correct and that the database server is running and reachable from the container network.
