HasMCP-CE

HasMCP is a tool that converts API endpoints into MCP Server without writing a single line of code. It is practical alternative for developers and SaaS owners who prefers not to develop anad maintain MCP spec changes over time.

HasMCP-CE shares the some logic for the commercial versions of the HasMCP-Pro and HasMCP-Enterprise.

NOTE: HasMCP-Pro and HasMCP-Enterprise versions are maintained in private repositories and source codes are not available. HasMCP Cloud service itself uses the HasMCP-Enterprise edition on production.

HasMCP-CE Features

• Automated MCP server creation using OpenAPI Spec v3+ and Swagger

• Oauth2 authentication

• Manual MCP from API endpoints

• Toggle endpoints per MCP Server

• Proxy headers (optional per MCP Server) to actual API endpoints

• Long term, short-term authentication tokens per MCP Server

• Real-time MCP Server method/tool call logs

• Real-time MCP server analytics (added in v0.2.2)

• Optional automated SSL with Let's encrypt

HasMCP Cloud Features

Cloud version is available with Hobby(with monthly free-tier) and Pro subscriptions at hasmcp.com. It has some additonal features compared to the Community Edition:

• Request/response payload optimization per tool with a minimum coding (interceptors). Up to 98% token reduction on MCP tool responses (depending on what is needed by the described tool).
• Per tool call, per user usage analytics
• Users, teams management (Pro and Enterprise only)
• Audit logs (Enterprise only)

Why does it have cloud version?

• To support futher development
• Help developers and companies those are not interested in running a server and maintain it
• Entrepreneurship

Development

HasMCP-CE is using monorepo approach that hosts both frontend and backend codes in the same repository.

Directory Structure

hasmcp-ce
|- backend            # backend for hasmcp-ce
|- frontend           # front-end for hasmcp-ce
|- COMMERCIAL_LICENSE # Commercial license
|- Dockerfile         # Dockerfile
|- LICENSE            # License file
|- Makefile           # Handy Make commands to help developers
|- README.md          # The current file that you are reading now

Development environment requires 2 services up and running at the same time:

1. Frontend

cd frontend
npm run dev # this will open port 5173

1. Backend

cd backend/cmd/server
go run main.go

1. Database

By default hasmcp-ce uses sqlite so you don't need to do anything. It is more than enough for single user experience.

To enable Postgres instead of Sqlite, you can add the following to the your .env file

POSTGRES_ENABLED=false # set true to use postgres as production db

# below are the your db connection details for postgres
POSTGRES_TIMEZONE=UTC
POSTGRES_USER=postgres
POSTGRES_PASSWORD=postgres
POSTGRES_HOST=localhost
POSTGRES_PORT=5432
POSTGRES_DBNAME=postgres

Running the HasMCP-CE with Docker (recommended)

The recommended way of running HasMCP-CE version using docker. Please do not confuse using docker does not mean that using the latest version. The following example is using the latest version, please adjust the version and changes based on your needs!

Setup

Apply both One time setup and Configurations for the first run then you can use only Configurations section.

One time setup

mkdir hasmcp
cd hasmcp
mkdir -p _certs _storage # creates folders
chmod 0777 _certs
chmod 0777 _storage

.env file

.env overrides the default configurations. It is highly recommended to use .env constants to set the values to your desired values.

cd hasmcp # if you are not in this folder yet (if you continue from the previous step you should be inside this folder already)
wget https://github.com/hasmcp/hasmcp-ce/blob/main/backend/cmd/server/.env.example -O .env

After downloading the example .env file, edit the content as you wish.

Run

Latest version:

docker stop hasmcp-ce || true; \
	docker rm hasmcp-ce || true; \
	docker image prune -f; \
	docker pull hasmcp/hasmcp-ce:latest; \
	docker run --env-file .env -p 80:80 -p 443:443 --name hasmcp-ce \
    -v ./_certs:/_certs \
    -v ./_storage:/_storage \
    -d --restart always hasmcp/hasmcp-ce:latest

Other known versions for example v0.2.3:

HASMCP_VERSION=v0.2.3 \
  docker stop hasmcp-ce || true; \
  docker rm hasmcp-ce || true; \
  docker image prune -f; \
  docker pull hasmcp/hasmcp-ce:$HASMCP_VERSION; \
  docker run --env-file .env -p 80:80 -p 443:443 \
    --name hasmcp-ce \
    -v ./_certs:/_certs \
    -v ./_storage:/_storage \
    -d \
    --restart always \
    hasmcp/hasmcp-ce:$HASMCP_VERSION
