Coolify is the open-source, self-hostable alternative to Heroku, Netlify, and Vercel — used by developers who want platform-as-a-service without the platform lock-in. io.github.StuMason/coolify now lets you manage it through Claude.
The Server
Built by Stu Mason (GitHub, Folkestone, UK), coolify-mcp exposes 38 tools across infrastructure management, diagnostics, batch operations, servers, projects, applications, databases, services, deployments, environment variables, and documentation search. The README describes it as:
"The most comprehensive MCP server for Coolify — 38 optimized tools, smart diagnostics, documentation search, and batch operations for managing your self-hosted PaaS through AI assistants."
— coolify-mcp README
The design philosophy centers on token efficiency. Rather than creating one tool per CRUD operation per resource — which would produce dozens of tools with redundant descriptions — Mason consolidated related operations into single tools with action parameters. The result:
"The server uses 85% fewer tokens than a naive implementation (6,600 vs 43,000) by consolidating related operations into single tools with action parameters. This prevents context window exhaustion in AI assistants."
— coolify-mcp README
Response-level reductions are even larger: application listings go from ~170KB raw to ~4.4KB summarized (97% reduction), and service listings from ~367KB to ~1.2KB (99%). The server also supports smart lookups by domain, name, or IP — not just UUID — and returns HATEOAS-style actions suggesting what the agent can do next.
The Platform It Wraps
Coolify has built a passionate community of self-hosters who want the deployment experience of Vercel without sending their code or data to a third party. It handles Docker, Docker Compose, and Nixpacks deployments across multiple servers. The MCP server covers the full surface: creating and managing projects, deploying applications, provisioning databases (8 types), managing environment variables in bulk, and searching Coolify's documentation. The use case is natural: "deploy my app to staging, check the logs, roll back if something breaks" — all through conversation.
