Founders OS

Open-source MCP server for startup and small business founders.

Founders OS gives you a complete business context - CRM, projects, tasks, finances, feeds, memory, playbooks - accessible from Claude, Cursor, or any MCP-compatible AI client. One connection, your entire business.

Built by OurThinkTank. Docs and setup wizard at foundersmcp.com. Source on GitHub.

92 tools across 12 modules: CRM, tasks, projects, playbooks, tags, financial ledger with P&L, RSS/Atom feeds, semantic memory (pgvector), cross-domain surfaces, members, audit + restore, and diagnostics.

Quick start

You need a Supabase project, an embedding API key (OpenAI by default), and an MCP-capable AI client.

1. Database - the wizard at foundersmcp.com/setup hands you a ready-to-run setup.sql matched to your embedding provider. Run it once in your Supabase SQL Editor.

2. Client config - the same wizard generates this filled in, or paste it into your client's mcp.json by hand:

{
  "mcpServers": {
    "founders-os": {
      "command": "npx",
      "args": ["-y", "@ourthinktank/founders-os@latest"],
      "env": {
        "SUPABASE_URL": "https://your-project.supabase.co",
        "SUPABASE_SECRET_KEY": "sb_secret_...",
        "FOUNDERS_OS_COMPANY_ID": "your-company",
        "FOUNDERS_OS_USER_ID": "your-name",
        "FOUNDERS_OS_TIMEZONE": "America/Los_Angeles",
        "EMBEDDING_PROVIDER": "openai",
        "EMBEDDING_MODEL": "text-embedding-3-small",
        "EMBEDDING_DIM": "1536",
        "OPENAI_API_KEY": "sk-..."
      }
    }
  }
}

3. Try it - restart your client and ask:

What can you do?
Catch me up
Add Acme Corp as a new prospect
Create a task to send the proposal by Friday
What's stuck or overdue?
Show me OTT's P&L for Q1

OpenAI, AWS Bedrock, and Ollama are supported as embedding providers. Full environment-variable reference, tool docs, and recipes: foundersmcp.com/docs.

Staying up to date

The get_version tool reports the running version, the latest published release, how to upgrade, and whether your database schema matches the server (with the exact migration files to run when it doesn't). Set it up as a scheduled check and forget about versions.
