Founders OS – open-source MCP server that gives AI your business context

Founders OS, an open-source MCP server, provides 92 tools across 12 modules to give AI assistants like Claude and Cursor business context from CRM, projects, finances, and memory, eliminating the need to re-explain company operations. The MIT-licensed toolkit connects to a Supabase database and is designed for non-developers with a three-step setup process.

Open-Source MCP Toolkit Stop re-explaining your business to your AI. FoundersOS remembers how your company runs, so your AI doesn't have to ask. It connects your CRM, projects, tasks, finances, playbooks, memory, and feeds directly to Claude, Cursor, or any MCP-compatible AI. Stop copy-pasting. Start actually working. To get the most out of FoundersOS, we recommend Read This First /docs/read-this-first - five minutes on what these tools can and can't do. What's in the box 92 tools, one connection Twelve modules, all plugged into your AI through a single MCP connection. No dashboards to learn. Just talk. CRM Customers, contacts, interactions, and a live pipeline dashboard. Track every relationship through conversation. Tasks Create, assign, link, and complete tasks with dependencies, entity linking, AI assignment, and progress notes. Projects First-class project records anchored on a project tag, with task rollups grouped by status. Playbooks Reusable orchestration templates that fan out to tasks and external MCP actions in one run. Tags A shared vocabulary with auto-registration, typo detection, and soft validation that never blocks you. Financial Double-entry ledger with categories, accounts, transfers, P&L, multi-company, and per-user access control. Feeds RSS, Atom, and JSON feeds with AI briefings, bookmarks, and pins. Stay informed without doomscrolling. Memory Semantic memory powered by pgvector with personal and org scopes, dedup, and natural-language recall. Surfaces Cross-domain views: session-start dashboard, entity cards, weekly retros, and stuck lists. Members Org membership directory that maps user IDs to names and designates the company owner. Audit + Restore A full audit trail across every domain, plus one-call recovery of any soft-deleted record. Diagnostics Ping, version, usage guide, capability explorer, and bundled interactive walkthroughs. The 60-second overview Three steps. That's it. Set up a Supabase project Free tier works great. Create a project, then paste one SQL file the consolidated schema into the SQL editor. The setup wizard prints it for you. Add one block to your AI config Paste this in and fill your Supabase and embedding keys into the env block - or let the setup wizard /setup/ generate the whole thing for you. { "mcpServers": { "founders-os": { "command": "npx", "args": "-y", "@ourthinktank/founders-os@latest" , "env": { "SUPABASE URL": "https://...", "SUPABASE SECRET KEY": "sb secret ...", "OPENAI API KEY": "sk-..." } } } } The @latest tag keeps you current: each time you restart your AI, it pulls the newest version automatically. Drop it to pin a fixed version instead. Talk to your AI like it knows your business "Add Acme Corp as a new prospect." "What's overdue? What's falling through the cracks?" "Run the customer-onboarding playbook for Acme." "Show me the P&L for last quarter." "Remember: we're targeting SMB fintech in Q3."
