{"slug": "i-built-a-no-code-backend-that-gives-ai-agents-an-mcp-tool-for-real-business", "title": "I built a no-code backend that gives AI agents an MCP tool for real business logic", "summary": "A developer built Calamo, a no-code backend that lets users define Postgres tables and workflows visually, then publish them as MCP tools or REST endpoints for AI agents. The tool aims to bridge the gap between raw database access and real business logic, allowing agents to perform actions like checking inventory or processing orders without writing server code.", "body_md": "I kept running into the same annoyance building agent side projects: giving an agent DB access is easy, but the moment it needs real business logic — check inventory,\n\nprocess an order, apply a rule — I was back to writing and hosting a small server just for that one action.\n\nSo I built **Calamo**: you define objects (Postgres tables) and actions (workflows)\n\nvisually, then publish an action as an MCP tool your agent can call directly, or as a\n\nplain REST endpoint if you'd rather call it from regular code.\n\n[https://www.youtube.com/watch?v=6l4rlK88wrg](https://www.youtube.com/watch?v=6l4rlK88wrg)\n\nIn the video: I create an object, build a query action, publish it as an MCP tool,\n\nand connect it to Claude — which calls the tool live and returns real data. No\n\nservers, no code.\n\nMost tools that give agents database access (Supabase's MCP server, for example)\n\nstick to raw SQL — this is meant for the layer above that.\n\nIt's live at [calamo.dev](https://calamo.dev). Mostly curious if this is solving a real problem for people\n\nbuilding agent workflows, or if I'm missing something obvious — feedback (and skepticism) welcome.", "url": "https://wpnews.pro/news/i-built-a-no-code-backend-that-gives-ai-agents-an-mcp-tool-for-real-business", "canonical_source": "https://dev.to/rubens_rafael_700/i-built-a-no-code-backend-that-gives-ai-agents-an-mcp-tool-for-real-business-logic-3ei5", "published_at": "2026-07-08 19:46:18+00:00", "updated_at": "2026-07-08 20:11:36.903654+00:00", "lang": "en", "topics": ["ai-agents", "developer-tools", "ai-infrastructure"], "entities": ["Calamo", "Claude", "Supabase", "Postgres"], "alternates": {"html": "https://wpnews.pro/news/i-built-a-no-code-backend-that-gives-ai-agents-an-mcp-tool-for-real-business", "markdown": "https://wpnews.pro/news/i-built-a-no-code-backend-that-gives-ai-agents-an-mcp-tool-for-real-business.md", "text": "https://wpnews.pro/news/i-built-a-no-code-backend-that-gives-ai-agents-an-mcp-tool-for-real-business.txt", "jsonld": "https://wpnews.pro/news/i-built-a-no-code-backend-that-gives-ai-agents-an-mcp-tool-for-real-business.jsonld"}}
