Agent-ready databases and backends
We scanned 12 hosted databases and backend-as-a-service platforms the way an AI agent would, and scored how well ChatGPT, Claude and Perplexity can read each one, sign a team up and connect through the API.
Which database or backend platform is best for AI agents?
It depends on what you need agents to do. If you want an agent to sign your team up and connect through the API, Supabase scores highest (96/100), followed by Upstash (93) and Turso (91). Supabase, Upstash, Turso, Convex, Appwrite, Nhost, MongoDB and Neon run remote MCP servers agents can connect to directly. None of them blocks AI agents outright. Scores as of 3 Nov 2026.

Automated, read-only scan of each homepage, robots.txt, llms.txt, docs, OpenAPI paths and MCP endpoints on 3 Nov 2026. Score = core + the average of Sign up and API, so the two job columns share 40 points. Scores can change; use "Re-check live" for today's result. How scoring works.

Questions
Which database or backend platform is the most agent-ready?
Supabase, with 96/100 in our scan on 3 Nov 2026.
Which databases and backends block AI agents?
None of the 12 we scanned.
How is the score calculated?
Out of 100: up to 60 core points for what every site needs (agents can reach and read it, structured data, llms.txt), plus the average of two job scores, each out of 40: letting an agent sign a team up (public pricing, an open sign-up page, a free plan) and letting it connect through the API (OpenAPI, MCP, self-serve keys, OAuth self-registration). For Supabase: 58 + (36 + 40) ÷ 2, rounded, = 96.
