The Preuve AI startup validation API lets any AI agent validate startup ideas programmatically. The Agent API and its MCP server are live. The remote MCP server at https://mcp.preuve.ai/mcp works as a claude.ai custom connector with OAuth sign-in, or with Claude Code, Cursor, Codex, Hermes Agent, and any HTTP MCP client; a local stdio server is also available. The API runs the Preuve analysis and returns a viability score, market research, competitor analysis, a structured ideas-json export, and a shareable report URL. Deep reports can generate optional modules: Proof of Demand, Founder Fit, Playbook, Trends, and Community Signals. A ready-made Agent Skill at docs.preuve.ai/agent-skill teaches AI agents the full Preuve workflow, including quota safety and retry semantics. API keys never grant access to the Preuve dashboard or account settings.

Startup validation API FAQ

It is an HTTP API that runs a Preuve analysis on a startup idea and returns a viability score, market research, competitor analysis, a shareable report URL, and a structured JSON export. You authenticate each request with a single API key header, so any AI agent, CLI, or backend script can validate ideas programmatically.
