Connect an agent to the MCP server or make your first REST call in under two minutes. No API key, no signup.
The endpoint speaks Streamable HTTP at https://www.founder.best/api/mcp. It is hosted and stateless: there is nothing to install from npm and nothing to run locally.
claude mcp add --transport http founder-best https://www.founder.best/api/mcpEvery client is covered on Install the MCP server.
Ask your agent to list its tools. You should see seven, none of which need credentials:
search_products, get_product, search_founders, get_founder, get_launches, get_trending_products, search_categoriesReads need no connection, so this works immediately:
Find me 10 SaaS products for generating social media content, and tell me which ones have a free tier.Under the hood the agent calls search_products with { query: "generate social media content", limit: 10 }, then get_product for the ones it wants to describe in detail. Each result carries the Founder.best page URL and the product’s website for citations.
The REST API mirrors the tools one-to-one. No token, no header beyond an optional User-Agent.
