Ask Claude what to build. Get ranked opportunities backed by real market data.
FounderSignal is an MCP server that connects Claude (and any MCP-compatible AI client) to curated market intelligence — revenue figures, growth signals, competition analysis and community pain points aggregated from the platforms founders actually use.
Instead of spending a Saturday copy-pasting data from AppSumo, TrustMRR, Reddit, Google, or Product Hunt into a spreadsheet, you just ask.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
