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.

Scored across 2 tools
The two tools have distinct purposes: market_query retrieves intelligence data, while generate_report exports a report based on that data. There is no overlap, making them easy to distinguish.
Both tool names follow a consistent verb_noun pattern with lowercase and underscores (market_query, generate_report). The naming style is uniform and predictable.
With only 2 tools for a market intelligence platform covering multiple sources, the tool count feels insufficient. A minimum of 3-5 tools would better cover typical workflows like saving or filtering queries.
The tools cover querying and report generation, which forms a basic workflow. However, there are notable gaps: no tools for saving queries, viewing past results, or managing data, limiting the agent's ability to perform iterative analysis.
