Foundersignal

Overview

Foundersignal is a Model Context Protocol server that helps you discover SaaS ideas worth building by aggregating revenue data, growth signals, and pain points from over 10 sources. Any MCP-compatible AI assistant can call Foundersignal's tools directly, letting the model decide when to use them during conversations or agent runs.

The server runs locally via the npm package foundersignal-mcp, which communicates over stdio on your machine. No authentication or credentials are required—it works immediately after installation. The latest release is v0.1.0, and the source code is available at carlosalvite/foundersignal-mcp on GitHub.

Foundersignal is categorized as Development on mcp.site and integrates with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, you're invited to claim this listing to verify ownership and keep information up to date.
