Track what 1,000+ VCs follow on X to surface startups before their round. Signal for AI agents.
Most developer tooling work still happens through a UI a human drives. Frontrun MCP server moves it into the conversation instead. Track what 1,000+ VCs follow on X to surface startups before their round. Signal for AI agents.
VC follow intelligence for AI agents. Track what top investors follow on X — detect new follows, convergence signals, and trending companies before they're announced.
The server publishes 7 tools. What each one is for:
macOS — ~/Library/Application Support/Claude/claude_desktop_config.jsonWindows — %APPDATA%\Claude\claude_desktop_config.jsonDiscovery — The Discovery tool exposed by this serverTracking — The Tracking tool exposed by this serverSignals — The Signals tool exposed by this serverClassification — The Classification tool exposed by this serverWebhooks — The Webhooks tool exposed by this serverBecause this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Configuration is passed through the environment: FRONTRUN_API_KEY, FR_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Frontrun's toolset — macOS, Windows, Discovery and 4 more — is a fair guide to whether it matches your workflow. It is maintained by jongall45; worth a glance at recent repository activity before you build anything load-bearing on it.
