Melt MCP Server Tools (3)
melt_analyze_value_vectors
Free Stage-1 Sandbox estimator. Estimates where value is leaking in one department from headcount, labor cost, and dominant unstructured-input type. No integration required — synthetic/self-reported inputs only.
melt_estimate_annual_leak
Quantifies an already-identified leak pattern in dollars/yr — `totalVolume x (leakRatePct/100) x valuePerEvent`, generalizing Melt's real "Anatomy of a Scan" methodology (a 29% Gong bypass rate, a 62% Clari override rate, etc., combined into a real $77,235/yr finding).
melt_request_scan
Lead-capture handoff — the move from a directional estimate to a real, log-verified scan (Frictionless POC Playbook Stage 1 → 2). Routes to HubSpot if `HUBSPOT_PORTAL_ID`/`HUBSPOT_FORM_ID` are set, otherwise appends to a local `leads.jsonl`.
