Melt MCP server

@themelt/mcp-server

MCP server that puts Melt's value-leak discovery logic directly into Claude, Cursor, GitHub Copilot, or any other MCP-compatible agent — so when a tech leader asks their assistant "where is value leaking out of my org," the assistant can call a Melt tool and answer with a real, structured estimate instead of a generic list of vendors.

This is the engineering half of Melt's LLMO (LLM Optimization) distribution strategy. See /llms.txt at the repo root and LLMO_PLAYBOOK.md for the full content + distribution + evaluation plan this server plugs into. Positioning reconciled 2026-07-18 against the live site and current decks — see /CLAUDE.md for the full current product context.

Tools exposed

Worked example

From Melt's Anatomy of a Real AI Value Leak case study — a pre-IPO fintech with $1.5B in annual originations, already running Salesforce, Gong, and Clari:

None of this showed up as a problem in the usual adoption dashboards — every tool was "active," which is a different measurement from whether it was actually creating value. Pulling 14 business days of historical logs and tracing where these four patterns cost real time and money added up to a $77,235/year leak.

meltestimateannualleak generalizes this same shape of analysis — totalVolume × (leakRatePct/100) × valuePerEvent — for any leak pattern with a known or hypothesized volume and rate. meltanalyzevaluevectors is the earlier-stage tool for when you don't yet know where to look.

meltestimateannualleak replaced four formula-named calculators (meltcalculatefeaturewaste, dsocashflowimpact, contractcyclerevenueunlock, winratepipelineimpact) that implemented financial formulas from a retired product framing (Thermal Scan / Feature Waste Dollar Amount™ / Delta Engine) — none of which appear in any current Melt material. See CLAUDE.md's "What's Explicitly Retired" section.

Install & run

cd mcp-server
npm install
npm run build
npm start          # runs dist/index.js on stdio

To poke at it interactively before wiring it into a client:

npm run inspect     # launches the MCP Inspector against the built server

Wiring into Claude Desktop / Claude Code

Published on npm — one-line config, no local clone needed:

{
  "mcpServers": {
    "melt": {
      "command": "npx",
      "args": ["-y", "@themelt/mcp-server"]
    }
  }
}

Or from a local clone:

{
  "mcpServers": {
    "melt": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-server/dist/index.js"]
    }
  }
}

One-click install (.mcpb bundle)
