What is MCP?

The Model Context Protocol (MCP) is an open standard that lets AI assistants (Claude, ChatGPT and others) safely use external tools. Hadaly's MCP server exposes our valuation engine: your AI agent can call the valuation tool and receive a valuation range without leaving the conversation.

Why connect it

Real-time valuation

An enterprise-value estimate computed from 100,000+ comparable transactions.

Works with any agent

Works with Claude Desktop, MCP clients, and any agent that speaks the MCP JSON-RPC protocol.

Secure by design

Strict rate limits, input validation, and no personal data required for an estimate.

The available tool

evaluate_business

Estimates the enterprise value of an SME from a few key inputs. Returns an indicative valuation range.

  • nombreEmployesNumber of employees (1 to 10,000)required
  • dateFondationYear founded (e.g. 2015) — optional if detectable from siteWebrequired*

* Provide either secteur or siteWeb: if you give the website URL, the sector (and founding year if missing) is detected automatically by Hadaly's AI. An explicitly provided sector always takes priority.

Limits & security

The server is public but protected against abuse:

  • Rate limit: 60 requests per minute per IP address.
  • Valuation limit: 15 tool calls per hour per IP address.
  • Strict validation of all inputs (types, bounds, allowed sectors).
  • Request size capped and batch requests rejected.
  • No personal data is required or stored for an estimate.

Estimates returned by the MCP server are indicative and do not replace a professional valuation.
