intesta-mcp

An MCP server that lets an AI agent check who it is dealing with before it acts.

Intesta is a trust registry. Every entity has a trust level on the A0→A4 ladder (A0 claimed · A1 domain-control · A2 payment-verified · A3/A4 higher) and a set of facts, each marked confirmed (independently verified) or auto_collected (scraped from public sources, not verified). This server exposes the registry's public reads as MCP tools so an agent can ask "can I trust this domain, and what is actually proven?" before it pays a counterparty, shares data, or follows instructions from an unknown party.

Its ethos is Intesta's own: refuse, don't guess. A level is only ever what was proven; an auto_collected fact is not a verified one. The server reports exactly what the registry says and never upgrades either.

Tools

All tools are read-only and need no API key — public registry reads work out of the box. An optional INTESTA_API_KEY (ik_…) is only needed for metered or private use.

Install

// Claude Desktop / any MCP client — mcp config
{
  "mcpServers": {
    "intesta": { "command": "uvx", "args": ["intesta-mcp"] }
  }
}

Or run directly:

uvx intesta-mcp

Example

Agent is about to send funds to acme-invoicing.com.

check_trust("acme-invoicing.com")
→ { "level": "A0", "attested": false,
    "what_is_proven": "listed only; nothing independently verified" }

A0 and attested:false means the domain is unproven — the agent should pause or escalate (pair this with Raposa Aval for a human approval step) rather than assume the counterparty is who it claims to be.
