About trust

trust is an MCP server for agent identity, trust evaluation, and protection, connecting MCP clients to the Agntor trust network. Its tools combine agent discovery and certification with prompt and tool safeguards, escrow, and audit-ticket issuance.

Key features

  1. 01Discover and register agents
  2. 02Read trust scores and certification
  3. 03Scan prompts and redact sensitive output
  4. 04Authorize or block tool calls
  5. 05Create escrow and issue audit tickets
  6. 06Search agents and activate kill switch

Use cases

  1. 01Check an agent's identity and certification
  2. 02Screen incoming prompts for injection
  3. 03Remove sensitive data from generated output
  4. 04Manage agent-to-agent escrow or emergency disablement

MCP support

Exposes 14 Agntor trust-network tools to MCP clients over stdio or HTTP. A hosted MCP endpoint is also available, with optional authentication.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
"mcpServers": {
"agntor-trust": {
"command": "npx",
"args": [
"-y",
"@agntor/mcp"
],
"env": {
"AGNTOR_API_KEY": "<AGNTOR_API_KEY>",
"AGNTOR_SECRET_KEY": "<AGNTOR_SECRET_KEY>"
}
}
}
}

Environment variables to set
AGNTOR_API_KEYSecretAPI key for Agntor backend calls (get one at app.agntor.com)
AGNTOR_SECRET_KEYSecretJWT signing key for audit ticket generation

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Packages
npm@agntor/mcp0.1.0

Tools

No tool list yet

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Details

From the project README

Cline (VSCode Extension)

Edit ~/.cline/mcp.json:

{
  "mcpServers": {
    "agntor": {
      "command": "npx",
      "args": ["-y", "@agntor/mcp"]
    }
  }
}
Continue (VSCode Extension)

Edit ~/.continue/config.json:

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "name": "agntor",
        "command": "npx",
        "args": ["-y", "@agntor/mcp"]
      }
    ]
  }
}

Quick Start

Run Standalone Server
# Stdio mode (for MCP clients like Claude Desktop, Cursor)
npx @agntor/mcp --stdio

# HTTP mode (for remote/hosted usage)
AGNTOR_API_KEY=your-api-key AGNTOR_SECRET_KEY=your-secret npm start
Hosted MCP

Endpoint: https://mcp.agntor.com/mcp

If authentication is enabled, include:

X-AGNTOR-API-KEY: <your_key>
Integrate with Your Application
import { createAgntorMcpServer } from '@agntor/mcp';
import { TicketIssuer } from '@agntor/sdk';

const issuer = new TicketIssuer({
  signingKey: process.env.AGNTOR_SECRET_KEY!,
  issuer: 'agntor.com',
});

const mcpServer = createAgntorMcpServer(issuer);
// Connect your transport (HTTP, stdio, WebSocket, etc.)

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
