Overview

AI-generated overview

Agntor Trust is a local MCP server that lets an assistant check AI agent identity and trust scores, guard prompts and tool calls, redact sensitive output, and,

What you can do
Look up agent identity and trust: retrieve agent cards and registrations, check certification, health metrics and trust scores, and register or verify agents. Screen inputs and outputs: scan prompts for injection, redact PII and secrets, and allow or block tool execution. Handle escrow and audit: create agent-to-agent escrow tasks and issue signed JWT tickets for x402 transactions. Administer agents: search agents by trust score, tier or capability, and trigger an emergency kill switch.
When to use it
Useful when an assistant works with third-party or other AI agents and needs to verify who they are, how trustworthy they are, or whether they are certified before interacting. Also suited to workflows that want prompt-injection screening, output redaction, tool-call policies, or agent-to-agent escrow and x402 payment tickets.
Requirements
Runs locally as an npm package (npx @agntor/mcp) over stdio, or as an HTTP server on port 3100 by default. Needs Node.js and network access to the Agntor backend at app.agntor.com. The AGNTOR_API_KEY environment variable is required for API-backed tools; AGNTOR_SECRET_KEY is used to sign audit tickets. A hosted endpoint is also offered with an X-AGNTOR-API-KEY header.
Before you install
Requires two secrets: AGNTOR_API_KEY for backend calls and AGNTOR_SECRET_KEY, a JWT signing key for audit tickets; keep both out of logs and shared configs. Several tools change state on the Agntor network, including registering agents, creating escrow tasks for agent-to-agent payment, and activating a kill switch that disables an agent. Agent data and prompts are sent to the Agntor backend.

Installation

In SourceWeft

  1. Open Trust in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

@agntor/mcp

MCP (Model Context Protocol) server for AI agent trust, discovery, and certification. Connects Claude, Cursor, VSCode, and any MCP-compatible client to the Agntor trust network.

Installation

bash
npm install -g @agntor/mcp

Add to MCP Clients

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%/Claude/claude_desktop_config.json (Windows):

json
{  "mcpServers": {    "agntor": {      "command": "npx",      "args": ["-y", "@agntor/mcp"]    }  }}

Cursor

  1. Open Cursor Settings
  2. Go to Features > Model Context Protocol
  3. Add new server:
    • Name: Agntor Trust
    • Command: npx
    • Args: -y @agntor/mcp

Cline (VSCode Extension)

Edit ~/.cline/mcp.json:

json
{  "mcpServers": {    "agntor": {      "command": "npx",      "args": ["-y", "@agntor/mcp"]    }  }}

Continue (VSCode Extension)

Edit ~/.continue/config.json:

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

Quick Start

Run Standalone Server

bash
# 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

typescript
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.)

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
