MCP Configuration¶

The Model Context Protocol (MCP) lets external AI clients — such as Cursor, Claude Desktop, or custom agents — connect to Trust3 and access governance context outside the Trust3 UI. Use MCP when you want inventory, policy, and trust-score answers in the tools your team already uses.

For in-product governance questions, use GIA (Governance Intelligence Agent). MCP is the external, protocol-based path to similar governance data.

Prerequisites¶

Before configuring an MCP client, ensure you have:

Generate an MCP scoped API key¶

MCP clients authenticate with a scoped API key — not the same key you use for the AI Assets Collector. Each key is limited to the permissions you select at creation time.

For MCP configuration, create a key with the MCP (read) scope. That scope allows read-only access to governance context through the MCP server (inventory, policies, trust scores, and similar read operations your role can already see in Trust3).

1. Log in to Trust3 AI.
2. Go to Settings → API Keys.
3. Click Generate scoped key.
4. Set:
   • Name — a label you will recognize later (for example cursor-mcp or claude-desktop).
   • Description (optional) — where the key is used or who owns it (for example Cursor on MacBook).
   • Expiry — select 7 days, 30 days, 90 days, 1 year, or Custom.
   • Scope — select MCP (read).
5. Click Generate, then copy the key immediately. You will not be able to view the full key again.

Use this key as the value for x-trust3ai-key in your MCP configuration below.

MCP client configuration¶

Add the Trust3 MCP server to your client's MCP configuration file (for example mcp.json or the equivalent for your AI tool).

{
  "mcpServers": {
    "trust3ai-mcp-server": {
      "transport": "streamable_http",
      "url": "https://api.na.trust3ai.com/mcp",
      "headers": {
        "Accept": "application/json, text/event-stream",
        "x-trust3ai-key": "<api-key>"
      }
    }
  }
}

Replace <api-key> with the key you generated above.

Verify the connection¶

1. Save your MCP configuration file.
2. Restart your AI client (or reload MCP servers if the client supports hot reload).
3. Confirm the Trust3 MCP server appears in the client's MCP server list.
4. Ask a governance question (for example, "What agents need attention?") and confirm you receive a response grounded in your inventory.
