Describe the solution you'd like

Add a behavioral trust scoring layer that evaluates agent/MCP server trustworthiness before crews execute paid actions or sensitive operations.

When crews interact with external MCP servers or paid APIs, there's no standardized way to verify the other party is trustworthy. The x402 Trust-Provider Interface (open spec) solves this with a beforeSettle hook that queries trust providers before settlement.

The Dominion Observatory already tracks 4,500+ MCP servers with behavioral trust scores via a simple REST API:

curl https://dominion-observatory.sgdata.workers.dev/api/agent-query/{agent-id}

This returns a trust score (0-100), behavioral metrics, and attestation data that can gate crew actions.

Describe alternatives you've considered

A TrustGate tool or middleware in CrewAI that runs before task execution:

from crewai import Agent, Task, Crew
from crewai.tools import TrustGateTool

trust_gate = TrustGateTool(
    provider="dominion-observatory",
    threshold=60,  # PASS if score >= 60
    fail_mode="block"  # block task on FAIL
)

agent = Agent(
    role="Payment Processor",
    tools=[trust_gate],
    # trust_gate auto-checks before executing paid actions
)

Additional context

Observatory dashboard: https://dominion-observatory.sgdata.workers.dev API stats (4,500+ servers): https://dominion-observatory.sgdata.workers.dev/api/stats The x402 HTTP 402 payment protocol is being adopted for agent-to-agent payments, and needs a trust layer.
