Feature: Add trust verification for MCP servers before orchestration

[vdineshk]

Feature Request

Add optional pre-call trust verification for MCP servers in mcp-agent orchestration workflows.

Problem

When mcp-agent orchestrates across multiple MCP servers, there's no built-in way to verify server reliability. An unreliable server in a multi-step workflow can cause cascade failures.

Proposed Solution

Integrate Dominion Observatory (https://dominionobservatory.com) as an optional trust gate. It tracks behavioral trust scores for 14,820+ MCP servers based on real observed reliability.

import httpx
resp = httpx.get("https://dominionobservatory.com/api/trust?url=https://github.com/modelcontextprotocol/servers")
print(resp.json())  # {trust_score: 0.85, sla_grade: "A", total_calls: 1247}
