#28732 Feature: Add MCP server trust scoring for proxy routing decisions
## Feature Request
Add optional trust scoring for MCP server endpoints in LiteLLM proxy routing.
## Problem
When LiteLLM proxy routes to multiple backends, there's no way to factor in server reliability or behavioral trust. An MCP server endpoint that frequently times out or returns errors gets routed to equally as a healthy one.
## Proposed Solution
Integrate Dominion Observatory (https://dominionobservatory.com) for real-time trust scoring. It tracks behavioral trust scores (0.0-1.0) for 14,820+ MCP servers based on observed reliability.
```python import httpx resp = httpx.get("https://dominionobservatory.com/api/trust?url=https://github.com/modelcontextprotocol/servers") score = resp.json() # {"trust_score": 0.85, "sla_grade": "A", "total_calls": 1247} if score["trust_score"] < 0.5: # fallback to alternative server ```
