Trust Oracle
Grade any MCP server A–F for trust before wiring it into Claude Code or Cursor.
Overview
Trust Oracle is an MCP server for the Ship phase that returns an independent A–F trust grade for any MCP server and tracks grade drift over time.
What is this MCP server?
- Independent A–F letter grade for arbitrary MCP servers
- Ongoing drift monitoring so trust posture does not silently degrade
- Free remote MCP at wmcp.sh—no purchase or resale of grades
- Streamable HTTP transport for agent-side lookup without local install
- Purpose-built for MCP ecosystem risk, not generic package scoring
- Trust scale: A through F letter grades
- Remote endpoint: https://wmcp.sh/mcp/trust
- Server schema version reference: 2025-12-11

What problem does it solve?
You cannot tell from a README whether an MCP server is safe to connect to your coding agent.
Who is it for?
Builders assembling multiple MCP servers who want a quick external trust signal before connect.
Skip if: Teams that need formal compliance attestations, penetration tests, or source-code review replaced by a single grade.
What do I get? / Deliverables
You get a comparable trust letter grade and drift awareness before adding or keeping an MCP in your stack.
- A–F trust grade for a specified MCP server
- Drift context when the oracle has historical grades

Common Questions / FAQ
Who is Trust Oracle for?
Solo and indie developers using Claude Code, Cursor, or similar agents who install third-party MCP servers and want an independent A–F trust check.
When should I use Trust Oracle?
Use it during Ship/security reviews, when onboarding a new MCP from a registry, or after an MCP version change to see if the grade drifted.
How do I add Trust Oracle to my agent?
Register the streamable HTTP remote at https://wmcp.sh/mcp/trust in your MCP client config per your agent’s MCP remote setup, then call its grading tools from the agent.
