Question 1

What is a ProxyScore?

Accepted Answer

ProxyScore is a 0–100 score that predicts how likely an AI orchestrator (LangGraph, CrewAI, OpenAI Assistants) selects your MCP server or CLI tool over competitors. It measures Semantic Discovery (35 pts), Schema quality (30 pts), Reliability (25 pts), and Governance (10 pts).

Question 2

What is an MCP server?

Accepted Answer

MCP (Model Context Protocol) is an open standard for integrating tools with AI agents. MCP servers expose tools that AI orchestrators like Claude, LangGraph, and CrewAI can discover and call autonomously. There are over 26,000 discoverable MCP servers.

Question 3

How do I make my agent discoverable by AI orchestrators?

Accepted Answer

To maximize orchestrator selection, your MCP server should have: imperative verb tool names (e.g. 'generate_report' not 'report'), detailed descriptions under 250 characters, complete JSON parameter schemas with required arrays, and output schemas. ProxyRank audits all four layers and suggests specific improvements.

Question 4

Is ProxyRank free?

Accepted Answer

Yes. The basic ProxyRank audit (75 of 100 points) is always free. Full 100-point scoring including live reliability probes is available in Phase 2.
