How this service works
Single-connection meta-router indexing 500+ MCP servers & A2A tools with 85% token compression and Prompt-Guard firewall. (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-compiler.agentdiet.dev/v1/tool-search)
Output
A list of matching MCP servers and A2A tool endpoints ranked by relevance to the query, with compressed metadata descriptions (85% token reduction) and Prompt-Guard firewall filtering applied. Each result includes tool name, capability summary, and endpoint routing information.
Example use cases
Discovering tools for on-chain risk
“Search the MCP tool index for anything related to on-chain risk or blockchain security analysis — I need to find what agent tools are available for that.”
Finding email verification MCP servers
“Can you look up which MCP servers or A2A tools in the index support email verification or domain OSINT? I want to plug one into my workflow.”
Locating GitHub audit tools for a swarm
“I'm building an agent swarm and need a tool that does GitHub code security auditing — search the MCP tool index and tell me what's available.”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/tool-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool can fulfill a capability at runtime, especially when the agent doesn't have a pre-configured tool list. It is particularly useful for multi-agent swarms needing single-connection access to a broad tool index with built-in token compression and prompt injection protection.
Side effects
- Empty or vague query returns no meaningful matches
- Query too domain-specific may return zero results if no indexed tool covers it
- Rate limiting or 402 payment required if quota exceeded
- Tool index may be stale for recently added or removed MCP servers
- Response schema is generic object — structured fields not guaranteed
