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://agentdiet.dev/v1/workflows/execute)
Output
Returns a list of matching MCP servers and A2A agent tools from the 500+ tool index, including capability metadata, endpoint routing information, and relevance scores. Responses are compressed using 85% token reduction and filtered through a Prompt-Guard firewall to block injection attempts.
Example use cases
Finding tools for GitHub security audits
“Search the MCP tool index for any agents or servers that can run GitHub security audits or code scanning — I want to see what's available without having to connect to each one individually.”
Discovering on-chain risk analysis tools
“Look up what MCP servers or A2A tools support on-chain risk analysis or smart contract auditing — give me the best matching ones from the index.”
Routing to a context compression capability
“Find me an MCP server or agent tool that supports context compression or token reduction — I'm trying to reduce prompt size across my swarm and want to see what's indexed.”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/workflows/execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or orchestration system needs to discover the right MCP server or A2A tool for a specific capability without maintaining direct connections to hundreds of individual servers. Ideal for swarm architectures where dynamic tool routing is needed, or when you want a single-connection proxy with built-in token compression and prompt injection protection.
Side effects
- No matching tools found for the given query — returns empty result set
- Query string too vague or unsupported — may return low-relevance matches
- Endpoint URL verification fails if the target is offline or non-compliant
- Rate limiting or payment gateway rejection if x402 payment fails
- Index may lag behind newly registered MCP servers
