Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router
Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router is a paid API for AI agents from shopify-spy.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown.
Searches an index of 500+ MCP servers and A2A tools by capability query, returning compressed, firewall-screened results via a single meta-router connection

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://shopify-spy.agentdiet.dev/v1/a2a-mesh)
Output
A compressed index of matching MCP servers and A2A tools ranked by relevance to the query, including capability descriptions, endpoint URLs, and metadata — filtered through a Prompt-Guard firewall to remove malicious or non-compliant results. Token usage is reduced by approximately 85% versus raw tool manifests.
Example use cases
Discovering SEC filing retrieval tools
“Find me an MCP server in the agent mesh that can pull SEC filings — I need to know which tools are available and what capabilities they expose.”
Locating email verification agents
“Search the MCP tool index for any agents that handle email verification so I can wire one into my lead enrichment pipeline.”
Finding on-chain risk analysis tools
“Look through the A2A mesh and tell me which tools support on-chain risk or DEX token intelligence — I need something I can route crypto-related queries to.”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/a2a-mesh?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which MCP servers or A2A tools exist for a given capability without knowing specific endpoint URLs in advance. It is especially useful when building multi-agent swarms that need dynamic tool routing, or when you want firewall-screened, token-compressed results rather than raw tool manifests. Prefer it over manual tool registries when querying across 500+ tools simultaneously.
Side effects
- Empty query string returns 400 validation error
- No matching tools found for obscure capability queries returns empty result set
- Prompt-Guard firewall blocks queries flagged as adversarial or injection attempts
- Upstream MCP server index may be stale if recently added servers haven't been indexed
- x402 payment failure results in 402 response before query is processed
- Highly ambiguous queries may return low-relevance tool matches
