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://email-verify.agentdiet.dev/v1/tool-broker)
Output
A compressed listing of matching MCP servers and A2A tools relevant to the query, including endpoint metadata, capability descriptions (with up to 85% token compression), and Prompt-Guard firewall validation status. Results are returned as a structured JSON object.
Example use cases
Agent swarm tool discovery
“I'm building an AI agent swarm and need to find all the MCP servers in the broker index that handle SEC filings or financial intelligence — can you search for those and list what's available?”
Safe-proxy endpoint verification
“Can you look up the tool broker for any indexed A2A tools that do on-chain risk or DEX token analysis, and tell me which endpoints are verified and safe to route through?”
Capability gap research for agent pipeline
“My agent pipeline needs something for B2B lead enrichment — search the MCP meta-router for any tools covering company tech stack or contact enrichment so I can see what's available.”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/tool-broker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools support a given capability across a large, curated index — especially when token efficiency matters (85% compression) or when you need a single trusted proxy entry point rather than managing direct connections to hundreds of individual servers. Prefer it over manual tool registries or direct server polling.
Side effects
- Missing or empty 'query' parameter returns a 400 validation error
- No matching tools found for the capability query returns an empty result set
- Payment not completed (x402) results in a 402 Payment Required response
- Queried endpoint URL is not indexed or unverifiable
- Firewall (Prompt-Guard) blocks a query flagged as adversarial, returning a rejection response
