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/x402-gateway)
Output
Returns a structured list of matched MCP servers and A2A tools relevant to the capability query, including compressed tool descriptions, routing metadata, and endpoint identifiers — delivered with 85% token compression through a prompt-guard firewall.
Example use cases
Discovering SEC filing tools for agent
“Find me any MCP servers or A2A tools in the agentdiet index that handle SEC filings or EDGAR financial data — I need to wire one into my research agent.”
Locating prompt safety firewall tools
“Search the meta-router for tools related to 'prompt guard' or 'prompt firewall' so my agent swarm can route through a safety layer before responding to users.”
Finding DEX token intelligence endpoints
“I'm building a DeFi agent — can you search the agentdiet tool index for any MCP capabilities around DEX token intelligence or on-chain risk analysis?”

Endpoint
GEThttps://email-verify.agentdiet.dev/v1/x402-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools exist for a given capability without hard-coding tool registries. It is ideal for building swarm routers, capability-aware orchestrators, or any system that needs to find the right sub-agent tool at runtime across a large index of 500+ servers, especially when token budget is a concern due to its 85% compression.
Side effects
- Empty or vague query returns no meaningful matches
- Query string missing or too short triggers a validation error
- No matching tools found for a niche capability returns empty result set
- Payment not completed (x402) results in 402 Payment Required response
- Service unavailable if meta-index is being updated
