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 email-verify.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Searches an index of 500+ MCP servers and A2A tools by capability query, routing requests through a token-compressed safe proxy with prompt-guard firewall

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/crypto-alpha-dag)
Output
Returns a structured object listing matching MCP servers or A2A tools relevant to the query, including tool metadata, capability descriptions (compressed by up to 85% for token efficiency), and safety/firewall status from the Prompt-Guard layer.
Example use cases
Discovering tools for SEC filing analysis
“Search the universal MCP tool index for any servers or A2A agents that handle SEC filings or financial intelligence — I want to know what's available before I build my research pipeline.”
Finding context compression MCP servers
“I need to reduce token usage in my agent swarm — can you search the MCP tool discovery index for anything related to context compression or token optimization?”
Validating a specific endpoint URL before use
“Before my agent calls this endpoint, can you run it through the tool discovery router to verify it's indexed and safe to proxy: https://some-mcp-server.example.com/v1/tool”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/crypto-alpha-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability, especially in multi-agent swarm setups where tool selection must be automated. Prefer it over manual tool registries when you need token-compressed tool manifests, prompt injection protection, or single-connection access to 500+ servers without managing individual connections.
Side effects
- Empty or missing query string returns a validation error
- Query matches no indexed tools, returning an empty result set
- Endpoint URL verification fails if the target is unreachable or unindexed
- Prompt-Guard firewall blocks queries containing injection patterns
- Rate limiting or payment failure (x402) blocks the call
