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 token-intel.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 agent tools by capability query and returns compressed, firewall-filtered 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://token-intel.agentdiet.dev/v1/broker/execute)
Output
Returns a list of matching MCP servers and A2A tool endpoints relevant to the capability query, with token-compressed metadata (up to 85% compression) and Prompt-Guard firewall filtering applied. Response is a generic JSON object containing matched tools, their descriptions, and routing information.
Example use cases
Discovering tools for on-chain risk
“I'm building an agent that needs to assess on-chain risk for crypto wallets — search the MCP index for any tools or servers that cover blockchain risk analysis or DEX token intelligence.”
Finding a GitHub security audit tool
“Can you search the A2A and MCP tool registry for anything that does GitHub security auditing or code vulnerability scanning? I need to wire it into my swarm.”
Routing agent queries through safe proxy
“I want to find and connect to an MCP server for B2B lead enrichment through a safe proxy — can you query the meta-router index with 'company enrichment' and show me what's available?”
Technical details
Endpoint
GEThttps://token-intel.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to use for a given capability, rather than hardcoding a specific tool. Especially useful for swarm architectures where the right tool is unknown at design time, or when token budget is constrained and compressed metadata is valuable. Prefer over manual tool registries when coverage of 500+ servers is needed.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure capability queries
- Firewall blocks potentially malicious or prompt-injection queries
- Upstream MCP server unavailability causes incomplete results
- Payment failure via x402 prevents execution
- Overly broad queries return too many low-relevance results
