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 workflows.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Searches a meta-index of 500+ MCP servers and A2A tools by capability query, returning compressed, firewall-screened tool metadata via a single 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://workflows.agentdiet.dev/v1/tool-broker)
Output
Returns a compressed (85% token reduction) list of matching MCP servers or A2A tools from a 500+ server index, including tool metadata and Prompt-Guard firewall safety status for the queried capability or endpoint URL.
Example use cases
Agent swarm tool bootstrap
“I'm building a swarm of AI agents and need to know which MCP servers handle SEC filings and GitHub security audits — can you search the meta-router index for those capabilities and give me the compressed tool list?”
Safe proxy verification for untrusted endpoint
“Before my agent connects to this MCP endpoint at https://some-mcp-server.example.com, can you run it through the tool-broker to verify it and check it against the Prompt-Guard firewall?”
Capability discovery for new agent pipeline
“I'm setting up a new autonomous pipeline and need tools for context compression and B2B lead enrichment — search the A2A and MCP index to find what's available so I can wire them into my workflow.”
Technical details
Endpoint
GEThttps://workflows.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 without maintaining its own index, especially when token budget is a concern (85% compression), safety vetting of tool responses is required (Prompt-Guard), or when building swarm architectures that need single-connection access to hundreds of tools.
Side effects
- Empty result set if query matches no indexed tools
- Endpoint URL verification may return unsafe/flagged status if Prompt-Guard detects injection
- Rate limiting or 402 payment required errors if quota exceeded
- Malformed query with minLength < 1 returns validation error
- Index may not reflect newly added MCP servers that haven't been crawled yet
