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 polymarket-odds.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-filtered results for agent routing and tool selection

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://polymarket-odds.agentdiet.dev/v1/workflows)
Output
Returns a compressed list of matching MCP servers or A2A tool endpoints relevant to the capability query, including tool names, descriptions, and routing metadata, filtered through a Prompt-Guard firewall with approximately 85% token compression applied.
Example use cases
Discovering a context compression tool
“I need to find an MCP server in the index that handles context compression — can you search for it and tell me what's available?”
Routing GitHub security audits
“Search the tool discovery index for 'github security' — I want to know which A2A agents or MCP endpoints can run a GitHub audit for me.”
Finding B2B lead enrichment agents
“Can you look up 'company enrichment' in the MCP swarm index so I can see which tools I should route my B2B lead enrichment tasks to?”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/workflows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool is best suited for a given capability at runtime, rather than hardcoding tool references. It is especially useful in swarm architectures where task routing decisions must be made across a large, heterogeneous tool ecosystem with token-budget constraints.
Side effects
- Empty query string returns a 400 validation error
- Query matches no tools in the index, returning an empty results set
- Network timeout if the meta-index is unavailable
- Firewall blocks query if it resembles a prompt injection attempt
- Payment required (HTTP 402) if x402 credentials are missing or insufficient
