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 defi-yield.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, returning compressed, prompt-safe tool references 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://defi-yield.agentdiet.dev/v1/workflows)
Output
A compressed, Prompt-Guard-filtered list of matching MCP servers and A2A tools from the 500+ tool index, including tool metadata, capability descriptions, and endpoint references relevant to the search query or verified URL — delivered with 85% token compression for agent efficiency.
Example use cases
Finding a context compression tool
“Search the tool index for any MCP servers that support context compression or token reduction — I want to reduce the size of prompts going to my LLM pipeline.”
Locating a GitHub security audit agent
“Can you look up which A2A or MCP tools in the index handle GitHub repository security audits or code scanning?”
Discovering on-chain DeFi risk tools
“Search the meta-router index for any tools that cover on-chain risk analysis or DEX token intelligence — I'm building an agent that needs to assess DeFi yield risks.”
Technical details
Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/workflows?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 tool connections. It is especially valuable when building swarm agents that need to route tasks to the right specialized tool at runtime, when you want a single connection point to 500+ tools with token-compressed responses, or when you need to verify whether a remote MCP/A2A endpoint is live and compliant.
Side effects
- Empty or too-broad query returns too many unfiltered results
- Query for an obscure capability returns no matches if not indexed
- Endpoint URL verification fails if the target URL is unreachable or non-compliant
- Rate limiting or payment failure (HTTP 402) if x402 micropayment is not satisfied
- Malformed query (minLength < 1) returns validation error
