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 alpha-stream.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 matches 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://alpha-stream.agentdiet.dev/v1/workflows)
Output
Returns a structured list of matching MCP servers and A2A tools relevant to the capability query, with 85% token-compressed metadata and Prompt-Guard firewall screening applied. Includes tool names, capability descriptions, endpoint URLs, and compliance indicators.
Example use cases
Discovering tools for GitHub security audits
“Search the MCP index for tools that can do GitHub security audits or code vulnerability scanning — I want to see what's available so I can wire the best one into my CI pipeline agent.”
Routing swarm agents to enrichment tools
“I'm building a multi-agent swarm and need to find all MCP servers that support B2B lead enrichment or company data lookup — can you query the tool index and give me the top matches?”
Verifying an unknown MCP endpoint
“I have this MCP endpoint URL I found online — can you run it through the safe-proxy discovery tool to check if it's compliant and safe to connect to before I route any of my agents through it?”
Technical details
Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/workflows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or route to one of many MCP servers or A2A tools without maintaining direct connections to each, especially when token budget is constrained (85% compression), security screening of tool responses is required, or you need a single-connection entry point to a large swarm of heterogeneous agent tools.
Side effects
- Empty or too-short query string returns validation error
- Query matches no indexed tools, returning empty results
- Upstream MCP server index temporarily unavailable, causing timeout
- Prompt-Guard firewall blocks query flagged as adversarial input
- x402 payment failure prevents request from being processed
