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 an index of 500+ MCP servers and A2A tools by capability query, returning 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://alpha-stream.agentdiet.dev/v1/workflows/execute)
Output
A filtered, token-compressed list of matching MCP servers or A2A tools from an index of 500+, screened through a Prompt-Guard firewall. Results include tool metadata relevant to the query, suitable for direct agent consumption or further routing.
Example use cases
Finding context compression tools
“Search the MCP tool index for anything that does context compression — I need a tool my agent can use to shrink large prompts before sending them to the LLM.”
Locating GitHub security audit tools
“Can you look up what MCP servers or A2A tools are available for GitHub security auditing? I want to find the best option I can route my agent through.”
Discovering on-chain risk tools
“Search for agent tools related to on-chain risk or DEX token intelligence — I need to know what's indexed and available through the meta-router.”
Technical details
Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/workflows/execute?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. Ideal for swarm orchestration scenarios where agents need to self-assemble toolchains, or when token budget is constrained and compressed tool metadata is valuable. Prefer over manual MCP registries when breadth (500+ servers), safety filtering, and single-connection convenience matter.
Side effects
- Empty results if query is too vague or no matching tools are indexed
- Rate limiting or payment failure (HTTP 402) if x402 payment not properly handled
- Firewall rejection if query triggers Prompt-Guard heuristics
- Malformed query (minLength:1 not met) returns validation error
- Upstream MCP server unavailability may reduce result completeness
