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 llms-generator.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 relevant endpoints with token-compressed results and prompt-guard filtering.

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://llms-generator.agentdiet.dev/v1/tool-search)
Output
A list of matching MCP servers and A2A tools ranked by relevance to the query, with token-compressed metadata describing each tool's capabilities, endpoint URLs, and routing information. Results pass through the Prompt-Guard firewall before being returned.
Example use cases
Discover context compression tools
“Can you search the MCP tool registry for anything that does context compression or token reduction? I need to slim down my agent's prompt window before sending to a model.”
Find GitHub security audit agent
“Look up what MCP servers or A2A tools are available for GitHub security auditing — I want something my swarm can call to scan repos for vulnerabilities.”
Route to company enrichment capability
“Search for MCP or A2A endpoints that do B2B company enrichment or lead data lookups — I need to wire one into my prospecting agent.”
Technical details
Endpoint
GEThttps://llms-generator.agentdiet.dev/v1/tool-search?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability at runtime, rather than hardcoding tool lists. Especially useful when building swarm architectures that need to self-assemble tool chains or when you need token-efficient tool discovery across a large ecosystem of 500+ servers.
Side effects
- Empty query string returns a 400 or validation error
- No matching tools found returns an empty result set
- Prompt-Guard firewall may block queries that resemble injection attempts
- Downstream MCP index unavailability causes degraded or partial results
- Rate limiting or payment failure (x402) may block the request
