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 mcp-security.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 and returns matching endpoints with token-compressed metadata via a Prompt-Guard firewall proxy.

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://mcp-security.agentdiet.dev/v1/broker/catalog)
Output
A catalog response listing matching MCP servers and A2A tools for the queried capability, with 85% token-compressed metadata, safety-filtered through the Prompt-Guard firewall, including tool names, descriptions, and endpoint references.
Example use cases
Agent workflow tool discovery
“I'm building an autonomous agent and need to find MCP servers that can handle GitHub security auditing — can you search the broker catalog and show me what tools are indexed for that capability?”
Safe proxy routing for swarm agents
“My agent swarm needs a single connection point to route tool calls safely — search the catalog for context compression and prompt firewall capabilities so I know which endpoints to use.”
Verify a specific endpoint in the catalog
“Can you check whether https://some-mcp-server.example.com is listed and verified in the MCP broker catalog, and tell me what capability it's indexed for?”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/broker/catalog?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover available MCP servers or A2A tools at runtime without maintaining its own tool registry, especially when token budget is constrained (85% compression) or when prompt-injection safety is a concern. Prefer it over manual tool lists when operating a multi-agent swarm that needs a single meta-router connection.
Side effects
- Missing or empty query string returns a 400 validation error
- No matching tools found for an obscure query returns an empty results set
- Endpoint URL verification returns not-found if the URL is not indexed
- Payment not completed (HTTP 402) if x402 micropayment is not processed
- Firewall blocks a query flagged as a prompt injection attempt
