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 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 context via a prompt-injection 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://agentdiet.dev/v1/workflows/rag-context-sanitizer)
Output
Returns a structured object listing matching MCP servers or A2A tools relevant to the capability query, including endpoint metadata, token-compressed context about each tool, and prompt-firewall-filtered results to guard against injection attacks.
Example use cases
Discovering tools for SEC filings
“I need to find MCP servers or A2A tools that can pull SEC filings for a given company — search the tool index for 'sec filings' and tell me what's available.”
Routing agent to context compression tool
“My agent pipeline is running out of context window — search the tool directory for 'context compression' and find me an MCP endpoint I can plug in.”
Verifying an MCP endpoint URL
“Can you check whether this URL is a valid, compliant MCP endpoint? Verify https://example.com/mcp-server against the tool registry and tell me what it supports.”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/workflows/rag-context-sanitizer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hard-coding tool URLs. It is especially useful when building swarm-style multi-agent systems that need safe, compressed, firewall-protected routing across a large tool ecosystem. Prefer it over manual tool registries when you want prompt-injection protection and token efficiency built in.
Side effects
- Empty or too-vague query returns no matching tools
- Endpoint URL verification fails if the target is offline or non-compliant
- Token compression artifacts may reduce result fidelity for niche queries
- Index may not reflect newly registered MCP servers in real time
- Payment failure (x402) blocks access before query is processed
