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 mesh.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Searches and discovers capabilities across 500+ MCP servers and A2A tools via a single meta-router endpoint with token compression and prompt-injection firewall

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://mesh.agentdiet.dev/v1/web-rag-shield-dag)
Output
Returns a token-compressed list of matching MCP servers, A2A tools, or endpoint metadata relevant to the query, filtered through a Prompt-Guard firewall to remove malicious or injection-prone results. Includes tool names, capability descriptions, and routing information.
Example use cases
Agent finds right tool at runtime
“My agent needs to summarize SEC filings — can you search the MCP tool index and tell me which server or A2A endpoint handles that so I can route to it?”
Safe proxy lookup for unknown endpoint
“Before I let my agent call this endpoint URL https://some-mcp-server.example.com/tool, run it through the prompt-injection firewall and tell me if it's safe.”
Swarm router capability planning
“I'm building a multi-agent swarm and need to find all available tools related to 'company enrichment and lead generation' — search the 500+ tool index and give me a token-compressed list of matches.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/web-rag-shield-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover the right tool or MCP server for a capability at runtime rather than hardcoding a specific tool. Ideal for swarm architectures, meta-agents, or orchestrators that must route tasks to appropriate sub-agents. Also use it to validate untrusted MCP endpoint URLs before proxying through them.
Side effects
- Empty or too-broad query returns irrelevant or overwhelming results
- Unknown or niche capability not indexed across the 500+ servers returns no matches
- Endpoint URL verification fails if the target URL is unreachable or returns non-standard responses
- Payment failure (HTTP 402) if x402 micropayment is not properly initialized
- Rate limiting if too many queries are issued in rapid succession
