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/security-audit-dag)
Output
Returns a token-compressed listing of matching MCP servers and A2A tools relevant to the query, including capability descriptions, endpoint URLs, and prompt-guard safety status. The 85% token compression means results are dense and agent-ready.
Example use cases
Swarm capability routing for SEC data
“I'm building an agent swarm and need to find which MCP servers in your index can handle SEC filings or financial document retrieval — search for 'SEC filings' and tell me what's available.”
Safe endpoint URL verification
“Before my agent calls this endpoint URL https://some-random-mcp.dev/api/tool, can you run it through your prompt-guard firewall to check if it's safe to use?”
Discovering context compression tools
“My agent pipeline is running out of tokens — search your MCP index for tools that do context compression or token reduction so I can plug one in.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/security-audit-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability at runtime, especially in multi-agent swarms where routing decisions must be made programmatically. It is also the right choice when you want to verify an unknown endpoint URL before calling it, benefiting from the built-in prompt-injection firewall.
Side effects
- Empty or too-vague query returns no useful matches
- Queried endpoint URL flagged as potentially unsafe by Prompt-Guard firewall
- Service unavailable if x402 payment fails or USDC balance insufficient
- Query returns stale index data if MCP server list has not been refreshed recently
- Malformed query string causes validation error
