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://x402-audit.agentdiet.dev/v1/workflows/execute)
Output
Returns a list of matching MCP servers and A2A tools relevant to the query, with compressed tool descriptions (up to 85% token reduction), endpoint routing information, and prompt-guard-filtered results to block malicious payloads.
Example use cases
Find MCP tools for GitHub auditing
“Search the MCP tool index for anything that can do GitHub security audits or code analysis — I need to discover available servers and get their endpoints.”
Route swarm through single proxy connection
“I need a single connection point that can route my agent swarm to whatever MCP servers handle on-chain risk and DEX token intelligence — can you find and proxy those tools for me?”
Discover email verification agents
“Look up what A2A or MCP tools are available for email verification and domain OSINT — I want to see what's indexed and which ones have the best capability match.”
Technical details
Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/workflows/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or route to MCP/A2A tools from a large indexed registry without maintaining individual connections to hundreds of servers. Especially useful when token budget is a concern (85% compression), when you need prompt injection protection via the built-in firewall, or when you want a single meta-router instead of managing a swarm of direct integrations.
Side effects
- No matching tools found for the given query — returns empty result set
- Query string is empty or too vague — returns validation error
- Downstream MCP server is unreachable — routing failure with partial results
- Prompt injection detected by firewall — request blocked with security warning
- Payment not processed (x402) — returns 402 Payment Required before serving results
