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/mcp-router)
Output
Returns a list of matching MCP server entries or A2A tool descriptors relevant to the search query, with capability metadata in compressed form, enabling the calling agent to identify and connect to the appropriate downstream tool or endpoint.
Example use cases
Finding a GitHub security audit tool
“Search the MCP router for tools that can run GitHub security audits on a repository — I need the best available agent tool for that capability.”
Routing to on-chain risk analysis
“Find me an MCP server or A2A tool that handles on-chain risk analysis or DEX token intelligence — I want to connect my agent to the right one without manually scanning hundreds of servers.”
Discovering email verification agents
“Search across all indexed MCP tools for something that does email verification or domain OSINT — I want to know what's available and which endpoint to call.”
Technical details
Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/mcp-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to use for a given capability, rather than hardcoding a specific tool. It is especially useful in multi-agent swarms or orchestration pipelines where the right downstream tool must be selected at runtime. Prefer this over manually curated tool lists when you need coverage across 500+ indexed servers with built-in safety filtering.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure query returns empty result set
- Queried endpoint URL fails SLA check and is flagged as non-compliant
- Prompt injection attempt blocked by Prompt-Guard firewall
- Payment not processed via x402 returns HTTP 402 with payment details
