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/x402-broker)
Output
Returns a list of matching MCP servers and A2A tools from a 500+ endpoint index, with metadata about each tool's capabilities, endpoint URLs, and relevance to the query — delivered with up to 85% token compression to minimize context usage, and filtered through a Prompt-Guard firewall to block injected malicious content.
Example use cases
Discover tools for SEC filing research
“Search the MCP tool router for any servers that can pull SEC EDGAR 10-K or 10-Q filings — I need to find which tools are available for public company financial intelligence.”
Find prompt-safe MCP proxy for GitHub audits
“I need to find an MCP server that can do GitHub repo security auditing — search the tool index for 'github security' and show me what's available with safe proxying.”
Route swarm agents to lead enrichment tools
“My agent swarm needs B2B company enrichment capabilities — search the A2A tool discovery router for 'company enrichment' and return the best matching endpoints I can route to.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/x402-broker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover and route to external MCP servers or A2A tools without hard-coding individual tool connections — especially useful for swarm architectures needing a single meta-router, when token budget is constrained (85% compression), or when untrusted tool responses need firewall filtering before ingestion.
Side effects
- Empty query string returns validation error
- No matching tools found for niche or misspelled query
- Firewall may block or sanitize responses containing prompt injection patterns
- x402 payment failure if USDC balance insufficient
- Endpoint URL verification may return unresolvable if target server is offline
