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://cve-intel.agentdiet.dev/v1/tool-search)
Output
Returns a list of matching MCP servers and A2A tools from the meta-index, with token-compressed descriptions (up to 85% compression), endpoint URLs, capability summaries, and safety-filtered results via the Prompt-Guard firewall.
Example use cases
Discover SEC filing tools for agent
“Search the tool index for any MCP servers or A2A agents that can pull SEC filings or EDGAR data — I want to route my finance agent through whichever one looks most capable.”
Find email verification agent tools
“I need to find MCP tools that handle email verification — search the meta-index for 'email verification' and show me what's available with their endpoints.”
Route swarm to domain OSINT capability
“My agent swarm needs a domain OSINT capability — search for tools that do domain intelligence or WHOIS lookups across the 500+ indexed MCP servers.”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/tool-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding a specific endpoint. Especially useful in swarm architectures where routing decisions are made at runtime, or when you want token-efficient tool descriptions with built-in prompt injection protection.
Side effects
- Empty query returns validation error
- No matching tools found returns empty results set
- Query too broad may return low-relevance results
- Payment required (HTTP 402) if x402 micropayment not attached
- Upstream MCP server indexing lag may return stale tool listings
