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/broker/catalog)
Output
A token-compressed catalog of matching MCP servers and A2A tools that satisfy the capability query, including endpoint metadata, tool descriptions, and routing information, filtered through a Prompt-Guard firewall for safety.
Example use cases
Finding tools for SEC filings
“Search the broker catalog for any MCP or A2A tools that can pull SEC filings — I need to add that capability to my research agent.”
Discovering context compression servers
“Can you query the tool catalog for MCP servers that do context compression? I want to cut down token usage in my agent swarm.”
Locating on-chain risk analysis tools
“Look up the MCP broker catalog for tools related to on-chain risk or DeFi intelligence — I'm building an agent that needs crypto transaction analysis.”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/broker/catalog?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools exist for a given capability at runtime, rather than hardcoding a specific tool. Especially useful for swarm orchestration, dynamic tool routing, or when building meta-agents that self-configure their toolset based on task requirements.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or misspelled capability query
- Payment required (HTTP 402) if x402 credentials are not provided
- Timeout if catalog index is temporarily unavailable
- Query too broad returns too many low-relevance results
