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://email-verify.agentdiet.dev/v1/broker/catalog)
Output
Returns a catalog listing of matching MCP servers and A2A tools from the 500+ indexed services, with token-compressed metadata (up to 85% compression) about each tool's capabilities, endpoints, and connection details, filtered through a Prompt-Guard firewall for safety.
Example use cases
Finding tools for financial data
“Search the broker catalog for MCP servers or A2A tools that can handle SEC filings and financial document retrieval — I want to see what's available so I can wire one into my research agent.”
Discovering GitHub security audit tools
“Can you query the tool discovery catalog for anything related to GitHub security audits or code scanning? I'm building an agent pipeline and need to find the right MCP server to connect.”
Locating context compression capabilities
“Search the MCP catalog for tools that do context compression or token reduction — I want to see which servers are indexed that can help reduce token usage in my swarm agent setup.”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/broker/catalog?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability without hardcoding connections. Prefer this over manual tool registries when you need a single-connection meta-router across 500+ services, want built-in Prompt-Guard firewall protection, or need token-compressed responses to minimize LLM context usage in agentic pipelines.
Side effects
- Empty query string returns validation error (minLength:1 required)
- Query matches no indexed tools returns empty result set
- Downstream MCP server unavailable returns partial or degraded catalog
- Payment not fulfilled returns HTTP 402 requiring x402 micropayment
- Rate limiting or quota exceeded returns 429 error
- Malformed query or unsupported characters may return 400 error
