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://agentdiet.dev/v1/broker/catalog)
Output
Returns a catalog of matching MCP servers and A2A tools from the 500+ indexed providers, including capability descriptions, endpoint URLs, and metadata compressed for token efficiency. Results are filtered through the Prompt-Guard firewall for safety.
Example use cases
Discovering context compression tools
“Can you search the AgentDiet tool catalog for any MCP servers that offer context compression? I want to find something that reduces token usage for my agent pipeline.”
Finding GitHub security audit agents
“Search the MCP and A2A catalog for tools that can do GitHub security audits — I need to know which servers are available and what capabilities they expose.”
Verifying a specific endpoint in the catalog
“Check the AgentDiet broker catalog to see if there's a registered MCP tool at https://someprovider.dev/mcp — I want to verify it's indexed and safe to proxy through.”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/broker/catalog?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single connection point to discover, verify, or route across a large corpus of MCP servers and A2A tools without managing individual server connections. Ideal for agents that need to dynamically discover capabilities at runtime rather than hardcoding tool integrations. Prefer this over individual MCP server queries when breadth of discovery matters and token efficiency is important.
Side effects
- Missing or empty query parameter returns validation error
- Query matches no indexed tools and returns empty results
- Upstream MCP server unavailable causing partial catalog response
- Rate limiting or payment failure via x402 protocol
- Overly broad query returns too many low-relevance results
