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/broker/catalog)
Output
A token-compressed (up to 85% reduction) list of matching MCP servers or A2A tools from the 500+ item index, including capability metadata and routing info, filtered through a Prompt-Guard firewall to remove injection risks.
Example use cases
Routing agent to right tool
“I need to find an MCP server that can do GitHub security audits — search the tool catalog for 'github security' and tell me what's available.”
Capability gap discovery for swarm
“Before I build my research swarm, can you query the MCP catalog for 'ArXiv paper search' so I know which tools I can plug in for academic literature retrieval?”
Verifying an endpoint before use
“Can you check whether this endpoint URL is indexed and verified in the AgentDiet broker catalog: https://some-mcp-server.example.com/v1/tool”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/broker/catalog?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to discover which MCP server or A2A tool supports a specific capability before routing a task, especially when operating across a large heterogeneous tool ecosystem. It is preferable over manual tool registries when token efficiency matters and when prompt-injection safety is required for untrusted tool sources.
Side effects
- Empty or too-vague query returns no matches or overly broad results
- Query for an endpoint URL not in the catalog returns no verification result
- Rate limiting or payment failure (x402) blocks access
- Firewall may reject queries resembling prompt-injection patterns
- Catalog staleness may mean newly added servers are not yet indexed
