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://shopify-intel.agentdiet.dev/v1/broker/catalog)
Output
A catalog listing of matched MCP servers and A2A tools relevant to the capability query, with token-compressed metadata describing each endpoint's capabilities, supported schemas, and routing information, filtered through a prompt-guard firewall for safety.
Example use cases
Discovering SEC filing tools for agents
“Search the broker catalog for MCP tools that can pull SEC filings — I want to know which endpoints are available and what they support.”
Finding GitHub security audit capabilities
“Look up the MCP tool index for anything related to 'github security' audits so I can route my agent to the right server.”
Routing to a DEX token intelligence tool
“Search the A2A and MCP catalog for 'DEX token intelligence' tools — I need to find an endpoint my trading agent can call.”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/broker/catalog?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover which MCP servers or A2A tools support a given capability at runtime, rather than hardcoding tool URLs. Especially useful for swarm architectures that need to route tasks to the best available external agent or MCP endpoint. Prefer this over manual tool registries when the ecosystem of available tools is large and changes frequently.
Side effects
- Missing or empty 'query' parameter returns a validation error
- Query matches no indexed endpoints — returns empty result set
- Upstream MCP servers may be stale or unavailable, causing incomplete catalog results
- x402 payment failure if USDC balance is insufficient
- Overly broad queries may return too many loosely matched tools
