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-spy.agentdiet.dev/v1/broker/catalog)
Output
Returns a compressed catalog of matching MCP servers and A2A tools, including tool names, capability descriptions, endpoint URLs, and routing metadata — filtered through a Prompt-Guard firewall and compressed to reduce token usage by up to 85%.
Example use cases
Finding a GitHub security audit tool
“I need to find an MCP server in the broker catalog that can audit GitHub repositories for security vulnerabilities — search for 'github security' and show me what's available.”
Discovering on-chain risk analysis agents
“Can you search the agentdiet tool catalog for any A2A agents or MCP servers that handle on-chain risk scoring or crypto wallet risk analysis?”
Locating email verification endpoints
“Search the broker catalog for tools that do email verification or validation and list the ones that are available to route through.”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/broker/catalog?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover and route to the right MCP server or A2A tool for a capability it doesn't already have wired in — especially useful for swarm orchestration or when building meta-agents that need to delegate subtasks to specialized tools. Prefer this over hardcoded tool registries when the tool landscape changes frequently or when you need a single connection point to 500+ endpoints with built-in prompt safety filtering.
Side effects
- Empty query string returns validation error
- No matching tools found returns empty catalog result
- Upstream MCP server unavailability may cause partial results
- Malformed query may return unexpected or irrelevant tool matches
- Payment failure via x402 returns 402 status blocking access
