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/crypto-alpha-dag)
Output
Returns a list of matching MCP servers and A2A tools from a 500+ endpoint index, including capability descriptions, endpoint URLs, and token-compressed metadata. Results are filtered through a Prompt-Guard firewall before being returned.
Example use cases
Discovering tools for SEC filing research
“Search the MCP tool index for anything related to SEC filings or financial document retrieval — I want to find which A2A tools or MCP servers can handle that.”
Finding a safe proxy for crypto analysis agents
“Look up available MCP servers or A2A tools that cover on-chain risk or DEX token intelligence so I can route my trading bot through the right capability.”
Locating context compression tools for a swarm
“Search for MCP endpoints that offer context compression or token reduction — I'm building a multi-agent swarm and need to minimize token usage across tool calls.”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/crypto-alpha-dag?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover new tools or MCP servers at runtime rather than relying on a hardcoded tool list. Ideal for swarm architectures where capability routing must adapt to task requirements, or when verifying whether a specific endpoint URL is indexed and safe.
Side effects
- Empty or vague query returns no meaningful matches
- Query too broad returns hundreds of low-relevance results
- Endpoint URL verification returns unresolvable or stale records
- Firewall blocks query flagged as prompt injection
- Payment not completed results in HTTP 402 response
