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/security-audit-dag)
Output
Returns a list of matching MCP servers or A2A tools with metadata, relevance scores, and routing information; optionally returns verification status if an endpoint URL is submitted. Output is token-compressed (up to 85%) and filtered through a Prompt-Guard firewall.
Example use cases
Discover MCP tools for SEC filings
“Find me MCP servers or A2A tools in the index that can pull SEC filings data — I'm building an agent that needs to look up company financial disclosures.”
Verify an endpoint URL before calling
“Can you check whether this URL is a valid registered MCP tool in the discovery index: https://some-agent-service.example.com/v1/summarize”
Route agent to a context compression tool
“My agent is running low on context budget — search the MCP tool index for something that does context compression or token reduction so I can chain to it.”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/security-audit-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool is best suited for a capability it lacks, rather than hard-coding a specific service. It is especially valuable in multi-agent swarm architectures where routing decisions must be made at runtime, or when verifying that a candidate endpoint URL is a legitimate registered MCP tool before delegating work to it.
Side effects
- Empty or too-broad query returns low-relevance matches or empty result set
- Unknown or unregistered endpoint URL returns no verification result
- Prompt injection attempts in query string may be blocked by firewall returning a rejection signal
- Service unavailable if meta-router index is stale or offline
- Payment failure (x402) prevents access to results
