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/web-rag-shield-dag)
Output
Returns a list of capability-matched MCP servers or A2A tools from a 500+ item index, with relevance scores, compressed metadata (85% token reduction), and a Prompt-Guard safety assessment for each matched endpoint.
Example use cases
Discover SEC filing tools for agent
“Find me an MCP server in the index that can pull SEC filings — I need the best-matched endpoint so my agent can route there automatically.”
Validate suspicious endpoint URL safety
“Can you check whether this endpoint URL is safe to call from my agent swarm? I want to make sure it passes the prompt-guard firewall before I route traffic to it.”
Route to context compression capability
“Search the 500+ tool index for something that does context compression — my agent needs to reduce token usage and I want the best available MCP server for that.”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/web-rag-shield-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which of 500+ MCP servers or A2A tools best matches a capability need, or when validating that a third-party endpoint is safe to proxy through before calling it. Prefer this over hardcoded tool registries when the agent operates in a swarm context and needs real-time routing with token-efficient responses and built-in prompt-injection protection.
Side effects
- Empty or vague query returns low-confidence or zero matches
- Endpoint URL provided for verification may not be indexed, returning no safety data
- Rate limiting or x402 payment failure causes 402 response requiring micropayment
- Query too broad may return too many low-relevance results
- Prompt-guard firewall may flag adversarial query strings and refuse to process them
