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/mesh)
Output
Returns a structured object listing matching MCP servers or A2A tools relevant to the query, with token-compressed summaries and prompt-injection screening applied. May include endpoint URLs, capability descriptions, and routing metadata.
Example use cases
Discover tools for SEC filing retrieval
“Find me an MCP server or A2A tool in the mesh that can pull SEC filings — I need something reliable for financial data lookups.”
Route capability query for lead enrichment
“Search the MCP tool index for any servers that do B2B lead enrichment or company data lookups — I want to see what's available and get the compressed results back.”
Validate a specific MCP endpoint before calling it
“Can you check if this endpoint URL is listed and verified in the MCP mesh? I want to make sure it's safe to call before routing my agent to it.”
Technical details
Endpoint
POSThttps://shopify-spy.agentdiet.dev/v1/mesh?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover the right MCP server or A2A tool for a capability at runtime, especially when the tool landscape is large or unknown. Prefer it over hardcoded tool lists when you need firewall-screened, token-compressed responses aggregated from 500+ sources in a single call.
Side effects
- Query too vague to match any indexed server — returns empty or low-confidence results
- Prompt-Guard firewall blocks query flagged as injection attempt
- Endpoint URL provided for verification is not found in the index
- Service temporarily unavailable due to mesh connectivity issues
- Payment not fulfilled (x402) — request rejected before processing
