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
A paginated list of matching MCP servers and A2A tools relevant to the capability query, including endpoint metadata, descriptions, and URLs, with token-compressed output and prompt-injection firewall applied. Includes a cursor for fetching subsequent pages.
Example use cases
Discover tools for SEC filings
“Search the MCP tool registry for any servers that can pull or parse SEC filings — show me up to 20 results.”
Find context compression endpoints
“I need an agent tool that does context or token compression — search the tool index for 'context compression' and return the best matches.”
Route swarm to email verification tools
“Look through the MCP tool index for email verification services my agent swarm can use — query for 'email verification' and give me the top 15.”

Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/mesh?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or orchestrator needs to dynamically discover which MCP servers or A2A tools exist for a given capability, rather than hardcoding tool references. It is especially useful in swarm-routing scenarios where the agent must find and delegate to appropriate sub-agents or tools at runtime. Prefer it over manual tool catalogs when you need coverage across 500+ indexed servers in a single query.
Side effects
- Empty results if the query string is too narrow or uses non-indexed terminology
- Pagination errors if an invalid or expired cursor is supplied
- Rate limiting or payment failure if the x402 micropayment is not completed
- Timeout if the meta-router index is temporarily unavailable
- Malformed query (empty string) rejected due to minLength:1 constraint
