Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router
Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router is a paid API for AI agents from shopify-spy.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-23).
Searches a meta-index of 500+ MCP servers and A2A tools by capability query, returning matched endpoints with token-compressed results through a prompt-injection firewall.

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/execute)
Output
Returns a list of matched MCP servers or A2A tool endpoints relevant to the capability query, with metadata and compressed descriptions, filtered through the Prompt-Guard firewall to remove injection risks.
Example use cases
Finding a lead enrichment tool for an agent
“Search the tool index for any MCP servers or A2A endpoints that do B2B lead enrichment or company data lookup — my agent needs to find the right one to use automatically.”
Routing to a code audit capability
“Can you search the agent tool directory for anything related to GitHub security audits or code scanning? I want to find which MCP server my swarm should call for that.”
Discovering token compression endpoints
“Look up what's available for context compression or token budget reduction in the MCP index — I want to find an endpoint my agent can use to shrink large payloads before processing.”
Technical details
Endpoint
POSThttps://shopify-spy.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool is best suited for a given task at runtime, especially when the agent does not have a hard-coded tool list. Prefer this over manually curated tool lists when working across 500+ tools or when you need the built-in prompt-injection firewall to sanitize discovered endpoints before use.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or misspelled capability queries
- Firewall may flag or block results containing suspicious prompt patterns
- Timeout if the meta-index is slow to respond for broad queries
- Malformed endpoint URL input when using URL-verification mode returns an error
