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/api/mcp/audit)
Output
Returns a list of matching MCP servers or A2A tools from a 500+ entry index, with 85% token-compressed metadata, capability summaries, and prompt-guard firewall screening applied to results.
Example use cases
Discover tools for SEC filing analysis
“Can you search the MCP tool index for anything that handles SEC filings or financial document analysis? I want to know what agent tools are available for that.”
Verify a specific endpoint is indexed
“Check if https://some-agent-api.example.com/api/tool is listed in the MCP or A2A tool registry — I want to confirm it's a known, verified endpoint before routing traffic to it.”
Find context compression capabilities
“I need to reduce token usage in my agent pipeline — search the tool index for MCP servers that offer context compression or token reduction capabilities.”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/api/mcp/audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability at runtime, especially when the tool landscape is unknown or when you want to verify a specific endpoint's legitimacy before proxying traffic through it. Prefer it over static tool registries when you need live index coverage and built-in prompt-injection protection.
Side effects
- Missing or empty query parameter returns validation error
- Query matches no tools in the index, returning empty result set
- Endpoint URL verification returns not-found if URL is not indexed
- Service unavailable if the meta-router backend is down
- Payment required (HTTP 402) if x402 micropayment not completed
