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://email-verify.agentdiet.dev/v1/security-audit-dag)
Output
Returns matching MCP server or A2A tool entries from the index of 500+ tools, including metadata about capabilities, with token-compressed output and prompt-injection filtering applied via the Prompt-Guard firewall.
Example use cases
Discovering tools for SEC filing analysis
“Find me any MCP servers or A2A tools in your index that can pull or parse SEC filings — I need to know what's available before I wire up my research agent.”
Routing agent to GitHub security audit tool
“Search your tool index for something that can run a GitHub security audit — I want to know which MCP endpoint to point my agent at for code vulnerability scanning.”
Validating an endpoint URL before use
“Can you check if this endpoint URL https://some-tool.example.com/api is listed and safe to use in your tool registry? I want to make sure it's not a prompt-injection risk before my agent calls it.”

Endpoint
POSThttps://email-verify.agentdiet.dev/v1/security-audit-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability at runtime, especially when token budget is constrained (85% compression) or when safety from prompt injection is a concern. It is particularly useful as a meta-routing layer before delegating to a specialized downstream tool.
Side effects
- Empty or vague query string returns no matches or low-confidence results
- Queried endpoint URL not found in index returns an empty or null result
- Prompt-Guard firewall may block or sanitize queries that resemble injection attempts
- Payment required (HTTP 402) if x402 micropayment header is missing or insufficient
- Malformed query object returns validation error
