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://serp-extract.agentdiet.dev/v1/execute)
Output
A structured object listing matching MCP servers and A2A tools relevant to the query, with token-compressed capability descriptions (up to 85% compression), safety-screened through a Prompt-Guard firewall, including endpoint URLs, tool names, and capability summaries.
Example use cases
Finding a tool for GitHub security audits
“Search the MCP tool index for any servers or A2A agents that can do GitHub security audits or code vulnerability scanning — show me what's available.”
Verifying a specific MCP endpoint
“Check whether this MCP endpoint URL is valid and compliant: https://example-agent.dev/mcp — verify it through the safe-proxy and tell me what it does.”
Discovering context compression tools
“I need an agent tool that supports context compression to reduce token usage — search the A2A and MCP registry for anything that matches that capability.”
Technical details
Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools exist for a given capability, rather than hardcoding tool URLs. Prefer it over manual registries when you need token-efficient results, built-in prompt-injection safety screening, or want to verify an unknown endpoint URL before calling it.
Side effects
- Empty query string returns validation error
- No matching tools found for niche or overly specific queries
- Endpoint URL verification fails if target is offline or non-compliant
- Firewall blocks results flagged as prompt-injection risks
- Rate limiting or payment failure (x402) if micropayment is not provided
