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/x402-gateway)
Output
Returns a compressed, Prompt-Guard firewall-screened list of matching MCP servers or A2A tools relevant to the capability query, including metadata about each tool, with up to 85% token reduction compared to raw results.
Example use cases
Finding the right tool for SEC filings
“Search the MCP tool index for any servers that can pull SEC filings or EDGAR data — I want to know what's available so my agent can route to the right one.”
Discovering GitHub security audit tools
“Can you query the A2A and MCP meta-router for tools related to GitHub security auditing or code vulnerability scanning? I need to know what's indexed.”
Routing agent to context compression tools
“Look up 'context compression' in the MCP tool discovery index and give me the best matching servers — I want token-efficient options my swarm can use.”
Technical details
Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/x402-gateway?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, especially when you want token-compressed results with built-in prompt-injection protection. It is the right choice when you do not know the exact endpoint URL in advance and need a meta-routing layer across 500+ indexed tools rather than calling a specific known tool directly.
Side effects
- Empty or overly broad query returns too many low-relevance results
- Unrecognized capability keyword yields no matches
- Queried endpoint URL not found in the index
- Firewall (Prompt-Guard) blocks a result flagged as potentially malicious
- Payment (x402) failure if funds insufficient
- Network timeout if upstream MCP servers are slow to respond
