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/a2a-mesh)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with token-compressed metadata and Prompt-Guard firewall filtering applied. May include endpoint URLs, capability descriptions, and safety signals for each matched tool.
Example use cases
Routing agent to right capability
“I need to find an MCP server that can do real-time GitHub security audits — search the tool mesh and tell me which endpoints are available.”
Discovering compression-aware tools
“Search the A2A mesh for tools that support context compression so my agent swarm doesn't burn through tokens — what options are indexed?”
Verifying a tool endpoint before use
“Can you check if this MCP endpoint URL is valid and safe to call before I connect my agent to it: https://some-tool.example.com/v1/mcp?”
Technical details
Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/a2a-mesh?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single connection to discover, evaluate, or route across a large indexed corpus of MCP servers and A2A tools — especially when token efficiency matters or when you need firewall-protected proxying. Prefer alternatives when you need to call a specific known tool directly rather than discovering or routing to one.
Side effects
- Empty or vague query returns low-relevance or no results
- Endpoint URL verification may fail if the target is offline or unreachable
- Token compression may lose nuance in tool descriptions for edge-case queries
- Prompt-Guard firewall may block queries containing injection-like patterns
- Payment required (HTTP 402) if x402 credentials are not provided or are invalid
