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/mesh/dispatch)
Output
Returns matched MCP server or A2A tool metadata, including routing information, with responses compressed by up to 85% for token efficiency and filtered through a Prompt-Guard firewall to block injection attacks.
Example use cases
Swarm agent tool discovery
“I'm building a multi-agent workflow and need to find which MCP server handles GitHub security audits — can you search the tool index and tell me what's available?”
Safe proxy for untrusted tool calls
“I want to call an external A2A tool for B2B lead enrichment but I need it filtered through a prompt firewall first — can you route the request safely through the mesh dispatcher?”
Single-query capability routing
“My agent needs context compression — search across all indexed MCP servers and dispatch me to whichever one best handles token reduction for large documents.”
Technical details
Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/mesh/dispatch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover and route to one of many MCP servers or A2A tools without maintaining individual connections to each — especially useful in swarm/multi-agent architectures where dynamic tool selection is needed, or when you want prompt-injection protection on tool calls and token-compressed responses.
Side effects
- No matching tool found for the given query — returns empty or low-confidence results
- Query is too vague to disambiguate between multiple tool candidates
- Prompt-Guard firewall blocks a request flagged as a potential injection
- Upstream MCP server is unreachable or returns an error
- Payment not accepted or x402 authentication failure
