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://x402broker.com/v1/mesh/dispatch)
Output
Returns a structured response identifying matching MCP servers or A2A tools for the query, with token-compressed results and prompt-firewall-filtered output. The response includes routed dispatch results from the indexed pool of 500+ tools.
Example use cases
Discovering tools for a swarm agent
“I'm building a multi-agent swarm and need to find all available MCP servers that can handle GitHub security audits — can you search the tool index and tell me what's out there?”
Finding a context compression tool
“Search the MCP ecosystem for any tools that specialize in context compression or token reduction — I want to plug one into my agent pipeline to cut costs.”
Routing a query through the prompt firewall
“I need to dispatch a capability query for 'domain OSINT and email verification' through the safe-proxy router — find me the best matching A2A tool and route it securely.”
Technical details
Endpoint
POSThttps://x402broker.com/v1/mesh/dispatch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single connection point to discover and route across a large ecosystem of MCP servers and A2A tools, rather than knowing in advance which specific tool to call. Ideal for dynamic agent workflows where the right tool must be discovered at runtime, or when you want prompt-firewall protection and token compression baked into the routing layer.
Side effects
- Empty or too-vague query returns no matching tools
- Query matches no indexed MCP servers — returns empty result set
- Payment not fulfilled (HTTP 402) blocks the request
- Prompt-Guard firewall blocks a query flagged as unsafe
- Idempotency key reuse returns cached prior result
- Malformed query string causes validation error
