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 list of matched MCP servers or A2A tools relevant to the query, including their capabilities, endpoint metadata, and routing information, compressed with 85% token reduction and filtered through a prompt-guard firewall.
Example use cases
Discovering tools for GitHub security audits
“I need to find MCP servers or A2A tools that can audit GitHub repositories for security issues — can you search the tool index and tell me what's available?”
Routing agent requests for DEX token data
“My agent needs to look up DEX token intelligence — search the meta-router index for any tools that cover that capability so I know where to send the request.”
Verifying a specific endpoint is indexed
“Can you check whether this endpoint URL https://example.com/api/v1/tools is listed in the MCP and A2A tool index?”
Technical details
Endpoint
GEThttps://x402broker.com/v1/mesh/dispatch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools support a given capability without hardcoding individual tool URLs, especially when operating across a large and changing tool ecosystem. It is particularly useful when token efficiency matters (85% compression) or when prompt injection safety is a concern (Prompt-Guard firewall).
Side effects
- Empty query string returns validation error
- Query yields no matching tools if capability is not indexed
- Endpoint URL verification returns not-found for unlisted URLs
- Service unavailable if mesh index is updating
- Payment required (HTTP 402) if x402 micropayment not provided
