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/swarm-execute)
Output
Returns a structured object containing matched tools or MCP servers relevant to the query, along with routing metadata, token-compressed responses from the swarm, and any firewall screening results. The response schema is an open object that varies based on which downstream tools are invoked.
Example use cases
Discover tools for SEC filing analysis
“Search across all indexed MCP servers and A2A tools for anything that handles SEC filings or EDGAR data — I want to find the right tool and send my query through the swarm router.”
Route capability query to best agent
“I need to find an MCP tool that does B2B lead enrichment — can you search the 500+ tool index for the best match and proxy my request through it?”
Find prompt-firewall-protected web tool
“Search for any available tools that do live web search or content grounding, and make sure the request goes through the Prompt-Guard firewall before executing.”
Technical details
Endpoint
POSThttps://x402broker.com/v1/swarm-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which of 500+ MCP servers or A2A tools best matches a capability requirement, or when you want to route a task through a single connection rather than managing multiple integrations. Ideal for agent orchestration workflows where the correct downstream tool is unknown, or when token budget is constrained and 85% compression is valuable. Prefer over direct tool calls when prompt injection protection is required.
Side effects
- Query too vague — returns no matching tools or low-relevance results
- Downstream MCP server unavailable — swarm router may return partial results
- Prompt-Guard firewall blocks query if it resembles an injection attempt
- Payment not processed — x402 micropayment failure blocks execution
- Idempotency-Key collision — retried requests may return cached results
