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://hn-pulse.agentdiet.dev/v1/swarm-execute)
Output
Returns a compressed list of matching MCP servers or A2A tool endpoints that satisfy the capability query, with 85% token compression applied and Prompt-Guard firewall screening. Results include tool metadata, capabilities, and routing details needed to invoke the matched endpoints.
Example use cases
Discover tools for on-chain risk analysis
“I need to find any MCP servers or A2A agents in the swarm that specialize in on-chain risk scoring or smart contract auditing — can you search the meta-router for that capability?”
Find a prompt firewall or content moderation tool
“Search the swarm index for tools that handle prompt injection defense or content moderation — I want to know which MCP endpoints are available for that.”
Route a query to the right enrichment agent
“I'm building an agent pipeline and need to find which A2A tools in the 500+ index can do B2B lead enrichment or domain OSINT — can you query the swarm router with 'company enrichment' and tell me what comes back?”
Technical details
Endpoint
POSThttps://hn-pulse.agentdiet.dev/v1/swarm-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding a specific tool. It is especially useful in multi-agent orchestration pipelines where the right downstream tool is not known in advance, or when building a swarm router that needs a single-connection entry point to hundreds of specialized agents with built-in token compression and safety filtering.
Side effects
- Empty results when no indexed tool matches the query — try broader or alternate keywords
- Query too short or vague — minLength of 1 enforced but very short queries may return low-relevance results
- Rate limiting or 402 payment required if USDC micropayment not satisfied
- Firewall rejection if query pattern triggers Prompt-Guard heuristics
- Timeout if backend swarm index is temporarily unavailable
