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-router)
Output
Returns a list of matched MCP servers or A2A tools relevant to the query, with compressed tool descriptions (85% token reduction), safety-screened through the Prompt-Guard firewall, along with metadata about each matched endpoint such as capability tags and routing info.
Example use cases
Finding tools for SEC filings
“Search the swarm router for any MCP servers or A2A tools that can pull SEC filings or financial disclosures — I need to know what's available before I build my research agent.”
Discovering GitHub security audit tools
“Can you search for agent tools in the swarm that handle GitHub security audits or code scanning? I want a single connection that routes me to the right MCP server.”
Checking if an endpoint is indexed
“Verify whether this endpoint URL is already indexed in the swarm router: https://hn-pulse.agentdiet.dev/v1/sec-filings — I want to know if it's safe-proxied and discoverable.”
Technical details
Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/swarm-router?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 when token budget is a concern (85% compression) or when prompt injection safety is required via the built-in Prompt-Guard firewall. Prefer this over direct tool connections when building agent orchestration layers that need to dynamically find the right tool for a given capability at runtime.
Side effects
- Empty query string returns a validation error
- No matching tools found for obscure capability queries returns empty result set
- Endpoint URL verification may return unverified or unlisted status if not indexed
- Token compression edge cases may truncate tool descriptions unexpectedly
- Rate limiting or payment failure (HTTP 402) if x402 micropayment is not satisfied
