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, including endpoint metadata, capability descriptions, and compressed tool response data, all passed through a Prompt-Guard firewall to filter injection attempts.
Example use cases
Discovering SEC filing tools for agent
“I need to find any indexed MCP servers or A2A tools that can fetch SEC filings or EDGAR data — search the swarm router for 'SEC filings' and tell me what's available.”
Routing to a context compression tool
“Search the swarm router for tools that do context compression or token reduction — I want to find the best MCP endpoint I can route my agent through to shrink my prompt payloads.”
Verifying a specific tool endpoint
“I have this endpoint URL for a GitHub security auditor — can you check the swarm router to verify it's indexed and safe to call?”
Technical details
Endpoint
POSThttps://hn-pulse.agentdiet.dev/v1/swarm-router?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 maintaining its own registry, or when you want a single connection point that safely proxies to hundreds of tool providers with built-in token compression and prompt injection protection. Ideal for meta-orchestration scenarios where the specific downstream tool is not known in advance.
Side effects
- Query too vague returns zero or low-relevance tool matches
- Endpoint URL verification fails if the URL is not indexed in the 500+ server registry
- Prompt-Guard firewall may block queries containing injection-like patterns
- Downstream MCP server unavailability causes routing failures
- Payment not processed (HTTP 402) if x402 micropayment is not configured correctly
