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://domain-osint.agentdiet.dev/v1/swarm-router)
Output
Returns matched MCP server or A2A tool metadata including endpoint details, capability descriptions, and compressed schema representations, filtered through the Prompt-Guard firewall for safety.
Example use cases
Discovering MCP tools for GitHub audits
“Search through your MCP tool index for anything that can do GitHub security audits or code scanning — I need to wire the best-matching server into my agent pipeline.”
Finding a prompt-safe proxy for external tools
“I need to call an external A2A tool but want it passed through a prompt-injection firewall first — find me the right safe-proxy endpoint in the swarm router for handling untrusted content.”
Locating token-efficient context compression tools
“Search the swarm router for MCP servers that support context compression — I want to cut down token usage in my agent workflows by at least 80%.”
Technical details
Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/swarm-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover the right MCP server or A2A tool from a large index without maintaining its own registry, especially when token efficiency matters or when prompt-injection safety is required before routing to external tools.
Side effects
- Empty or vague query returns no matches or low-confidence results
- Queried capability not indexed among the 500+ servers returns empty result set
- Endpoint URL verification fails if target is offline or non-compliant
- Rate limiting or payment failure (HTTP 402) if x402 credentials are missing or insufficient
- Firewall may reject queries containing prompt-injection patterns
