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/security-audit-dag)
Output
Returns a list of matching MCP servers or A2A tools from the 500+ indexed catalog, with compressed schema metadata, relevance ranking, and routing information. May include tool descriptions, endpoint URLs, capability tags, and safety status from the Prompt-Guard firewall.
Example use cases
Finding tools for SEC filings
“Search the MCP tool index for any agents or servers that can retrieve SEC filings or financial disclosures — I need to route my SEC research queries through the right tool.”
Discovering GitHub security audit tools
“Can you search the swarm router for MCP servers that handle GitHub security audits or code repository scanning? I want to find the best match from the indexed tools.”
Routing to context compression agents
“Look up tools in the A2A and MCP index that specialize in context compression — I want to reduce token usage in my agent pipeline and need to find something that routes efficiently.”
Technical details
Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/security-audit-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or route to the right MCP server or A2A tool from a large catalog without managing individual connections. It is especially useful when the target capability is unknown ahead of time, when you need token-efficient tool schemas, or when you want prompt injection protection built into the routing layer. Prefer alternatives if you already know the exact endpoint URL and want to call it directly.
Side effects
- Missing or empty query parameter returns validation error
- Query matches no indexed tools, returning empty result set
- Upstream MCP server or A2A endpoint is unreachable, causing partial results
- Prompt-Guard firewall flags query as potentially adversarial and blocks routing
- Rate limiting or payment failure (HTTP 402) prevents the call from completing
