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/a2a-router)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with compressed metadata (85% token reduction claimed), safety-filtered through a Prompt-Guard firewall, and optionally verification status for a given endpoint URL.
Example use cases
Swarm agent tool discovery
“I'm building a multi-agent pipeline and need to find MCP servers that handle SEC filings and GitHub auditing — can you search the tool index and give me the best matches?”
Safe proxy routing for unknown endpoints
“Before I connect my agent to this external MCP endpoint, can you check if it's already indexed and verified in the router so I know it's safe to call?”
Token-efficient capability lookup
“My agent is running low on context budget — can you search for tools that do domain OSINT and give me a compressed summary of what's available so I don't waste tokens loading full schemas?”
Technical details
Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool can fulfill a capability requirement, especially in token-constrained contexts or multi-agent swarm setups where vetting unknown endpoints for safety is important. It aggregates 500+ tools under a single connection, avoiding the need to maintain a bespoke tool registry.
Side effects
- Missing or empty 'query' parameter returns a 400 validation error
- Query matches no indexed tools — returns empty results set
- Queried endpoint URL not found in index — returns no verification result
- Service unavailable or rate-limited — returns 503 or 429
- Payment not processed (x402) — request blocked before routing
