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://preflight.agentdiet.dev/v1/agent-router)
Output
Returns a compressed, ranked list of matching MCP servers and A2A tools with metadata about their capabilities, schemas, and routing information, filtered through a prompt-injection firewall to ensure safety — delivered with up to 85% token compression compared to raw tool manifests.
Example use cases
Discover tools for GitHub security audits
“Find me all the MCP servers or A2A tools in your index that handle GitHub security audits or code vulnerability scanning — I need to pick the best one for my agent pipeline.”
Route agent to context compression capability
“I need a tool that does context compression for my agent to reduce token usage — can you search your tool index and tell me what's available?”
Verify a specific MCP endpoint
“Can you check whether this endpoint URL is a valid and safe MCP server before I connect my agent to it: https://some-mcp-server.example.com/tools”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/agent-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover the right tool or MCP server for a capability without hardcoding integrations — especially valuable in swarm/multi-agent architectures where the agent fleet needs to route tasks to specialized tools. Prefer this over manually curating tool lists when the tool landscape changes frequently or when you need prompt-injection safety screening built into discovery.
Side effects
- Empty query string returns validation error
- Query too vague returns low-confidence or empty results
- Endpoint URL verification returns unknown status if server is unreachable
- Rate limiting or payment failure returns 402 response requiring x402 USDC payment
- Firewall may flag and block results containing suspicious prompt-injection patterns
