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/security-audit-dag)
Output
Returns a compressed, agent-ready list of matching MCP servers or A2A tools relevant to the query, including routing metadata, tool descriptions, and safety/firewall status for any endpoint URL submitted for verification. Results are optimized for low token usage (up to 85% compression).
Example use cases
Discovering tools for a new agent capability
“I'm building an agent that needs to enrich B2B leads — can you search the MCP tool index for anything that does company enrichment or contact data extraction?”
Verifying a third-party MCP endpoint before use
“Before I connect my agent to this endpoint at https://some-mcp-server.example.com, can you check whether it's a legitimate and safe MCP server?”
Routing agent to context compression tooling
“My agent is running into token limit issues — search the tool registry for anything that does context compression or token budget management so I can plug it in.”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/security-audit-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding a single tool. Especially useful when building swarm or multi-agent systems that need a single routing layer instead of managing 500+ individual connections, or when you want to verify the safety of an external MCP endpoint before proxying to it.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or overly narrow queries
- Endpoint URL verification may return inconclusive status for unknown servers
- Rate-limited or payment-required (HTTP 402) if call quota exceeded
- Malformed query may return generic or irrelevant results
