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/b2b-osint-dag)
Output
Returns a list of matching MCP servers or A2A tools ranked by relevance to the query, along with capability metadata, endpoint URLs, and token-compressed summaries. If a URL is supplied, returns validation and safety assessment of that endpoint.
Example use cases
Discovering SEC filing tools for an agent
“I'm building a financial research agent and need to find which MCP servers or A2A tools handle SEC filings and company financial data — can you search the tool index for 'sec filings' and tell me what's available?”
Swarm routing for a multi-agent pipeline
“I need to wire up a multi-agent swarm and want a single connection point that can route to the right tool depending on the task — search the meta-router for 'company enrichment' and 'email verification' tools so I can configure my swarm.”
Verifying a third-party endpoint before calling it
“Before my agent calls this endpoint at https://some-mcp-server.example.com/api/tool, can you run it through the tool discovery router to verify it's legitimate and check if there's a safer proxied version available?”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/b2b-osint-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which MCP server or A2A tool is best suited for a given task without knowing the tool landscape in advance, or when you want a single proxied entry point with prompt-injection protection across 500+ tools. Prefer it over direct tool calls when operating in multi-agent swarms that need dynamic routing or when token budget is constrained and 85% compression is valuable.
Side effects
- Empty or too-generic query returns low-confidence or empty results
- Unknown or malformed endpoint URL returns validation failure
- Rate limiting or payment failure (HTTP 402) if x402 payment not attached
- Query for a niche capability not indexed returns no matches
- Network timeout if the meta-router is aggregating many upstream sources
