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://mcp-security.agentdiet.dev/v1/b2b-osint-dag)
Output
Returns a compressed, token-efficient list of matching MCP servers or A2A tools relevant to the capability query, including endpoint metadata and Prompt-Guard firewall validation status. Results reflect the index of 500+ registered tools with approximately 85% token compression applied.
Example use cases
Discovering tools for SEC filing analysis
“I need to find an MCP server that can pull SEC 10-K or 10-Q filings for public companies — can you search the tool index for 'SEC filings' and tell me what's available?”
Routing agent swarm to compression tools
“My agent pipeline is burning too many tokens. Search the meta-router for tools related to 'context compression' so I can add one to my swarm.”
Verifying a specific endpoint before use
“Before I connect my agent to this endpoint URL, can you run it through the MCP discovery router to verify it's indexed and safe to use?”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/b2b-osint-dag?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 at runtime, rather than hardcoding a specific tool. Ideal for swarm orchestration, agent-to-agent routing, or when building pipelines that need to self-assemble from available tools. Prefer this over direct tool calls when the right downstream tool is unknown or needs to be validated for safety before use.
Side effects
- Empty or too-generic query returns no matches or overly broad results
- Unrecognized endpoint URL returns no verification data
- Rate limiting or payment failure (x402) blocks the request
- Query for a very niche capability returns zero indexed tools
- Network timeout if the meta-router index is under heavy load
