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://shopify-spy.agentdiet.dev/v1/b2b-osint-dag)
Output
Returns a compressed, Prompt-Guard-filtered list of matching MCP servers or A2A tools relevant to the search query, including tool metadata and routing information, with approximately 85% token compression applied.
Example use cases
Discovering tools for SEC filings
“Search the MCP tool index for anything that handles SEC filings or financial document retrieval — I want to know what agent-ready tools are available for that.”
Verifying a specific endpoint URL
“Can you check whether this endpoint URL is indexed and verified in the MCP tool directory: https://example.agentdiet.dev/v1/some-tool”
Finding GitHub security audit tools
“Find me MCP servers or A2A tools that do GitHub repository security audits — I need something that checks licenses, dependencies, and supply chain risk.”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/b2b-osint-dag?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability, rather than hardcoding tool references. Especially useful for swarm-routing scenarios where the right downstream tool is unknown at build time, or when validating whether a specific endpoint URL is indexed and safe to call.
Side effects
- Empty or too-generic query returns low-relevance results
- Query for an unindexed endpoint URL returns no match
- Prompt-Guard firewall may block or sanitize queries containing injection patterns
- Network or upstream index unavailability causes 5xx errors
- Malformed query string returns 400 validation error
