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://github-audit.agentdiet.dev/v1/b2b-osint-dag)
Output
Returns a list of matching MCP servers or A2A tools from the 500+ item index, with token-compressed capability descriptions, endpoint URLs, and metadata about each matching tool, filtered through a Prompt-Guard firewall.
Example use cases
Discover GitHub audit tools for agent
“Search for MCP servers or A2A tools that can do GitHub security audits and code repository analysis — show me what's available in the index.”
Find SEC filings data endpoints
“I need to route my agent to a tool that handles SEC filings and financial document retrieval — can you search the MCP index for matching capabilities?”
Locate B2B company enrichment tools
“Find me any MCP servers in the tool index that support B2B lead enrichment or company OSINT so I can wire them into my agent pipeline.”
Technical details
Endpoint
GEThttps://github-audit.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 exist for a given capability rather than hardcoding tool endpoints. It is especially useful when building meta-agents or swarms that need to self-configure their tool access, or when you want to verify whether a specific endpoint URL is indexed and compliant.
Side effects
- No matching tools found for the query string — returns empty result set
- Query too vague or short triggers validation error (minLength:1 enforced)
- Upstream MCP server index unavailable — returns service error
- Payment not authorized via x402 — returns HTTP 402 before processing
- Prompt injection detected by firewall — request blocked with security notice
