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://llms-generator.agentdiet.dev/v1/b2b-osint-dag)
Output
Returns a ranked list of matching MCP servers or A2A tool endpoints that satisfy the capability query, including tool metadata and routing information, with 85% token-compressed descriptions and filtered through a Prompt-Guard firewall to block malicious content.
Example use cases
Find tools for developer security audits
“Search the A2A and MCP tool index for any servers that handle GitHub security audits or code vulnerability scanning — I want to route my agent to the best available option.”
Discover email verification MCP servers
“Can you query the meta-router to find me MCP servers that support email verification? I need to plug one into my lead enrichment pipeline.”
Route agent to on-chain risk tools
“Search the 500+ indexed MCP tools for anything related to on-chain risk or smart contract security so I can have my agent use the right endpoint automatically.”
Technical details
Endpoint
POSThttps://llms-generator.agentdiet.dev/v1/b2b-osint-dag?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to use for a given capability rather than hardcoding endpoint URLs. Prefer this over manual tool registries when you need to search across 500+ tools, when you want prompt firewall protection on routed calls, or when token budget is limited and you need compressed tool descriptions.
Side effects
- Empty or too-vague query returns no matches or overly broad results
- Query for a very niche capability not yet indexed returns empty result set
- Prompt-Guard firewall blocks queries that resemble injection attempts
- Payment not processed (HTTP 402) if x402 micropayment header is missing or invalid
- Timeout if the meta-router is querying many upstream MCP servers simultaneously
