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://agentdiet.dev/v1/workflows/b2b-lead-enrichment)
Output
Returns a structured object listing matching MCP servers or A2A tool descriptors relevant to the capability query, with compressed context (up to 85% token reduction) and prompt-guard filtered results. May also include verification status if an endpoint URL is submitted as the query.
Example use cases
Discovering tools for SEC filing retrieval
“I need to find MCP servers or A2A tools that can pull SEC filings — can you search the tool index for 'sec filings' and tell me what's available?”
Finding a GitHub security audit agent
“Search the MCP ecosystem for any agents or servers that do GitHub security audits — I want to see what tools index under 'github security' before I build my workflow.”
Verifying an endpoint is indexed and reachable
“Can you check whether the endpoint at https://agentdiet.dev/v1/workflows/b2b-lead-enrichment is in the MCP tool index and compliant?”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/workflows/b2b-lead-enrichment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP servers or A2A tools support a given capability, rather than hardcoding tool references. Especially useful when building multi-agent swarms that need to route tasks to specialized sub-agents, or when verifying that a known endpoint URL is indexed and reachable. The 85% token compression makes it suitable for context-constrained agents.
Side effects
- Empty query string returns validation error (minLength:1 not met)
- No matching tools found for niche or misspelled capability query
- Endpoint URL verification fails if the target is offline or non-compliant
- Response schema is generic object — downstream parsing may require defensive handling
- Service may return stale index data if 500+ tool catalog is not freshly synced
