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/defi-token-due-diligence)
Output
A structured response listing matching MCP servers and A2A tool endpoints from the 500+ tool index, including their capabilities, metadata, and routing information, filtered through a Prompt-Guard firewall for safety.
Example use cases
Agent capability scouting for a workflow
“I'm building a multi-agent pipeline and need to find MCP tools that do context compression and GitHub security audits — can you search the tool index and tell me what's available?”
Endpoint URL verification before integration
“Before I connect my agent to https://agentdiet.dev/v1/workflows/defi-token-due-diligence, can you run it through the tool discovery index to verify it's a real, indexed endpoint?”
Discovering on-chain risk analysis tools
“I need to route my swarm to an agent that handles on-chain token risk — search the MCP index for tools that can do DeFi due diligence or smart contract security.”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/workflows/defi-token-due-diligence?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover and route to specialized MCP servers or A2A tools without pre-hardcoding integrations. Ideal for swarm orchestration, tool-of-tools patterns, or when building meta-agents that need to find the right capability at runtime. Prefer this over maintaining a static tool registry when the tool landscape changes frequently or when you need 500+ tools accessible through a single connection with built-in prompt safety.
Side effects
- Empty or too-broad query returns low-relevance or no results
- Query string too short (minLength:1 not meaningful enough) returns generic matches
- Endpoint URL verification query returns no match if URL is not indexed
- Response schema is generic object — structure of results may vary
- Payment not completed (HTTP 402) blocks access to results
- Rate limiting or quota exhaustion for repeated identical queries
