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://hn-pulse.agentdiet.dev/v1/web-rag-shield-dag)
Output
Returns a compressed (up to 85% token reduction) list of matching MCP servers or A2A tools with capability descriptions, endpoint metadata, and Prompt-Guard firewall status — filtered for safety before delivery.
Example use cases
Finding tools for lead enrichment
“Search the tool index for 'company enrichment' — I need to find an MCP server that can fill in firmographic details for a list of B2B prospects.”
Discovering on-chain risk tools
“Look up what A2A or MCP tools are available for 'on-chain risk' so I can route my DeFi wallet analysis through something already indexed.”
Verifying a remote agent endpoint
“Can you check whether https://someagent.example.com/mcp is a valid, compliant MCP endpoint by running it through the tool discovery router?”
Technical details
Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/web-rag-shield-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover the right MCP server or A2A tool across a large index without maintaining dozens of separate connections — especially when token budget is constrained and prompt-injection safety filtering is required. Prefer it over manual tool registries when you need live, searchable coverage of 500+ tools in a single call.
Side effects
- Query too vague — returns no matches or low-relevance results
- Endpoint URL verification fails if the target is offline or non-compliant
- Rate limiting or payment failure (HTTP 402) if x402 micropayment is not properly configured
- Timeout if upstream MCP index is temporarily unavailable
- Overly broad query returns an unmanageable number of results
