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://whale-momentum.agentdiet.dev/v1/web-rag-shield-dag)
Output
Returns a compressed list of matching MCP servers and A2A tools from the meta-index, including capability descriptions, endpoint metadata, and routing information, filtered through a Prompt-Guard firewall to screen out malicious or non-compliant entries.
Example use cases
Finding an SEC filings agent
“Search the tool index for any MCP servers or A2A agents that can retrieve SEC filings — I need to route a financial research task to the right one.”
Discovering GitHub security audit tools
“Look through the 500+ indexed MCP tools and find me anything that does GitHub security auditing or code risk scanning — I want to pick the best option for my pipeline.”
Routing to a DEX token intelligence service
“Search the agent index for tools that do DEX token intelligence or on-chain risk analysis — I need to find and route to one for a crypto research workflow.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/web-rag-shield-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to invoke for a given capability, rather than hardcoding a specific tool. Especially useful for meta-orchestration, swarm routing, or when the target capability (e.g. SEC filings, email verification, GitHub audits) is not known in advance.
Side effects
- Empty query string returns validation error
- No matching tools found for niche or misspelled query
- Payment required (HTTP 402) if x402 credentials are missing or invalid
- Firewall may block results flagged as prompt-injection risks
- Index may not reflect very recently added MCP servers
