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/crypto-alpha-dag)
Output
Returns a structured object listing matching MCP servers and A2A tools relevant to the capability query, with 85% token-compressed metadata, Prompt-Guard firewall filtering applied, and any relevant routing or proxy information for connecting to those tools.
Example use cases
Finding a GitHub security audit tool
“Search the tool discovery index for MCP servers or A2A agents that can do GitHub security audits — I need to know which ones are available and what they support.”
Discovering context compression agents
“I need to reduce my token usage — can you search the tool router for any MCP servers or agents that offer context compression capabilities?”
Locating on-chain crypto risk tools
“Find me any MCP or A2A tools indexed under on-chain risk or DEX token intelligence — I want to route my crypto analysis tasks to the right agent.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/crypto-alpha-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability, rather than hardcoding tool URLs. Especially useful for swarm orchestration scenarios where the right downstream tool is unknown at design time, or when you want firewall-filtered, token-compressed tool routing in a single connection.
Side effects
- Empty query string returns validation error (minLength:1 required)
- No matching tools found for obscure or misspelled capability query
- Prompt-Guard firewall blocks results flagged as adversarial or unsafe
- x402 payment failure if USDC balance is insufficient ($0.01/call)
- Upstream MCP server index temporarily unavailable returning empty or degraded results
