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/broker/execute)
Output
Returns matching MCP server or A2A tool metadata, including endpoint URLs, capability descriptions, and routing recommendations, with responses compressed to reduce token usage. May include prompt-injection firewall status for discovered endpoints.
Example use cases
Finding a context compression tool
“I'm running low on tokens in my agent pipeline — can you search the MCP tool index for anything that handles context compression or token reduction?”
Routing a GitHub security audit query
“Find me an A2A or MCP tool that can run a GitHub security audit — search your index and tell me which endpoint to use.”
Discovering DEX token intelligence tools
“I need a tool that does DEX token intelligence or on-chain risk analysis — can you search through the MCP server directory and find the best match?”
Technical details
Endpoint
POSThttps://whale-momentum.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover the right tool from a large catalog of MCP servers and A2A tools without manually connecting to each one. Ideal for dynamic multi-agent pipelines where the required capability is not known in advance, or when token budget is constrained and compression is needed. Prefer over building a static tool registry when the tool landscape changes frequently.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or highly specific queries
- Rate limiting or payment failure with HTTP 402 if x402 micropayment is not attached
- Timeout if upstream MCP servers are slow to respond
- Idempotency-Key collision if reused UUIDv4 is submitted
