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/tool-broker)
Output
Returns a compressed (up to 85% token reduction) list of matching MCP servers and A2A tools relevant to the query, including metadata about each tool, filtered through the Prompt-Guard firewall to remove malicious or unsafe tool descriptors.
Example use cases
Agent swarm tool routing
“My agent swarm needs to process GitHub security audits — can you search the MCP index for tools that handle GitHub security and return the best matching servers?”
Capability discovery for new agent
“I'm building a new AI agent and need to know which MCP servers support context compression and prompt firewall protection — search the tool broker for those capabilities.”
Find DEX intelligence tools
“Search the tool index for any MCP or A2A tools that can give me DEX token intelligence or on-chain risk analysis for my trading agent.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/tool-broker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover new tools or MCP servers at runtime rather than using a hardcoded tool list; especially valuable when searching across a broad index of 500+ tools with token-efficient results and built-in safety filtering.
Side effects
- Empty query string returns validation error
- No matching tools found for niche capability queries
- Firewall blocks results if query triggers prompt injection heuristics
- Upstream MCP servers temporarily unavailable leading to partial results
- Payment not completed (HTTP 402) blocks access to results
