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 a structured object containing matching MCP servers and A2A tool entries relevant to the query, with metadata compressed by up to 85% and filtered through a Prompt-Guard firewall to prevent injection attacks. May include endpoint URLs, capability descriptions, and routing recommendations.
Example use cases
Discover tools for SEC filing research
“Search the MCP tool index for 'SEC filings' and show me what servers are available — I need something I can plug into my research agent for pulling company financial disclosures.”
Find a safe proxy for GitHub code auditing
“Look through the A2A and MCP tool registry for 'github security' — I want a firewall-filtered, token-compressed result so my swarm agent can safely audit repos without hitting rate limits.”
Route agent to company enrichment capability
“Search the tool index for 'company enrichment' and tell me which MCP servers or A2A endpoints are available — I'm building an agent pipeline that needs B2B lead data.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover the best available MCP server or A2A tool for a given capability at runtime, rather than hard-coding integrations. Especially useful when building multi-agent swarms that must route tasks to appropriate specialized tools, or when you need firewall-filtered proxying to prevent prompt injection from untrusted tool responses. Prefer over direct MCP server connections when token budget is constrained and 85% compression is valuable.
Side effects
- Empty result set if no MCP servers match the query string
- Query too vague returns low-confidence or irrelevant tool listings
- Endpoint URL verification fails if the target is offline or non-compliant
- HTTP 402 payment required if credit balance is insufficient
- Timeout if the meta-index is temporarily unavailable
- Prompt injection attempt detected and blocked by Prompt-Guard firewall
