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/agent-tool-marketplace)
Output
Returns a list of matched MCP servers and A2A tools relevant to the query, with compressed metadata (85% token reduction), safety-filtered through a Prompt-Guard firewall, including endpoint details, capability descriptions, and routing information.
Example use cases
Discover tools for lead enrichment
“Search the MCP tool marketplace for any agent tools that can do B2B lead enrichment or company data lookups — I want to find all available options before wiring one into my workflow.”
Route agent to GitHub security capability
“Find me an MCP server or A2A tool that handles GitHub security audits — I need to plug one into my swarm so it can automatically scan repos for vulnerabilities.”
Verify endpoint before integration
“Can you check the tool marketplace to see if there's a registered A2A endpoint at https://whale-momentum.agentdiet.dev/v1/sec-edgar and whether it's compliant?”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/agent-tool-marketplace?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or route to MCP servers or A2A tools dynamically without hardcoding individual tool URLs — especially useful for swarm orchestration, building meta-agents, or when you need to search across 500+ tools with a single compressed query rather than managing individual connections to each tool provider.
Side effects
- Empty query string returns validation error (minLength:1 required)
- Query matches no indexed tools — returns empty result set
- Upstream MCP server index unavailable — service timeout
- Payment required error (HTTP 402) if x402 micropayment not provided
- Malformed query triggers firewall rejection
