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://hn-pulse.agentdiet.dev/v1/agent-tool-marketplace)
Output
Returns a list of matching MCP servers and A2A tools from the 500+ index, with capability descriptions and endpoint metadata, compressed to reduce token usage, and filtered through a Prompt-Guard firewall to block malicious tool responses.
Example use cases
Discovering GitHub security audit tools
“Search the agent tool marketplace for any MCP servers or A2A tools that handle GitHub security audits or code scanning — I want to find what's available before I build my pipeline.”
Finding SEC filings retrieval tools
“Can you search the MCP index for tools that can pull SEC filings or EDGAR data? I need to find a ready-made agent tool I can route requests through.”
Locating context compression capabilities
“I need to find tools in the MCP ecosystem that support context compression or token reduction — search the tool discovery index for anything relevant and give me the top results.”
Technical details
Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/agent-tool-marketplace?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or search for MCP servers and A2A agent tools by capability without maintaining individual connections to hundreds of separate services. It is especially useful when you want token-efficient results from a broad ecosystem search, need a safe-proxied gateway with prompt injection protection, or want to verify whether a specific tool endpoint exists in the index.
Side effects
- Empty or vague query returns low-relevance or no results
- Query too broad returns overwhelming number of matches
- Endpoint URL verification query may return 404 if the tool is not indexed
- Rate limiting or payment failure (HTTP 402) if payment is not processed correctly
- Prompt-Guard firewall may block results flagged as unsafe
