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://shopify-intel.agentdiet.dev/v1/agent-tool-marketplace)
Output
Returns a compressed index of matching MCP servers and A2A tool listings, including tool metadata, capability descriptions, routing suggestions, and any Prompt-Guard firewall flags, all delivered through a single connection with up to 85% token compression.
Example use cases
Discovering tools for on-chain risk
“Can you search the MCP tool marketplace for agents that handle on-chain risk analysis or DEX token intelligence? I want to see what's indexed there.”
Finding a GitHub security audit tool
“Look up what MCP servers or A2A tools are available for GitHub security audits in the agent tool marketplace — I need something I can plug into my swarm.”
Verifying an agent endpoint URL
“Can you check the agent tool marketplace to verify whether this endpoint URL is a known, compliant MCP or A2A tool: https://example-agent.dev/v1/tool?”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/agent-tool-marketplace?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover available MCP servers or A2A tools from a broad, curated index of 500+ options without maintaining its own tool registry. It is especially useful when token budget is a concern (85% compression), when safety filtering via Prompt-Guard is required before routing, or when building multi-agent swarms that need to self-configure from a live tool catalog.
Side effects
- Empty query string returns validation error (query is required, minLength 1)
- No matching tools found for the given capability query returns empty result set
- Endpoint URL verification for an unknown URL may return unverified or not-found status
- Upstream MCP servers unavailable may cause incomplete index results
- Payment failure via x402 may block access before results are returned
