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-spy.agentdiet.dev/v1/mcp-gateway)
Output
Returns matching MCP server or A2A tool references relevant to the search query, with compressed metadata about each discovered capability, including routing information and tool descriptions, filtered through a prompt-injection firewall.
Example use cases
Discovering tools for GitHub security audits
“Search across all indexed MCP servers for something that can do GitHub security auditing or code vulnerability scanning — I want the best available tool routed to my agent.”
Finding on-chain risk analysis tools
“I need to find an A2A or MCP tool that handles on-chain risk or DEX token intelligence — can you query the meta-router and tell me what's available?”
Routing agent to email verification capability
“Search the MCP tool index for an email verification or domain OSINT capability so I can wire it into my workflow.”
Technical details
Endpoint
POSThttps://shopify-spy.agentdiet.dev/v1/mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool can handle a given capability at runtime, rather than hardcoding tool references. Best when the agent's tool requirements are not known in advance, or when orchestrating swarms of agents that need to self-select appropriate sub-tools. Preferable to manual tool registries when operating across 500+ tools and needing a single-connection interface with built-in safety filtering.
Side effects
- Empty or vague query returns no relevant tools
- Query matches too many tools leading to noisy results
- Indexed tool is stale or no longer available at its original endpoint
- Token-compressed response may omit details needed for full integration
- Payment (x402) failure if USDC balance is insufficient
