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/crypto-alpha-dag)
Output
Returns a filtered list of matching MCP servers or A2A tools relevant to the search query, with capability metadata, endpoint URLs, and token-compressed descriptions, all screened through the Prompt-Guard firewall.
Example use cases
Discover tools for on-chain risk
“Search the MCP index for any tools that cover on-chain risk or DEX token intelligence — I need to find the right server to route my crypto analysis tasks through.”
Find GitHub audit capabilities
“Look through the A2A and MCP tool registry for anything that can do GitHub security audits or code scanning — I want to wire my swarm agent to the best match.”
Route email verification tasks
“Search the tool discovery index for MCP servers that handle email verification or domain OSINT so I can connect my agent to the right capability.”
Technical details
Endpoint
POSThttps://shopify-spy.agentdiet.dev/v1/crypto-alpha-dag?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 novel task at runtime, especially when building swarm or multi-agent systems that need to self-route across 500+ indexed capabilities. Prefer it over hardcoded tool registries when token budget is tight (85% compression) or when prompt-injection safety across third-party tool responses is required.
Side effects
- Empty or too-generic query returns irrelevant or no results
- Query matches no indexed tools — empty result set returned
- Prompt-Guard firewall blocks results if injected content is detected in tool metadata
- Payment required (HTTP 402) if USDC credit is not pre-authorized
- Malformed query (missing required 'query' field) returns validation error
