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/execute)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, with compressed capability descriptions (up to 85% token reduction), safety-filtered through a Prompt-Guard firewall, and optionally verification status for a submitted endpoint URL.
Example use cases
Discovering tools for GitHub security audits
“Search the agent tool index for MCP servers or A2A tools that can audit GitHub repositories for security vulnerabilities — I need something that works with the swarm router.”
Finding context compression capabilities
“Can you look through the MCP tool directory and find me tools that specialize in context compression or token reduction for large language model prompts?”
Routing to company enrichment tools
“I need to find which MCP servers or A2A agents in the index can do B2B company enrichment or tech stack analysis — search for 'company enrichment' and tell me what's available.”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability without hardcoding integrations. It is especially useful when building swarm orchestration systems, needing a single connection point to hundreds of tools, or when token efficiency and prompt-injection safety are priorities.
Side effects
- No matching tools found for obscure or highly specific queries
- Endpoint URL verification may time out for slow or offline targets
- Query too vague returns overly broad results with low relevance
- Rate limiting or payment failure at $0.01/call threshold
- Prompt-Guard firewall may block queries containing injection-like patterns
