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/tool-search)
Output
A token-compressed, Prompt-Guard-filtered list of matching MCP servers and A2A tools from an index of 500+, including tool names, capability descriptions, and endpoint routing information relevant to the submitted query.
Example use cases
Finding a compression tool for agent context
“Search the tool index for 'context compression' — I want to find an MCP server my agent can use to shrink large payloads before sending them downstream.”
Discovering lead enrichment tools for B2B pipeline
“Look through the A2A and MCP tool registry for anything related to 'B2B lead enrichment' or 'company enrichment' — I'm building an agent that needs to fill in firmographic data automatically.”
Routing agent to on-chain risk capabilities
“Search for available A2A or MCP tools that handle 'on-chain risk' or 'DEX token intelligence' — my trading agent needs to find a safe proxy it can call for crypto risk signals.”
Technical details
Endpoint
POSThttps://shopify-intel.agentdiet.dev/v1/tool-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hard-coding tool URLs. It is especially useful in swarm or orchestrator architectures where the set of available tools is large and changing, and when token budget matters (85% compression). Prefer it over manual tool registries or static OpenAPI catalogs when you want a single connection to span 500+ tools with built-in prompt-injection protection.
Side effects
- Query too vague returns irrelevant or low-confidence matches
- Empty result set if no indexed tools match the capability query
- Payment required (HTTP 402) if x402 micropayment is not attached
- Prompt injection detected by firewall and request blocked
- Malformed query (missing required 'query' field) returns validation error
- Timeout if upstream tool index is temporarily unavailable
