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/x402-gateway)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, including compressed metadata about each tool's capabilities, endpoint URLs, and safety status from the Prompt-Guard firewall layer.
Example use cases
Discover tools for SEC filing research
“Search the MCP tool index for any agents or servers that handle SEC filings or company financial disclosures — I need to wire my agent up to something that covers that.”
Verify a suspicious endpoint URL
“Can you check whether this endpoint URL is registered and safe in the A2A tool directory: https://someagent.example.com/v1/tool — I want to make sure it's legitimate before routing traffic to it.”
Find context compression MCP servers
“Look up MCP servers in the meta-router that specialize in context compression or token reduction — I'm trying to cut down on LLM token costs in my swarm pipeline.”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/x402-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover new MCP servers or A2A tools at runtime, especially when the right downstream tool is not known in advance. Useful for swarm orchestration pipelines that need to route tasks to the best-fit agent tool from a large indexed catalog. Prefer this over hardcoded tool registries when you need breadth (500+ tools), token-efficient metadata, or built-in prompt-injection protection.
Side effects
- Empty query string returns validation error
- No tools match the search query — returns empty result set
- Endpoint URL verification fails if URL is not indexed
- Rate limiting or payment failure under x402 protocol returns 402 response
- Malformed query may return irrelevant or zero results
