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/broker/execute)
Output
Returns a matched set of MCP servers or A2A tools relevant to the query, with token-compressed responses (up to 85% reduction) and Prompt-Guard firewall applied to filter unsafe or injected content.
Example use cases
Discovering tools for on-chain risk analysis
“Search the tool index for any MCP servers or A2A tools that can do on-chain risk scoring or DEX token intelligence — I need to find the right one to plug into my crypto research agent.”
Finding a GitHub security audit tool
“Look through the MCP server index and find me any tools that handle GitHub security audits or code vulnerability scanning — I want to wire the best one into my CI pipeline agent.”
Routing a prompt injection firewall query
“Search the broker for any tools that scan for prompt injection or jailbreaks in untrusted web content — I need a safe-proxy option for my agent that reads external pages.”
Technical details
Endpoint
POSThttps://shopify-spy.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover and route to one of many MCP servers or A2A tools from a single connection point, especially when token efficiency matters or when you need prompt-injection protection on returned tool outputs. Prefer it over direct MCP connections when you don't know which specific server hosts a capability, or when building multi-tool swarm agents that need unified routing.
Side effects
- Query too vague — returns no matches or low-confidence tool listings
- Endpoint URL verification fails for unknown or offline MCP servers
- Payment not attached — x402 payment required error returned
- Rate limiting or idempotency key conflict on retries
- Tool index returns stale results if upstream MCP servers are offline
