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/agent-router)
Output
Returns a token-compressed list of matching MCP servers or A2A tools relevant to the query, with routing metadata and safety filtering applied via Prompt-Guard firewall; also supports endpoint URL verification for compliance checks.
Example use cases
Discovering tools for financial data
“Search the agent tool index for any MCP servers or A2A endpoints that handle SEC filings or public company financial data — I want to wire one into my research agent.”
Finding a safe proxy for GitHub audits
“Find me any available MCP tools in the index that can do GitHub security auditing or code scanning, and make sure the results come through the prompt-guard firewall.”
Routing swarm agents to the right capability
“I'm building a multi-agent swarm and need to discover which tools in the 500+ MCP index handle on-chain risk analysis or DEX token intelligence — can you search for those capabilities?”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/agent-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools support a given capability at runtime, especially in swarm architectures where tool availability changes frequently; also useful when you want prompt-injection protection baked into the routing layer rather than handled separately.
Side effects
- Missing required 'query' parameter returns validation error
- Empty or overly broad query may return no matches or too many results
- Index may not reflect newly added MCP servers in real time
- Endpoint URL verification may time out if the target is unreachable
- HTTP 402 payment required if per-call credit is not provided
