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/mcp-router)
Output
Returns a structured object containing matched MCP server or A2A tool entries relevant to the query, with token-compressed capability descriptions filtered through a Prompt-Guard firewall to prevent injection attacks. May also return compliance/verification status when an endpoint URL is provided as the query.
Example use cases
Discover tools for lead enrichment
“Can you search the MCP router for any tools that do B2B lead enrichment or company data lookups? I need to find what's available before I build my outreach pipeline.”
Find GitHub security audit tools
“Search the tool discovery index for MCP servers that can do GitHub security audits or code vulnerability scanning — list whatever's available with compressed descriptions.”
Verify a specific MCP endpoint
“Can you check whether this endpoint URL is a valid, compliant MCP server: https://some-agent-service.example.com/mcp — I want to confirm it's real before routing traffic to it.”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/mcp-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover new MCP or A2A tools at runtime rather than relying on a static tool registry. Especially useful for swarm architectures where agents need to self-route to the best available capability, or when you want prompt-injection protection built into the discovery layer. Prefer this over manually browsing MCP marketplaces or hardcoding tool lists.
Side effects
- Empty or vague query returns no relevant tool matches
- Unrecognized endpoint URL in verification mode returns null or error status
- Overly broad queries may return a large unfiltered list requiring downstream filtering
- Service may return stale index data if upstream MCP registries haven't been recently crawled
- HTTP 402 payment required if x402 credits are exhausted
