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/a2a-router)
Output
Returns a list of matched MCP servers or A2A tools relevant to the capability query, including endpoint metadata, descriptions, and token-compressed representations. Results are screened through a prompt-injection firewall before being returned.
Example use cases
Discover tools for financial data
“Search the agent tool index for any MCP servers or A2A endpoints that can pull SEC filings or company financial data — I need to find what's available before building my research workflow.”
Route swarm to GitHub audit tools
“Find me all available MCP tools in the index that can do GitHub security audits or code vulnerability scanning so I can wire them into my autonomous swarm.”
Verify an endpoint before connecting
“Can you check the tool discovery router to verify whether this endpoint URL is a known, indexed A2A tool: https://example-mcp.dev/v1/enrich — I want to confirm it's legitimate before routing traffic to it.”
Technical details
Endpoint
POSThttps://shopify-spy.agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools are available for a given capability, especially in swarm or multi-agent architectures where you don't want to hardcode tool endpoints. Prefer it over manual tool registries when you need breadth (500+ indexed servers), built-in safety (prompt-injection firewall), and token efficiency (85% compression).
Side effects
- Empty or overly vague query returns no matches
- Query string too short (minLength: 1 violated) returns validation error
- Unknown or unindexed endpoint URL returns no match
- Service unavailability returns 402 or 5xx error
- Prompt-guard firewall may filter or reject malicious-looking queries
