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://workflows.agentdiet.dev/api/mcp/audit)
Output
Returns a compressed (85% token reduction) list of matching MCP servers or A2A tools relevant to the query, including capability metadata, safety scores from the Prompt-Guard firewall, and endpoint verification status where a URL was provided.
Example use cases
Discovering SEC filing tools for agent
“I need to find MCP servers or A2A tools that can pull SEC filings for public companies — search the tool index for 'sec filings' and tell me what's available.”
Verifying safety of unknown MCP endpoint
“Before my agent connects to this MCP endpoint https://some-server.example.com/mcp, can you check if it's safe and legitimate using the tool discovery firewall?”
Finding company enrichment capabilities
“My agent needs to enrich leads with company data — search the A2A and MCP tool index for 'company enrichment' and return the best options with compressed metadata.”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/api/mcp/audit?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 when operating in a swarm or multi-agent environment where token efficiency matters. Ideal when you need a single connection to scan 500+ tools rather than maintaining individual integrations, and when you want built-in prompt-injection firewall screening before routing to third-party tools.
Side effects
- Empty query string returns validation error
- No matching tools found for obscure or niche capability queries
- Endpoint URL verification may fail if target is unreachable
- Compressed results may omit edge-case tool metadata
- Rate limiting or payment failure at $0.01/call threshold
