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://agentdiet.dev/v1/security-audit-dag)
Output
Returns a list of matching MCP servers or A2A tools relevant to the query, including metadata about each endpoint, token-compressed summaries, security/firewall status, and routing recommendations. May also return verification results if an endpoint URL is provided as input.
Example use cases
Agent swarm tool discovery
“I'm building a multi-agent swarm and need to find which MCP servers support context compression and GitHub security auditing — can you search the tool index and give me the best matches?”
Verify and audit a suspicious endpoint
“I found this endpoint URL and want to check whether it's a legitimate, safe MCP tool before my agent calls it — can you run it through the discovery router to verify it?”
Route agent to SEC filings capability
“My agent needs to pull SEC filings for a company — can you search across all indexed A2A tools and MCP servers to find the right one to route this task through?”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/security-audit-dag?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool best matches a capability at runtime, rather than hardcoding tool connections. Particularly useful for swarm architectures that must route tasks to the right specialist tool, or when you want prompt injection firewall protection layered over external tool calls. Prefer over manual tool registries when you need to search across 500+ tools simultaneously with token-efficient responses.
Side effects
- Empty query string returns validation error
- Query matches no indexed tools — returns empty result set
- Endpoint URL provided for verification may be unreachable or not indexed
- Token compression or firewall layer may introduce latency spikes
- x402 payment failure if USDC balance is insufficient
- Overly broad queries may return too many low-relevance results
