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://alpha-stream.agentdiet.dev/v1/security-audit-dag)
Output
A compressed list of matching MCP servers or A2A tool endpoints ranked by relevance to the query, with metadata about each tool's capabilities, connection details, and token-efficient descriptions filtered through the Prompt-Guard firewall.
Example use cases
Discover tools for SEC filing retrieval
“Search the MCP tool index for any agents or servers that can pull SEC filings or do financial document lookups — I want to see what's available and how to connect.”
Find email verification agents in the swarm
“I need to find MCP servers in the agentdiet index that support email verification or validation — search for 'email verification' and return the best matches.”
Route a prompt-safe query through the meta-router
“Look up tools in the A2A index that handle 'company enrichment' for B2B lead data, and make sure the results go through the Prompt-Guard firewall so I only get safe, vetted tools.”

Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/security-audit-dag?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover and route to MCP servers or A2A tools without maintaining its own index. It is especially valuable for swarm orchestration scenarios where token efficiency matters (85% compression) and when safety filtering via Prompt-Guard is required to prevent prompt injection from untrusted tool metadata.
Side effects
- Missing or empty 'query' parameter returns a 400 validation error
- Query matches zero tools in the index, returning an empty result set
- Endpoint URL verification input returns invalid or unreachable status
- Rate limiting or payment failure (HTTP 402) if x402 micropayment is not completed
- Firewall rejects query as potentially adversarial prompt injection
