Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router
Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router is a paid API for AI agents from alpha-stream.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Searches an index of 500+ MCP servers and A2A tools by capability query, returning compressed tool metadata through a prompt-injection-guarded proxy router.

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/api/mcp/audit)
Output
Returns a structured list of matching MCP servers or A2A tools from an index of 500+ entries, with token-compressed metadata and prompt-injection filtering applied. If a URL is supplied, returns verification and safety status for that specific endpoint.
Example use cases
Discover tools for SEC filing analysis
“Search the MCP tool index for any servers or A2A tools that can pull SEC filings — I want to route my research agent to the right one.”
Find GitHub security audit capabilities
“Can you search the agent tool directory for anything related to GitHub security auditing or code vulnerability scanning? I need to find an MCP server I can connect to.”
Verify a specific MCP endpoint before use
“Before I connect my agent to https://some-mcp-server.example.com, can you check if it's indexed in your directory and flagged as safe to proxy?”
Technical details
Endpoint
GEThttps://alpha-stream.agentdiet.dev/api/mcp/audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool to use for a given capability, rather than hard-coding a single tool. Especially useful when building swarm or multi-agent systems that need to route tasks to the most appropriate tool at runtime, or when you want prompt-injection filtering (Prompt-Guard firewall) applied before proxying to an external tool.
Side effects
- Missing or empty query parameter returns a validation error
- Query returns zero results if no indexed tools match the capability
- Endpoint URL verification may fail if the target is unreachable or not indexed
- Token compression artifacts may reduce fidelity of tool descriptions for highly technical schemas
- Service may be unavailable if the underlying meta-router index is offline
