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/v1/execute)
Output
Returns a compressed (up to 85% token reduction) listing of matching MCP servers or A2A tools, their capabilities, and routing metadata. For URL verification queries, returns status and validity of the given endpoint. Results pass through a Prompt-Guard firewall to block injected malicious instructions.
Example use cases
Discovering context compression tools
“Can you search the MCP tool registry for anything that does context compression or token reduction? I want to find the best available option and connect to it.”
Verifying a specific endpoint is live
“Check if this endpoint URL is valid and reachable through the A2A tool index: https://some-mcp-server.example.com/api — confirm it's active.”
Finding a GitHub security auditing agent
“Search through the 500+ indexed MCP servers and find me something that can do GitHub repository security audits — I want to route through it in one connection.”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover which of 500+ MCP servers or A2A tools supports a given capability, rather than hardcoding individual tool connections. Ideal for swarm architectures where agents must self-select tools at runtime. Also useful for verifying whether a specific tool endpoint is live before routing traffic to it.
Side effects
- Empty or too-broad query returns too many low-relevance results
- Requested tool category not indexed returns empty match set
- Endpoint URL verification fails if target server is offline
- Token compression may strip edge-case metadata for niche tools
- Rate limiting or payment failure (x402) if payment not attached correctly
