helio

Governance proxy for MCP: block or hold AI agent tool calls on their arguments, route approvals with the arguments shown, enforce rules the model cannot argue with, require prerequisites, cap cumulative spend across tools and servers, and audit every call. No changes to agent code or MCP servers.

      ]

Known working client config (can write into mcp.json):

  "mcpServers": {
    "helio": {
      "command": "npx",

Please: 1) check README for deps and env vars; 2) write config for my client; 3) if secrets are missing, tell me what to fill — do not invent values.
