@polytrackers/mcp-stdio

Stdio-to-HTTP bridge for PolyTrackers MCP clients that do not support remote Streamable HTTP directly.

Use it from MCP hosts with:

{
  "mcpServers": {
    "polytrackers": {
      "command": "npx",
      "args": ["-y", "@polytrackers/mcp-stdio"],
      "env": {
        "POLYTRACKERS_API_KEY": "ptk_..."
      }
    }
  }
}

Environment

• POLYTRACKERS_API_KEY is required.
• POLYTRACKERS_MCP_URL is optional and defaults to https://polytrackers.com/api/mcp.
• POLYTRACKERS_MCP_TIMEOUT_MS is optional and defaults to 60000.

POLYTRACKERS_MCP_URL must use https:// unless it targets a loopback host for local development. If POLYTRACKERS_MCP_ALLOWED_HOSTS is set, the configured URL host must be present in that comma-separated allowlist.

The bridge writes JSON-RPC frames only to stdout. Logs are single-line JSON on stderr.
