Local MCP gateway in your system tray. Connect Claude Code, Cursor, and Codex to one endpoint, aggregate your MCP servers, and approve or deny tool calls with human-in-the-loop policy rules, OAuth 2.1 agent auth, OS keychain credentials, and a tamper-resistant audit log. Rust + Tauri.

Quick Install

Copy the config for your editor. Some servers may need additional setup — check the README.

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "prism": {
      "command": "cargo",
      "args": [
        "run",
        "--",
        "prism"
      ]
    }
  }
}

README Excerpt

**A local MCP gateway that lives in your system tray.** Point Claude Code, Cursor, Codex or any MCP client at one endpoint. Prism runs your MCP servers, aggregates their tools, and holds any call your rules mark as *ask* until you allow or deny it from the panel. Nothing leaves the machine. <p align="center">
