Bossanova

Local MCP bridge for the Bossanova desktop vault (Windows and macOS): lets Claude Code, Codex CLI, Claude Desktop and ChatGPT use API keys and other secrets you approve, by sending an HTTPS request or launching a process on the AI's behalf, without the value ever going into the prompt. Four tools: bossanova_status, bossanova_fields, bossanova_send and bossanova_run.
