tibet-voice-cache-mcp 0.1.0

MCP server for tibet-voice-cache — give any AI client persistent voice conversation memory

tibet-voice-cache-mcp

MCP server for persistent voice conversation memory. Plug into Claude Code, Cursor, Windsurf, or any MCP client.

pip install tibet-voice-cache-mcp

What it does

Gives any MCP-compatible AI client tools to store and recall voice conversation context. User and AI utterances are stored separately in RAM (or optionally on disk) and formatted as clean context summaries — no fake turns, no role confusion.

Setup

Claude Code

// ~/.claude.json
{
  "mcpServers": {
    "voice-cache": {
      "command": "tibet-voice-cache-mcp"
    }
  }
}

With disk persistence

{
  "mcpServers": {
    "voice-cache": {
      "command": "tibet-voice-cache-mcp",
      "env": {
        "VOICE_CACHE_DIR": "/path/to/cache"
      }
    }
  }
}

Cursor / Windsurf

Same pattern — add tibet-voice-cache-mcp as an MCP server command.
