Installation

1. Install dependencies:

uv sync

2. Run the server:

uv run python server.py

3. Add to Claude Code MCP config (~/.config/claude/mcp.json):

{
  "servers": {
    "cc-session-search": {
      "command": ["uv", "run", "python", "server.py"],
      "cwd": "/path/to/cc-session-search"
    }
  }
}

list_sessions(project_name, days_back=7)

Lists sessions for a specific project within the specified time range.

list_recent_sessions(days_back=1, project_filter=None)

Lists recent sessions across all projects.

analyze_sessions(days_back=1, role_filter="both", include_tools=False, project_filter=None)

Extracts and analyzes messages from sessions with filtering options.

search_conversations(query, days_back=2, context_window=1, case_sensitive=False, project_filter=None)

Searches conversations for specific terms with context windows.
