What is Nelly?

Nelly is an MCP server that searches your past Claude Code session transcripts (JSONL files stored in ~/.claude/projects/) and helps you find and resume old conversations. It searches across ALL projects at once, regardless of which project you're currently working in.

Install

Terminal

npm install -g nelly-elephant-mcp

Add to ~/.claude/mcp_settings.json:

config.json

{
  "mcpServers": {
    "nelly": {
      "command": "nelly-elephant-mcp",
      "args": []
    }
  }
}

Tools

nelly_instructions: Returns usage guide, platform info, sessions directory status, and diagnostics
nelly_search: Keyword search across all past sessions. Supports max_results (1-100), days_back (1-3650), and project filter
nelly_context: Expanded context from a specific session — surrounding lines around matches
nelly_recent: Lists most recent sessions by modification time. Supports count (1-100) and project filter

Trunk Modes

Long Trunk: Conversational, character-driven — Nelly guides you with personality
Short Trunk: Just results. Date, project, snippet, resume command.

Say "Nelly long trunk" or "Nelly short trunk" to switch.

Privacy

Zero network calls. Zero telemetry. Zero data collection. Reads only local JSONL files via stdio transport. One runtime dependency: @modelcontextprotocol/sdk. MIT licensed.
