Nelly the Elephant

spicyricecakes/nelly-elephant-mcp

Searches your local Claude Code session transcripts stored as JSONL files in ~/.claude/projects/ and lets you grep through past conversations across all projects at once. Exposes four tools: nelly_search for keyword queries with date and project filters, nelly_context for expanded snippets around matches, nelly_recent for browsing sessions by modification time, and nelly_instructions for diagnostics. Supports two output modes called "long trunk" and "short trunk" for conversational versus terse results. Runs entirely local with zero network calls or telemetry, just stdio transport reading your existing session files. Useful when you vaguely remember solving something weeks ago but can't remember which project or when.
