> Open source semantic memory system for Claude Code and AI coding assistants.

## Overview

succ provides 14 consolidated MCP tools with action parameters for persistent memory, hybrid code search, knowledge graph, structured debugging, and PRD pipelines. Everything runs local-first — no telemetry, no cloud dependency.

- succ_remember — store memories with auto-tagging and quality scoring
- succ_recall — recall memories with temporal and tag filters
- succ_forget — delete memories by id, age, or tag
- succ_dead_end — record failed approaches to prevent repeats
