EchoVault

Local memory for coding agents. Your agent remembers decisions, bugs, and context across sessions — no cloud, no API keys, no cost. Coding agents forget everything between sessions. They re-discover the same patterns, repeat the same mistakes, and forget the decisions you made yesterday. EchoVault gives your agent persistent memory that makes it better with every session.

Installation

Why EchoVault?

Local-first — Everything stays on your machine. Memories are stored as Markdown in ~/.memory/vault/, readable in Obsidian or any editor. No data leaves your machine unless you opt into cloud embeddings. MCP native — Runs as an MCP server exposing memory_save, memory_search, and memory_context as tools. Agents call them directly — no shell hooks needed. Zero idle cost — No background processes, no daemon, no RAM overhead. The MCP server only runs when the agent starts it. Hybrid search — FTS5 keyword search works out of the box. Add Ollama or OpenAI for semantic vector search. Cross-agent — Memories saved by Claude Code are searchable in Cursor, Codex, and OpenCode. One vault, many agents. Secret redaction — 3-layer redaction strips API keys, passwords, and credentials before anything hits disk. Supports explicit <redacted> tags, pattern detection, and custom .memoryignore rules. Obsidian-compatible — Session files are valid Markdown with YAML frontmatter. Point Obsidian at ~/.memory/vault/ and browse your agent’s memory visually.

How it works

~/.memory/
├── vault/                    # Obsidian-compatible Markdown
│   └── my-project/
│       └── 2026-02-01-session.md
├── index.db                  # SQLite: FTS5 + sqlite-vec
└── config.yaml               # Embedding provider config
  • Markdown vault — one file per session per project, with YAML frontmatter
  • SQLite index — FTS5 for keywords, sqlite-vec for semantic vectors
  • Compact pointers — search returns ~50-token summaries; full details fetched on demand
  • 3-layer redaction — explicit tags, pattern matching, and .memoryignore rules

​
Supported agents

EchoVault works with Claude Code, Cursor, Codex, and OpenCode. One command sets up the MCP config for your agent: 
memory setup claude-code   # or: cursor, codex, opencode
All agents share the same memory vault, so memories saved by one agent are available to all others.
