Get Started in 30 Seconds

npm install -g squish-memory && squish install --all

That is it. Squish installs the CLI, starts the MCP server, and configures hooks for every coding agent it finds on your machine. No API keys. No config files. No Docker.

---

Pick Your Agent

Squish works with any MCP-compatible agent. Choose yours for a tailored quick start:

Claude Code

npm install -g squish-memory && squish install --all

Squish detects Claude Code and adds plugin hooks automatically. Your next session starts with full memory context. To verify:

squish context    # See what your agent remembers
squish stats      # Check memory health

Codex CLI (OpenAI)

Add Squish to your Codex MCP config:

{
  "mcpServers": {
    "squish": {
      "command": "squish-mcp",
      "args": ["--http", "--port", "8767"]
    }
  }
}

Codex now has persistent memory across sessions. Ask it "what did we decide about the database?" and it will recall your past decisions.

Cursor / Windsurf / Cline

Add the same MCP server block to your editor's MCP settings. One memory server, shared across all your editors and CLI agents.

OpenCode

squish install --all

OpenCode gets both MCP tools and auto-capture hooks. Decisions, constraints, and preferences are captured as you work.

Any MCP Client

{
  "mcpServers": {
    "squish": {
      "command": "squish-mcp",
      "args": ["--http", "--port", "8767"],
      "env": {
        "SQUISH_DB_PATH": "./squish-data"
      }
    }
  }
}

What Just Happened

After install, Squish runs in the background. Here is what it does:

1. Captures -- As you work, Squish watches for decisions, constraints, preferences, and context. It filters noise and stores what matters.
2. Ingests -- Drop files into the inbox directory. Images, audio, video, and documents are automatically extracted, described, and stored as searchable memories.
3. Stores -- Memories go into a local SQLite database with AES-256-GCM encryption. Nothing leaves your machine.
4. Retrieves -- When your agent starts a new session, Squish injects only the relevant memories (50-200 tokens, not 2,000).
5. Decays -- Old, low-value memories fade automatically. Your agent stays focused on what matters now.

squish remember "We chose PostgreSQL for the main datastore" --type decision
squish recall "database decisions"
squish sessions search "postgres migration"

Why Squish

Most memory tools need a second LLM for embeddings and retrieval. That means extra API costs, latency, and infrastructure you have to manage.

Squish uses local embeddings by default. Zero LLM dependency. 1-5ms latency. $0 runtime cost in local mode.

Features

Memory Intelligence

• Auto-captures decisions, constraints, and preferences as you work
• Restores relevant context when an agent restarts
• Handles contradictions and temporal facts with expiration
• Graph-boosted retrieval connects related memories across sessions
• Contradiction detection flags conflicting information
• Temporal reasoning tracks when facts were true vs. now
• Confidence scoring adjusts memory relevance over time
• Decay system automatically ages low-value memories

Multimodal Memory

• Ingest images, audio, video, and documents into searchable memories
• Automatic text extraction via OCR, speech-to-text, and document parsing
• 27+ supported file types: JPEG, PNG, GIF, WebP, TIFF, HEIC, MP3, WAV, OGG, FLAC, M4A, MP4, WebM, AVI, MOV, MKV, PDF, DOCX, XLSX, PPTX, TXT, MD, CSV, JSON, XML, YAML, HTML, RTF
• File watcher for automatic inbox monitoring and ingestion
• LLM-generated descriptions for each ingested file

FAQ

What is Squish?

Squish is a local-first memory runtime for AI coding agents. It gives your agents stable orientation, durable memory, and searchable session history across runs. Think of it as a brain that persists between sessions -- your agents remember decisions, constraints, preferences, and context without you having to re-explain everything.

Does Squish require an API key?

No. Squish works locally by default with zero API keys. It uses local embeddings (TF-IDF) and SQLite storage. You can optionally configure an external LLM for enhanced reasoning, but it is not required. An API key is only needed if you want to use the paid Squish Cloud for cross-device sync.

How does Squish compare to mem0 or agentmemory?

Squish is the only option that works locally with zero external dependencies. mem0 requires Qdrant (a vector database) and cloud API calls. agentmemory requires iii-engine. Squish uses SQLite and local embeddings by default. See the full comparison in the Why Squish section above.

Can I use Squish with multiple AI agents?

Yes. Squish works with any MCP-compatible agent. One memory server is shared across Claude Code, Cursor, Codex, Copilot, Gemini CLI, and any other agent that supports MCP. Memories are available to all connected agents.

Is my data private with Squish?

Yes. In local mode, all data stays on your machine in an encrypted SQLite database. Nothing is sent to any cloud service. AES-256-GCM encryption protects sensitive memories. In cloud mode, data is encrypted in transit and at rest.

What is the difference between recall and sessions?

squish recall searches your long-term memory -- distilled facts, decisions, and preferences that Squish has captured and organized. squish sessions search searches raw past agent runs -- the actual messages, commands, and file changes from previous Claude Code, Codex, or OpenCode sessions. Recall gives you what the system decided to remember. Sessions give you the evidence.
