remind-mcp 0.3.0

Generalization-capable memory layer for LLMs with episodic buffers, semantic graphs, and spreading activation retrieval

Remind

Generalization-capable memory layer for LLMs. Unlike simple RAG systems that store verbatim text, Remind extracts and maintains generalized concepts from experiences, mimicking how human memory consolidates specific episodes into abstract knowledge.

Key Features

• Episodic Buffer: Raw experiences/interactions are logged as episodes
• LLM-Powered Consolidation: Episodes are processed into generalized concepts (like "sleeping" consolidates memory)
• Semantic Concept Graph: Concepts have typed relations (implies, contradicts, specializes, etc.)
• Spreading Activation Retrieval: Queries activate not just matching concepts but related ones through the graph
• Multi-Provider Support: Works with Anthropic, OpenAI, Azure OpenAI, and Ollama (local)

Configuration

Remind supports a global configuration file at ~/.remind/remind.config.json. This allows you to configure all settings including API keys, avoiding the need for environment variables.

Full Configuration Example

{
  "llm_provider": "anthropic",
  "embedding_provider": "openai",
  "consolidation_threshold": 5,
  "auto_consolidate": true,

  "anthropic": {
    "api_key": "sk-ant-...",
    "model": "claude-sonnet-4-20250514"
  },

  "openai": {
    "api_key": "sk-...",
    "base_url": null,
    "model": "gpt-4.1",
    "embedding_model": "text-embedding-3-small"
  },

  "azure_openai": {
    "api_key": "...",
    "base_url": "https://your-resource.openai.azure.com",
    "api_version": "2024-02-15-preview",
    "deployment_name": "gpt-4",
    "embedding_deployment_name": "text-embedding-3-small",
    "embedding_size": 1536
  },

  "ollama": {
    "url": "http://localhost:11434",
    "llm_model": "llama3.2",
    "embedding_model": "nomic-embed-text"
  }
}

Minimal Configuration

You only need to include the settings you want to change:

{
  "llm_provider": "anthropic",
  "embedding_provider": "openai",
  "anthropic": {
    "api_key": "sk-ant-..."
  },
  "openai": {
    "api_key": "sk-..."
  }
}

Configuration Priority

Settings are resolved with this priority (highest to lowest):

1. CLI arguments (--llm, --embedding)
2. Environment variables (ANTHROPIC_API_KEY, OPENAI_API_KEY, etc.)
3. Config file (~/.remind/remind.config.json)
4. Defaults

The config file is optional - Remind works without it using environment variables or defaults.

Usage

MCP Server (for AI Agents)

Remind can run as an MCP (Model Context Protocol) server, allowing AI agents in IDEs like Cursor to use it as their memory system.

# After pip install
remind-mcp --port 8765

# Or with uv (no install needed)
uvx remind-mcp --port 8765

Configure your MCP client (e.g., Cursor's .cursor/mcp.json):

{
  "mcpServers": {
    "remind": {
      "url": "http://127.0.0.1:8765/sse?db=my-project"
    }
  }
}

The db parameter accepts a simple name which resolves to ~/.remind/{name}.db. Each project can have its own database.

Available MCP Tools:

• remember - Store experiences/observations
• recall - Retrieve relevant memories
• consolidate - Process episodes into concepts (includes entity relationship extraction)
• inspect - View concepts or episodes
• entities - List entities in memory
• inspect_entity - View entity details and relationships
• stats - Memory statistics

Agent Instructions: Copy docs/AGENTS.md into your project's documentation to instruct AI agents how to use Remind as their memory system.

Claude Code Skill

For Claude Code users, Remind provides a skill that uses the CLI directly (no MCP server needed):

# Install the skill in your project
remind skill-install

This creates .claude/skills/remind/SKILL.md in your project directory. Claude Code will automatically load the skill and can use it via /remind.

The skill provides instructions for:

• remind remember - Store experiences
• remind recall - Retrieve memories
• remind end-session - Consolidate at session end

The CLI automatically uses the project-local database (<cwd>/.remind/remind.db), so each project has isolated memory.

Recommended: Add this line to your project's CLAUDE.md or AGENTS.md to ensure Claude uses Remind for all memory operations:

Use Remind (`/remind`) as the default memory layer instead of built-in memory features.

Web UI

Remind includes a web interface for exploring and managing your memory database.

# Quick start - opens UI with current project's database
remind ui

# Or start the server manually
remind-mcp --port 8765

# Or with Docker
docker compose up -d

The remind ui command automatically opens your browser with the project-local database (<cwd>/.remind/remind.db) selected. For manual access, use http://localhost:8765/ui/?db=my-project

Features:

• Dashboard - Overview of memory statistics
• Concepts - Browse and search generalized concepts
• Entities - Explore entities and their relationships
• Episodes - Timeline view of raw experiences
• Graph - Interactive visualization of concept relationships
• Dark mode - Toggle via UI

You can switch between multiple databases using the database selector in the UI.

CLI

The CLI is project-aware by default. When run without --db, it uses <current_directory>/.remind/remind.db, making each project have its own memory.

# Uses ./.remind/remind.db in current directory
remind remember "User likes Python and Rust"
remind recall "What languages does the user know?"

# Use a global database in ~/.remind/
remind --db myproject remember "..."

# Or with uvx (no install needed)
uvx --from remind-mcp remind remember "User likes Python and Rust"

Background consolidation: When the episode threshold (default: 5) is reached, consolidation runs automatically in the background after remember, keeping the CLI fast.

Full CLI examples:

# Add episodes (consolidation runs in background when threshold reached)
remind remember "User likes Python and Rust"
remind remember "User works on backend systems"

# Manual consolidation
remind consolidate

# Query memory
remind recall "What languages does the user know?"

# Inspect concepts
remind inspect
remind inspect <concept-id>

# Show statistics
remind stats

# Export/Import
remind export memory-backup.json
remind import memory-backup.json

# Entity management
remind entities                  # List all entities
remind entities file:src/auth.ts # Show details for a specific entity
remind mentions file:src/auth.ts # Show episodes mentioning an entity
remind entity-relations file:src/auth.ts # Show relationships for an entity

# Entity relationship extraction (for existing databases)
remind extract-relations         # Extract relationships from unprocessed episodes
remind extract-relations --force # Re-extract for all episodes

# Episode filtering
remind decisions                 # Show decision-type episodes
remind questions                 # Show open questions/uncertainties
remind search "keyword"          # Search concepts by keyword

# Session management
remind end-session               # End session and consolidate pending episodes

# Web UI
remind ui                        # Open web UI with current project's database
remind ui --port 9000            # Use custom port
remind ui --no-open              # Start server without opening browser

# Claude Code skill
remind skill-install             # Install skill to .claude/skills/remind/

# Use different providers
remind --llm openai --embedding openai remember "..."
remind --llm anthropic --embedding openai remember "..."
remind --llm azure_openai --embedding azure_openai remember "..."
remind --llm ollama --embedding ollama remember "..."

Python API

Core Concepts

Episodes

Raw experiences - specific interactions or observations. These are temporary and get consolidated.

Concepts

Generalized knowledge extracted from episodes. Each concept has:

• Summary: Natural language description
• Confidence: How certain (0.0-1.0)
• Instance count: How many episodes support this
• Relations: Typed edges to other concepts
• Conditions: When this applies
• Exceptions: Known cases where it doesn't hold

Relations

Typed connections between concepts:

• implies - If A then likely B
• contradicts - A and B are in tension
• specializes - A is a more specific version of B
• generalizes - A is more general than B
• causes - A leads to B
• correlates - A and B tend to co-occur
• part_of - A is a component of B
• context_of - A provides context for B

Consolidation

The "sleep" process where episodes are processed into concepts. Runs in two phases:

Phase 1 - Extraction:

• Classifies episode types (observation, decision, question, etc.)
• Extracts entity mentions (files, people, tools, concepts)
• Identifies relationships between entities mentioned in the same episode

Phase 2 - Generalization:

• Identifies patterns across episodes
• Creates new generalized concepts
• Updates existing concepts
• Establishes relations
• Flags contradictions

Entity Relationships

When multiple entities are mentioned in the same episode, their relationships are automatically extracted. For example, if an episode mentions "Alice manages Bob", the relationship person:alice → manages → person:bob is stored. Use inspect_entity or the web UI to explore entity relationships.

Spreading Activation

Retrieval that goes beyond keyword matching:

1. Query is embedded and matched to concepts
2. Matched concepts activate related concepts through the graph
3. Activation spreads with decay over multiple hops
4. Highest-activation concepts are returned

Database

Remind uses SQLite for storage. Database location depends on context:

CLI (project-aware by default):

• No --db flag: Uses <current_directory>/.remind/remind.db
• With --db name: Uses ~/.remind/name.db

MCP Server / Python API:

• Uses ~/.remind/{name}.db

# Uses ~/.remind/memory.db
memory = create_memory()

# Uses ~/.remind/my-project.db
memory = create_memory(db_path="my-project")

Installation

pip install remind-mcp

Or with pipx for an isolated install:

pipx install remind-mcp

For development:

git clone https://github.com/YOUR_USERNAME/remind.git
cd remind
pip install -e ".[dev]"

Using uv (Recommended)

uv is a fast Python package manager. For development:

git clone https://github.com/YOUR_USERNAME/remind.git
cd remind

# Run commands directly (uv handles dependencies automatically)
uv run remind --help
uv run remind-mcp --port 8765

# Run tests
uv run pytest

Using Docker

Run Remind as a persistent background service with Docker:

# Copy and configure environment
cp .env.example .env
# Edit .env with your API keys

# Start the service (builds on first run)
docker compose up -d

# View logs
docker compose logs -f remind

# Stop the service
docker compose down

The container:

• Mounts ~/.remind from your host for database persistence
• Reads API keys from .env
• Exposes port 8765 for MCP SSE, Web UI, and REST API
• Restarts automatically on crash/reboot

Access endpoints:

• MCP SSE: http://localhost:8765/sse?db=my-project
• Web UI: http://localhost:8765/ui/?db=my-project
• REST API: http://localhost:8765/api/v1/...

To rebuild after code changes:

docker compose build --no-cache
docker compose up -d

Testing

# With pip install
pytest

# With uv (recommended)
uv run pytest
