Amber — Claude Code MCP server: what it does, how to install
Provides long-term memory across sessions, storing decisions and project context. Useful when you need your assistant to recall details without manual tagging.
claude mcp add --transport http amber https://mcp.ambermem.comWhat Amber does
Amber runs as a remote service that stores atomic facts extracted during conversations. Instead of dumping raw chat logs, the assistant splits discussion points into discrete notes and generates at least five semantic variations for each. Embeddings are created via dedicated vector endpoints, keeping generative chat models away from raw memory contents.
Retrieval relies on a hybrid pipeline combining vector search with keyword matching via Reciprocal Rank Fusion. It handles informal time frames like "3 days ago" by parsing them into calendar ranges. Infrastructure runs on Cloudflare Workers edge nodes backed by isolated Turso instances for every account.
A PayPal account is mandatory because identity verification and billing depend on it. Self-hosting is not supported. Testing runs free for 90 days, after which pricing is $2.99 monthly, with full JSON export available whenever needed.
What it helps with
- recall previous architectural decisions across fresh conversations
- search remembered facts using varied semantic phrasing and synonyms
- filter stored notes using natural temporal expressions
- retain personal preferences and context across multiple AI clients
Example prompts for the agent
- What library did we decide to use for background jobs last week?
- Check our stored notes for the API endpoint conventions we agreed on.
- Export all my stored memories as a JSON file.
