MCP 服务器

Amber

Gives your AI persistent memory across conversations. Stores facts automatically, finds them by meaning using hybrid search with query expansion, and organizes everything into topics without manual tagging.

README

Amber

Long-term memory for AI assistants.

Amber is an MCP server that gives any AI assistant persistent, searchable memory across conversations. Your AI remembers preferences, decisions, project context, and personal details - without you doing anything special.

Just talk normally. Amber stores what matters and finds it when relevant.

Quick Install

One command. Works with any MCP-compatible client.

How It Works

You talk to your AI normally. Amber stores important facts in the background.
Next conversation, your AI searches Amber automatically when context would help.
Memory improves over time. The more you use it, the better it gets.

No configuration. No tagging. No manual organization.

What Makes Amber Different

Feature	Basic memory servers	Amber
Storage	One embedding per memory	Multiple semantic variants per fact
Search	Single vector lookup	Hybrid: vector + keyword + RRF fusion
Queries	Exact match only	Auto-expanded (synonyms, paraphrases)
Input	Stored as-is	LLM-chunked into atomic facts
Topics	Manual tags or none	Auto-categorized by LLM
Time	No temporal awareness	Natural language time parsing ("last week", "3 days ago")

Technical Details

18 MCP tools (9 memory, 7 account, 2 feedback)
Hybrid retrieval pipeline: vector search + full-text search + Reciprocal Rank Fusion
LLM-powered chunking: text → atomic facts, each independently searchable
Multi-variant embeddings: each fact stored with ~4 paraphrases for higher recall
Query expansion: searches are auto-rephrased to find semantically related memories
Automatic topic categorization: memories grouped by LLM-generated topics
Temporal parsing: "what did I say last week?" just works
Async processing: storage completes in 10-30s background, never blocks your conversation

Architecture

Amber runs on Cloudflare Workers (zero cold starts, global edge deployment) with Turso databases (one per user, full isolation). LLM processing uses Gemini Flash for chunking/expansion and OpenAI for embeddings.

FAQ

Will it slow my AI down? No. Storage is async (background). Search adds <1 second.

What if Amber shuts down? Export all your data as JSON anytime. Your data is always yours.

Do I need a PayPal account? Currently yes. PayPal handles both identity and billing. More login options coming soon.

Is my data safe? Each user gets a completely isolated database. No data is shared between users. Amber has no access to your PayPal payment details.

Can I self-host? Not currently. Amber is a managed service. We handle the infrastructure, scaling, and LLM costs so you don't have to.
