Long-term memory for AI assistants: permanent, portable across clients, searchable and exportable.

Overview

AI-generated overview

Amber is a hosted long-term memory service that lets an AI assistant save, search and export facts about you across conversations and clients.

What you can do
  • Save memories from normal conversation, chunked into atomic facts with topics and dates
  • Search memories semantically, by keyword and by natural-language time ranges
  • Manage the memory store and account, including export and deletion
  • Send feedback or notifications to the developer
When to use it
Worth adding if you want an assistant to carry preferences, decisions and project context between sessions and across different MCP clients, and you are willing to keep its tools always on and add a custom instruction so it stores memories without being asked.
Requirements
A remote Streamable HTTP endpoint with OAuth 2.1 sign-in; no local package. A PayPal account for billing after the 90-day trial. Two client-side settings: a custom instruction telling the assistant to save memories unprompted, and Amber's tools set to always available.
Before you install
Memory text is sent to a third-party embedding endpoint, and the service is managed only, with no self-hosting. Paid subscription of $2.99/month after the trial, billed through PayPal. The assistant writes, searches and can delete stored personal data, and the README recommends letting it save memories without asking, so review what gets stored and export or delete data as needed.

Installation

In SourceWeft

  1. Open Amber in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.ambermem%2Famber/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

  "mcpServers": {
    "amber": {
      "type": "http",
      "url": "https://mcp.ambermem.com/"

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 - once it is connected and the two required settings below are on.

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

Quick Install

One command. Works with any MCP-compatible client.

Claude Code / Claude Desktop

bash
claude mcp add --transport http --scope user amber https://mcp.ambermem.com

Cursor

Add to ~/.cursor/mcp.json (or %USERPROFILE%\.cursor\mcp.json on Windows):

json
{  "mcpServers": {    "amber": {      "url": "https://mcp.ambermem.com"    }  }}

ChatGPT

Settings → Connectors → Create → URL: https://mcp.ambermem.com

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

json
{  "mcpServers": {    "amber": {      "serverUrl": "https://mcp.ambermem.com"    }  }}

VS Code (GitHub Copilot)

Add to .vscode/mcp.json:

json
{  "servers": {    "amber": {      "type": "http",      "url": "https://mcp.ambermem.com"    }  }}

Any MCP client

URL: https://mcp.ambermem.com | Transport: Streamable HTTP | Auth: OAuth 2.1 (auto-discovered)

Required: two settings

Adding the URL is not enough on its own. Without these two settings, most assistants use Amber only when you explicitly say "remember this", and their built-in memory quietly takes everything else, so Amber stays nearly empty.

  1. Add this to your AI's custom instructions / personal preferences (Claude personal preferences, ChatGPT custom instructions, Cursor rules, etc.):

    Whenever something worth remembering comes up - a life event, a decision, a preference, something I learned or realized, or anything about who I am - save it to Amber (my memory) without asking. Treat normal conversation as a source of memories, not only when I say "remember this".

  2. Keep Amber's tools always available. In your client's tool or MCP settings, set Amber to "always on" rather than on-demand, so your AI can reach it the instant a memory comes up.

How It Works

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

Two settings, once. No tagging. No manual organization.

What Makes Amber Different

FeatureBasic memory serversAmber
StorageOne embedding per memoryMultiple semantic variants per fact
SearchSingle vector lookupHybrid: vector + keyword + RRF fusion
QueriesExact match onlyMany phrasings per fact, matched semantically
InputStored as-isChunked into atomic facts, each independently searchable
TopicsManual tags or noneAuto-grouped, matched semantically at search time
PrivacyVaries by serverNo generative model reads your memories
TimeNo temporal awarenessNatural language time parsing ("last week", "3 days ago")

Technical Details

  • 29 MCP tools (14 memory, 13 account, 2 feedback/notification)
  • Hybrid retrieval pipeline: vector search + full-text search + Reciprocal Rank Fusion
  • Multi-variant embeddings: every fact is stored with several paraphrases (at least 5; a store with fewer is rejected), which is the main thing that makes it findable later
  • No generative model reads your memories: your assistant does the chunking, the topics and the phrasings. Memory text is sent only to an embedding endpoint (a vector model, not a chat model), so no chat model is ever shown what you store
  • Atomic facts: a conversation becomes individually searchable facts rather than one blob, each with its own subjects, topics and dates
  • Temporal search: "what did I say last week?" resolves to a real date range rather than a keyword match
  • Automatic topic grouping: memories are grouped by topic, and a search for "work" also finds "career" and "job"
  • Async processing: storage completes in the background, never blocking your conversation

Pricing

  • 90-day free trial - no charge, cancel anytime
  • $2.99/month after trial, via PayPal
  • Cancel instantly - ask your AI to cancel, or cancel through PayPal directly
  • No lock-in - export all your data as JSON anytime

Privacy

  • No email collected
  • No marketing, no spam
  • Data isolated per user (separate database)
  • PayPal handles all payment info
  • Full export + account deletion available
  • GDPR compliant (data minimization by design)

Architecture

Amber runs on Cloudflare Workers (zero cold starts, global edge deployment) with Turso databases (one per user, full isolation). Your assistant does the chunking, the topics and the phrasings, so no generative model is ever shown what you store; memory text is sent only to OpenAI's embedding endpoint.

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.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
