Streamient

Open source memory infrastructure for teams.
Turn scattered company knowledge into AI-ready context.

Intro video

Stop reset loops. Give every AI tool trusted memory your team can inspect, control, and reuse.

Streamient is an open-source memory layer for AI-native teams and MCP-compatible tools. Store notes, memories, URLs, and relationships in one place, then let assistants retrieve the right context across sessions, projects, and clients.

Why Streamient?

AI tools are great at reasoning and terrible at remembering.

Streamient gives you a shared, searchable, editable memory layer that sits between your team and your AI tools:

• Persistent context — keep preferences, decisions, docs, and bookmarks across sessions
• Works across tools — use the same memory store with Claude Desktop, Cursor, and other MCP clients
• Open and inspectable — your memory is not trapped in a black box
• Built for teams — organize knowledge by project, connect related items, and make it reusable

What’s included

• Notes — rich-text documents with full-text and semantic search
• Memories — short-form context for preferences, decisions, and learnings
• URLs — saved pages with extracted content and optional full-site crawling
• Knowledge Graph — manual, tag-based, and semantic links between items
• AI Chat — search and manage knowledge with natural language
• MCP Server — 44 tools for notes, memories, URLs, projects, graph, and search
• CLI — composable terminal access to the complete MCP tool catalog
• Browser Extension — save notes and URLs from anywhere
• Obsidian Sync — scoped two-way sync for multiple projects and accounts in one vault
• Bidirectional Git Sync — sync project knowledge to and from Git repositories

How it works

1. Capture knowledge — add notes, store memories, save URLs, or import documents
2. Connect your tools — plug Streamient into Claude Desktop, Cursor, or another MCP client
3. Retrieve the right context — your assistant searches and reuses what matters, instead of starting from zero every time

Cloud or self-hosted

Streamient Cloud and the self-hosted edition share the same product features. The difference is who runs the infrastructure.

	Cloud	Self-Hosted
Features	All	All
Hosting	Managed by us	You manage
Updates	Automatic	Manual
Backups	Included	You configure
Pricing	Subscription	Free (open source)

Quick start

Streamient Cloud

1. Sign up at app.streamient.com
2. Create your first project
3. Generate a personal access token in Settings → Tokens
4. Add Streamient to your AI tool

Example Claude Desktop config on macOS:

{
    "mcpServers": {
        "streamient": {
            "command": "npx",
            "args": ["-y", "mcp-remote", "https://mcp.streamient.com/mcp"],
            "env": {
                "ACCESS-TOKEN": "your-access-token"
            }
        }
    }
}

Self-hosted

Production with Docker Compose

Requirements:

• Node.js >= 24
• Docker & Docker Compose
• pnpm 10+ (for local development)
• MongoDB 6+
• Memcached 1.6+
• Typesense 31+

Grab the production Compose file and pass configuration as shell environment variables:

curl -O https://raw.githubusercontent.com/streamient/streamient/main/compose.prod.yml

APP_URL=https://your-instance.com \
SESSION_SECRET=your-session-secret \
JWT_SECRET=your-jwt-secret \
TYPESENSE_API_KEY=your-typesense-key \
SMTP_HOST=smtp.example.com \
SMTP_USER=you@example.com \
SMTP_PASS=your-smtp-password \
SMTP_FROM=noreply@example.com \
GOOGLE_API_KEY=your-google-api-key \
docker compose -f compose.prod.yml up -d

For multiple outbound SMTP servers, set SMTP_SERVERS to a JSON array of server objects. Streamient sends through them round-robin.

Example:

SMTP_SERVERS='[
	{
		"name": "smtp-1",
		"host": "smtp1.example.com",
		"port": 587,
		"secure": false,
		"user": "smtp-user-1",
		"pass": "smtp-pass-1",
		"from": "server@streamient.com"
	},
	{
		"name": "smtp-2",
		"host": "smtp2.example.com",
		"port": 465,
		"secure": true,
		"user": "smtp-user-2",
		"pass": "smtp-pass-2",
		"from": "server@streamient.com"
	}
]'

In Docker Compose YAML, quote it as a single JSON string:

environment:
    SMTP_FROM: server@streamient.com
    SMTP_SERVERS: >-
        [{"name":"smtp-1","host":"smtp1.example.com","port":587,"secure":false,"user":"smtp-user-1","pass":"smtp-pass-1","from":"server@streamient.com"},{"name":"smtp-2","host":"smtp2.example.com","port":465,"secure":true,"user":"smtp-user-2","pass":"smtp-pass-2","from":"server@streamient.com"}]

Only host is required per server. port defaults to 587, secure defaults to true only for port 465, and from falls back to SMTP_FROM.

No .env file is required for this setup.

Default service ports:

Service	Port
App	3000
WebSocket	3001
MCP Server	3002
MongoDB	27017
Memcached	11211
Typesense	8108

Local development

For repository development, make sure MongoDB, Memcached, and Typesense are available, then run:

git clone https://github.com/streamient/streamient.git
cd streamient
pnpm install
pnpm dev

Useful scripts:

• pnpm dev — run the app with auto-reload
• pnpm build — build frontend assets
• pnpm test — run the test suite
• pnpm test:mcp — run MCP-specific tests
• pnpm docs:dev — run the docs site locally

MCP server

Streamient includes a built-in Model Context Protocol server with:

• 44 tools across notes, memories, URLs, projects, graph, search, and AI chat
• Shared memory across tools so Claude Desktop, Cursor, and others pull from the same context
• Three transports — stdio, SSE, and Streamable HTTP
• Token-based auth via Authorization: Bearer, access-token, or stdio env vars
• Automatic default project selection so tools work without extra setup

Self-hosted example:

env 'ACCESS-TOKEN'=your-access-token API_BASE_URL=https://your-instance.com node apps/mcp/server.js

CLI

The @streamient/cli package exposes Streamient's complete MCP tool catalog to people, shell scripts, CI jobs, and coding agents. It supports multiple account aliases and discovers command schemas from the connected server.

pnpm add --global @streamient/cli
set -gx STREAMIENT_CLI_ACCESS_TOKEN 'your-personal-access-token'
streamient-cli doctor

Obsidian Sync

Streamient Sync keeps one Obsidian vault synchronized with multiple Streamient projects and OAuth accounts. Each project has its own managed folder and optional extra-vault scope, with first-sync review, sequential processing, cooperative abort/resume, and newest-wins conflict recovery. Notes, Memories, and saved URLs round-trip as Markdown; Canvas, Bases, documents, and attachments are also mirrored.
