# Streamient > Open source memory infrastructure for teams. > Turn scattered company knowledge into AI-ready context. ## Intro video [](http://www.youtube.com/watch?v=DnNchFuE1Do) 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. [Website](https://streamient.com) · [Cloud](https://app.streamient.com) · [Docs](https://docs.streamient.com) · [Self-Hosted Guide](https://docs.streamient.com/selfhosted/) · [MCP Docs](https://docs.streamient.com/mcp/) · [API Reference](https://docs.streamient.com/api/)  ## 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 - **Browser Extension** — save notes and URLs from anywhere - **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](https://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: ```json { "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+ - Redis 6+ - Typesense 31+ Grab the production Compose file and pass configuration as shell environment variables: ```bash 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: ```bash 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: ```yaml 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` | | Redis | `6379` | | Typesense | `8108` | ### Local development For repository development, make sure MongoDB, Redis, and Typesense are available, then run: ```bash 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](https://modelcontextprotocol.io/) 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: ```bash env 'ACCESS-TOKEN'=your-access-token API_BASE_URL=https://your-instance.com node apps/mcp/server.js ``` ## Architecture at a glance - **Backend** — Node.js + Express - **Database** — MongoDB - **Search** — Typesense for full-text and semantic retrieval - **Cache / real-time** — Redis + Socket.IO - **Frontend** — Pug templates + vanilla JavaScript - **MCP app** — `apps/mcp/` for agent integrations ## Documentation - [Guide](https://docs.streamient.com/guide/) - [Self-Hosted](https://docs.streamient.com/selfhosted/) - [MCP Server](https://docs.streamient.com/mcp/) - [API Reference](https://docs.streamient.com/api/) - [Cloud](https://docs.streamient.com/cloud/) ## License Licensed under [AGPL-3.0](LICENSE).
