+
+OpenViking: Context Database for AI Agents — semantic search, memory management, resource ingestion, and session management over MCP.
+
+Source: [`volcengine/OpenViking`](https://github.com/volcengine/OpenViking)
+
+OpenViking has a **built-in HTTP MCP endpoint** at `/mcp` on port 1933 — no mcp-proxy needed.
+
+## Prerequisites
+
+A valid `ov.conf` configuration file is required. Generate one:
+
+```bash
+docker run --rm -it \
+  -v ~/.openviking:/app/.openviking \
+  forgejo.corentic.eu/corentic/mcp-fleet-openviking:latest \
+  openviking-server init
+```
+
+Validate setup:
+```bash
+docker run --rm -it \
+  -v ~/.openviking:/app/.openviking \
+  forgejo.corentic.eu/corentic/mcp-fleet-openviking:latest \
+  openviking-server doctor
+```
+
+## Environment Variables
+
+| Variable | Required | Description |
+|----------|----------|-------------|
+| `OPENVIKING_CONFIG_FILE` | No | Path to ov.conf inside container (default: `/app/.openviking/ov.conf`) |
+| `OPENVIKING_CONF_CONTENT` | No | Inline config content (alternative to volume mount) |
+| `OPENVIKING_SERVER_HOST` | No | Server bind address (default: `0.0.0.0`) |
+| `OPENVIKING_PUBLIC_BASE_URL` | No | Public URL for file upload signed URLs (needed behind reverse proxy) |
+| `OPENVIKING_WITH_BOT` | No | Set to `0` to disable VikingBot |
+
+## Usage
+
+```bash
+docker run -d \
+  --name openviking-mcp \
+  -p 1933:1933 \
+  -v ~/.openviking:/app/.openviking \
+  --restart unless-stopped \
+  forgejo.corentic.eu/corentic/mcp-fleet-openviking:latest
+```
+
+MCP endpoint: `http://host:1933/mcp`
+
+## Client Configuration
+
+Connect from any MCP client:
+
+```json
+{
+  "mcpServers": {
+    "openviking": {
+      "url": "http://host:1933/mcp"
+    }
