KnowledgeBaseServer

# MCP KnowledgeBase Server [](https://hub.docker.com/r/mbcrawfo/knowledge-base-server)  A [Model Context Protocol](https://modelcontextprotocol.io/) (MCP) server that allows LLMS to store memories during a conversation and search them later. Memories are stored in a [SQLite](https://www.sqlite.org) database, and its full text search features power the memory search. ## Usage Two environment variables control the location and filename of the database. `DATABASE_NAME`: Use the default location, but a custom db filename. For example, `my_custom_db.sqlite`. `DATABASE_PATH`: Specify the fully path to the db file (ignores `DATABASE_NAME`). For example, `/Users/your_name/.db/my_db.sqlite`. ### Docker When using docker you must create a persistent volume to store the database (advanced users can mount a folder from their file system, if desired). Run `docker volume create knowledgebase` to set it up, then configure the server in your `claude_desktop_config.json` as below. If you want to use a custom database file with docker you must use `DATABASE_PATH` and pass it to the docker command using the `--env` arg. For example (place these strings in the `args` array of the config, before the image name), `"--env", "DATABASE_PATH=/db/my_db.sqlite"`. ```json { "mcpServers": { "knowledgebase": { "command": "docker", "args": [ "run", "--interactive", "--rm", "--volume", "knowledgebase:/db", "mbcrawfo/knowledge-base-server" ] } } } ``` ### Run locally with dotnet cli 1. You will need the [.Net 9 SDK](https://dotnet.microsoft.com/en-us/download/dotnet/9.0). 2. Clone this repository. 3. Navigate to the repo in your terminal and run `dotnet build`. 4. Add the config below to `claude_desktop_config.json` (if you get errors, try specifying the full path to the dotnet cli). When running locally the default database location is in your Application Data directory. ```json { "mcpServers": { "knowledgebase": { "command": "dotnet", "args": [ "run", "--project", "/full/path/to/repo/src/KnowledgeBaseServer/KnowledgeBaseServer.csproj", "--no-restore", "--no-build" ] } } } ``` ## Prompts The server includes a "General Memory Usage" prompt to tell the LLM how to use memory. However you may wish to use a custom prompt to be more specific to your usage. ## Development You can use the app with the `--init-db` parameter to create or upgrade databases for testing. From the KnowledgeBaseServer project directory, run `dotnet run -- --init-db /path/to/db.sqlite`.
