Memory Custom : PouchDB
[](https://smithery.ai/server/@bneil/mcp-memory-pouchdb)
This project adds new features to the Memory server offered by the MCP team. It allows for the creation and management of a knowledge graph that captures interactions via a language model (LLM).
This repo was forked from [https://github.com/BRO3886/mcp-memory-custom](https://github.com/BRO3886/mcp-memory-custom) which was a great starting point, thanks again for fixing timestamps. This repo's goal was more to fix the issue with an ever increasing json file for context.
New Features
1. PouchDB Integration
- The server now uses PouchDB for robust document-based storage
- **Why?**: Better data consistency, built-in versioning, and improved performance for large datasets
- Maintains file backup for compatibility
2. Custom Memory Paths
- Users can now specify different memory file paths for various projects
- **Why?**: This feature enhances organization and management of memory data, allowing for project-specific memory storage
3. Timestamping
- The server now generates timestamps for interactions
- **Why?**: Timestamps enable tracking of when each memory was created or modified, providing better context and history for the stored data
Getting Started
Prerequisites
- Node.js (version 16 or higher)
- PouchDB (automatically installed as a dependency)
Installing via Smithery
To install Knowledge Graph Memory Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@bneil/mcp-memory-pouchdb):
Installation
- Clone the repository: ```bash git clone git@github.com:bneil/mcp-memory-pouchdb.git cd mcp-memory-pouchdb ```
- Install the dependencies: ```bash npm install ```
Configuration
The server requires two environment variables to be set:
- `MEMORY_FILE_PATH`: The absolute path where the memory backup file will be stored
- `POUCHDB_PATH`: The absolute path where the PouchDB database will be stored
Example configuration in your `claude_desktop_config.json` / `.cursor/mcp.json`:
The server will fail to start if either environment variable is not set.
Optional environment variables:
- `POUCHDB_OPTIONS`: JSON string of additional PouchDB configuration options
- `DISABLE_MEMORY_FILE`: Set to "true" to disable saving to memory.json file (only use PouchDB for storage)
Running the Server
Updating the mcp server json file
Add this to your `claude_desktop_config.json` / `.cursor/mcp.json` file:

Running the Server Locally
To start the Knowledge Graph Memory Server, run:
The server will listen for requests via standard input/output.
API Endpoints

- **Get Current Time**
- **Set Memory File Path**
- **Create Entities**
- **Create Relations**
- **Add Observations**
- **Delete Entities**
- **Delete Observations**
- **Delete Relations**
- **Read Graph**
