CortexGraph is an MCP server that provides human-like memory dynamics for AI assistants, allowing them to remember and forget information naturally over time. It mimics human memory by reinforcing frequently referenced memories and fading unused ones.
From the registry: Temporal memory for AI with decay and reinforcement. Two-layer storage (JSONL + Markdown).
Install & configure
Prerequisites
- requiredInstall cortexgraphInstall via uv tool (recommended)
https://pypi.org/project/cortexgraph/$ uv tool install cortexgraph
Install in your client
Paste into the AI you're chatting with — it will figure out the rest
Please install the `mnemex` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Install cortexgraph** — Install via uv tool (recommended) Run: `uv tool install cortexgraph` (https://pypi.org/project/cortexgraph/)
Canonical MCP server config (stdio transport):
- command: `cortexgraph`
- args: []
- optional environment variables:
- `CORTEXGRAPH_STORAGE_PATH`: Path to JSONL memory storage (example: `~/.config/cortexgraph/jsonl`)
- `CORTEXGRAPH_DECAY_MODEL`: Decay model: power_law, exponential, or two_component (example: `power_law`)
- `LTM_VAULT_PATH`: Obsidian vault path for long-term memory (example: `~/Documents/Obsidian/Vault`)
Note: Originally 'mnemex', renamed to CortexGraph under Prefrontal Systems. Temporal decay memory with Ebbinghaus forgetting curve. Research POC.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Note: Originally 'mnemex', renamed to CortexGraph under Prefrontal Systems. Temporal decay memory with Ebbinghaus forgetting curve.
