Paste into the AI you're chatting with — it will figure out the rest

Please install the `hebbian-vault` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Install Python 3.10+** — Python 3.10 or newer is required to run hebbian-vault.
- **Install hebbian-vault** — Install the MCP server package from PyPI. Run: `pip install hebbian-vault`
- **Have an Obsidian vault available** — You need a local Obsidian vault path to point the server at. Wikilinks are recommended for graph features.

Canonical MCP server config (stdio transport):
- command: `hebbian-vault`
- args: ["--vault","<path-to-your-obsidian-vault>"]
- optional environment variables:
  - `HEBBIAN_VAULT_LICENSE`: Pro license JWT for enabling Pro features such as inline tracking. Not required for standard usage. (example: `<your-license-jwt>`)

Note: Default transport is stdio. The server also supports HTTP via --transport streamable-http and --port <port>, but the README does not provide a canonical URL shape for client configuration, so the portable default stdio configuration is preferred. Optional CLI flags include --inline-tracking for Pro users and --license-key <your-license-jwt> as an alternative to the HEBBIAN_VAULT_LICENSE environment variable.

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.
