## Components
### Tools
The server implements multiple tools to interact with Obsidian:
- list_files_in_vault: Lists all files and directories in the root directory of your Obsidian vault
- list_files_in_dir: Lists all files and directories in a specific Obsidian directory
- get_file_contents: Return the content of a single file in your vault.
- search: Search for documents matching a specified text query across all files in the vault
- patch_content: Insert content into an existing note relative to a heading, block reference, or frontmatter field.
- append_content: Append content to a new or existing file in the vault.
- delete_file: Delete a file or directory from your vault.
### Example prompts
Its good to first instruct Claude to use Obsidian. Then it will always call the tool.
The use prompts like this:
- Get the contents of the last architecture call note and summarize them
- Search for all files where Azure CosmosDb is mentioned and quickly explain to me the context in which it is mentioned
- Summarize the last meeting notes and put them into a new note 'summary meeting.md'. Add an introduction so that I can send it via email.
## Requirements
- Python >= 3.11
- `mcp` Python SDK `>=1.1.0,<2.0.0` (pinned in `pyproject.toml`). `mcp-obsidian` currently registers its tool handlers via the `mcp` 1.x low-level `Server` API (`@app.list_tools()` / `@app.call_tool()`), which was removed in `mcp` 2.0. Installing with an unconstrained `mcp>=2.0` will crash at import with `AttributeError: 'Server' object has no attribute 'list_tools'`.
## Configuration
### Obsidian REST API Key
There are two ways to configure the environment with the Obsidian REST API Key.
1. Add to server config (preferred)
```json
{
"mcp-obsidian": {
"command": "uvx",
"args": [
"mcp-obsidian"
],
"env": {
"OBSIDIAN_API_KEY": "<your_api_key_here>",
"OBSIDIAN_HOST": "<your_obsidian_host>",
"OBSIDIAN_PORT": "<your_obsidian_port>"
}
}
}
```
Sometimes Claude has issues detecting the location of uv / uvx. You can use `which uvx` to find and paste the full path in above config in such cases.
2. Create a `.env` file in the working directory with the following required variables:
```
OBSIDIAN_API_KEY=your_api_key_here
OBSIDIAN_HOST=your_obsidian_host
OBSIDIAN_PORT=your_obsidian_port
```
Note:
- You can find the API key in the Obsidian plugin config
- Default port is 27124 if not specified
- Default host is 127.0.0.1 if not specified
## Quickstart
### Install
#### Obsidian REST API
You need the Obsidian REST API community plugin running: https://github.com/coddingtonbear/obsidian-local-rest-api
Install and enable it in the settings and copy the api key.
#### Claude Desktop
On MacOS: `~/Library/Application\ Support/Claude/claude_desktop_config.json`
On Windows: `%APPDATA%/Claude/claude_desktop_config.json`

}
}
}
}
```
</details>
## Docker
You can run the server in a container instead of installing `uv`/Python locally.
1. Copy `.env.example` to `.env` and fill in your Obsidian REST API key:
```bash
cp .env.example .env
```
By default `OBSIDIAN_HOST` is set to `host.docker.internal`, which resolves to
your host machine from inside the container (works on Linux, Mac and Windows).
2. Build the image:
```bash
docker compose build
```
3. Point your MCP client at the container. Since MCP speaks JSON-RPC over
stdio, the client must run it with stdin attached and no pseudo-TTY — use
`docker compose run --rm -T`, not `docker compose up`:
```json
{
"mcpServers": {
"mcp-obsidian": {
"command": "docker",
"args": [
"compose",
"-f",
"<dir_to>/mcp-obsidian/docker-compose.yml",
"run",
"--rm",
"-T",
"mcp-obsidian"
]
}
}
}
```
You can also run it manually to sanity-check the container starts:
```bash
docker compose run --rm -T mcp-obsidian
```
(it will sit waiting for a JSON-RPC message on stdin; Ctrl+C to exit)
## Development
### Building
To prepare the package for distribution:
1. Sync dependencies and update lockfile:
```bash
uv sync
```
### Debugging
Since MCP servers run over stdio, debugging can be challenging. For the best debugging
experience, we strongly recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector).
You can launch the MCP Inspector via [`npm`](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) with this command:
```bash
npx @modelcontextprotocol/inspector uv --directory /path/to/mcp-obsidian run mcp-obsidian
```
Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.
You can also watch the server logs with this command:
```bash
tail -n 20 -f ~/Library/Logs/Claude/mcp-server-mcp-obsidian.log
```
