MCP server to interact with Obsidian via the Local REST API community plugin.
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 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)
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:
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

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:
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).
