leafwiki-mcp

An MCP server that lets compatible clients discover, read, organize, revise, favorite, create, edit, and delete content in a LeafWiki instance.

Status

The project is at version 0.1.0 and is under early development. It runs as a synchronous MCP server over stdio. Installation from PyPI is not currently documented or supported; run it from a source checkout.

Related MCP server: mediawiki-mcp-server

Prerequisites

• Python 3.12 or newer

• uv

Installation

Clone the repository over HTTPS:

git clone https://github.com/ipapadop/leafwiki-mcp.git
cd leafwiki-mcp
uv sync

Or clone it over SSH:

git clone git@github.com:ipapadop/leafwiki-mcp.git
cd leafwiki-mcp
uv sync

Configuration

The server accepts command-line options or equivalent environment variables:

Credentials are unnecessary when authentication is disabled. Accounts requiring TOTP are not supported; use a dedicated editor account without TOTP.

The password in the MCP client example below is stored directly in that client's configuration. Protect the configuration as you would any other credential. For an authentication-disabled LeafWiki instance, omit LEAFWIKI_USERNAME and LEAFWIKI_PASSWORD entirely.

Running

uv run leafwiki-mcp

Example MCP client configuration:

{
  "mcpServers": {
    "leafwiki": {
      "command": "uv",
      "args": [
        "--directory",
        "/absolute/path/to/leafwiki-mcp",
        "run",
        "leafwiki-mcp"
      ],
      "env": {
        "LEAFWIKI_URL": "https://wiki.example.com",
        "LEAFWIKI_USERNAME": "mcp-editor",
        "LEAFWIKI_PASSWORD": "replace-me"
      }
    }
  }
}

The server exposes these tools over stdio:

• search_pages: search page text and tags with pagination

• get_page: retrieve Markdown content and metadata by ID or path

• browse_tree: browse the page hierarchy with an optional depth limit

• get_page_links: retrieve backlinks, outgoing links, and broken links

• list_tags: discover tags and their usage counts

• find_pages_by_property: find pages by structured property metadata

• list_page_revisions: list revision history when revisions are enabled

• get_page_revision: retrieve a historical page snapshot when revisions are enabled

• compare_page_revisions: compare two historical snapshots

• get_indexing_status: inspect full-text indexing state

• list_property_keys, find_page_by_title, lookup_path, and suggest_slug: discover page metadata and paths

• move_page, copy_page, ensure_path, convert_page, and pin_page: organize pages

• add_favorite, remove_favorite, and list_favorites: manage personal bookmarks

• append_to_page, update_page_tags, and update_page_properties: make focused page updates

• sort_pages: set the ordering of children under a page

• add_page, edit_page, and delete_page: mutate pages using optimistic concurrency

Tools that select a page accept an ID or slash-separated path and prefer a non-empty ID when both are supplied. Revision tools require revisions to be enabled in LeafWiki. Favorites require an authenticated user when authentication is enabled.

Page edits and deletions use LeafWiki versions for optimistic concurrency. A conflict is returned as an error so callers can re-read the page and retry deliberately. Deletion is non-recursive by default; recursive deletion must be requested explicitly. Creating a page with content, tags, or properties performs a create followed by a versioned update, so creation may succeed even if the follow-up update fails.

Troubleshooting

• Cannot connect: confirm LEAFWIKI_URL includes http:// or https://, points to a running LeafWiki instance, and is reachable from the MCP client process.

• Authentication required: set both LEAFWIKI_USERNAME and LEAFWIKI_PASSWORD, or omit them when LeafWiki reports that authentication is disabled.

• TOTP required: TOTP accounts are unsupported. Use a dedicated editor account without TOTP.

• Revision request fails: confirm revisions are enabled in the LeafWiki instance.

• Update or deletion conflicts: re-read the page to obtain its current version, review the intervening change, and retry deliberately.

Development

The tests use mocked HTTP transports and clients. They do not require a live LeafWiki instance, network access, or real credentials.

This repository does not currently define GitHub Actions workflows, so these local commands are the canonical quality gate.
