学校通讯平台MCP服务器

Wilma MCP Server

An MCP (Model Context Protocol) server for Wilma - the Finnish school communication platform by Visma. This allows Claude and other MCP-compatible AI assistants to interact with school data including schedules, messages, and more.

Features

• Schedule - View daily or weekly timetables with subjects, times, and teachers
• Messages - Read inbox messages with read/unread status, view full content, mark as read
• Recipients - List available message recipients (teachers, staff)
• Send Messages - Compose and send messages to teachers

Prerequisites

• Python 3.11 or higher
• A Wilma account (student, guardian, or teacher)
• Your school's Wilma URL (e.g., https://yourschool.inschool.fi)

Installation

# Clone the repository
git clone https://github.com/jessemc98/wilma-mcp.git
cd wilma-mcp

# Create virtual environment
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install the package
pip install -e .

Configuration

Create a .env file with your Wilma credentials:

cp .env.example .env

Edit .env:

WILMA_BASE_URL=https://yourschool.inschool.fi
WILMA_USERNAME=your_username
WILMA_PASSWORD=your_password

Security Note: Never commit your .env file to version control.

Usage with OpenClaw

If you use OpenClaw, this project includes a SKILL.md that automatically teaches your agent how to use the Wilma MCP tools.

1. Complete the Installation and Configuration steps above.
2. Add the MCP server to your Claude Code settings (~/.claude.json or project .mcp.json):

{
  "mcpServers": {
    "wilma": {
      "command": "/path/to/wilma-mcp/venv/bin/python",
      "args": ["-m", "wilma_mcp.server"],
      "cwd": "/path/to/wilma-mcp"
    }
  }
}

3. Place or symlink the SKILL.md into your OpenClaw skills directory so the agent can discover it.

Usage with Claude Desktop

Add the server to your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "wilma": {
      "command": "/path/to/wilma-mcp/venv/bin/python",
      "args": ["-m", "wilma_mcp.server"],
      "cwd": "/path/to/wilma-mcp"
    }
  }
}

Restart Claude Desktop after updating the configuration.

Available Tools

get_schedule

Get the school schedule for a specific date.

Parameters:

• date_str (optional): Date to get schedule for. Defaults to "today".
  • Supports: "today", "tomorrow", "yesterday"
  • Weekday names: "monday", "tuesday", etc. (English or Finnish)
  • Date formats: "2024-03-15", "15.3.2024"

Example: "What's my schedule for Monday?"

get_week_schedule

Get the schedule for a full week.

Parameters:

• start_date (optional): Start date of the week. Defaults to today.

Example: "Show me next week's schedule"

get_messages

Get list of messages from inbox. Each message shows a read/unread indicator (📖 read, 📬 unread).

Parameters:

• folder (optional): Folder name - "inbox", "sent", "archive", or "drafts". Defaults to "inbox".
• limit (optional): Maximum messages to return. Defaults to 20.

For "sent" and "drafts" the listing shows the recipient ("To:") rather than the sender.

Example: "Check my messages" / "Show my sent messages"

get_message

Read a specific message with full content. Note: viewing a message automatically marks it as read on the Wilma server.

Parameters:

• message_id: The ID of the message to read.

Example: "Read message 12345"

set_message_read

Explicitly mark a message as read. Useful for marking messages as read without reading their full content. Wilma does not support marking messages as unread — this is a platform limitation.

Parameters:

• message_id: The ID of the message to mark as read.

Example: "Mark message 12345 as read"

get_recipients

Get list of available message recipients (teachers, staff, guardians).

Parameters:

• query (optional): Case-insensitive name filter (e.g. a teacher's surname). Handy because a school's full recipient list can be long.

Each returned recipient has an id string (e.g. r_guardian=11876_2893&n_class=33) that you can pass straight to send_message.

Example: "Who can I send messages to?" / "Find the recipient for Mr. Smith"

send_message

Send a new message to any recipient (teacher, staff member, or guardian).

Parameters:

• recipient: Who to send to — either a person's name (e.g. "Galiana Fatima", resolved automatically against the recipient list) or a recipient id from get_recipients (e.g. "r_guardian=11876_2893&n_class=33"). To address several people, join their ids with &.
• subject: Message subject
• body: Message body/content

If a name matches more than one person, the tool returns the list of matches so you can pick a specific id (it will not guess).

Example: "Send a message to Mr. Smith about homework"

To reply to an existing message, use reply_to_message instead — it resolves the recipient automatically from the original message.

reply_to_message

Reply to an existing message. This is the preferred way to reply since it handles recipient resolution automatically via Wilma's reply form, without needing to look up recipient IDs.

Parameters:

• message_id: ID of the message to reply to (from get_messages)
• body: Reply message body/content

Example: "Reply to message 12345 saying I'll attend"

Example Conversations

Once configured, you can ask Claude:

• "What's my schedule today?"
• "Do I have any classes on Friday?"
• "Show me my unread messages"
• "Read the message from my teacher"
• "What time does school start tomorrow?"

Technical Notes

• Wilma has no official public API. This server reverse-engineers the web interface.
• Authentication uses session cookies obtained via the login flow.
• Schedule data is extracted from embedded JavaScript in the schedule page.
• Message lists use per-folder JSON endpoints (/messages/list for the inbox, /messages/list/outbox for sent, /messages/list/archive, /messages/list/drafts); individual messages require HTML parsing.
• Read/unread tracking: Wilma's JSON API includes a Status field per message — truthy means unread, falsy/absent means read. Viewing a message (GET request) marks it as read server-side. There is no API to mark a message as unread.
• Sending messages: Wilma does not expose recipients as <option> elements. The recipient picker (/messages/recipients) embeds each reachable person as a .recipient-block whose data-source link encodes a selector of the form r_<type>=<id> (e.g. r_guardian, r_personnel, r_ownteachers). To compose, the server GETs /messages/compose?<selector> (which returns the form with a fresh formkey and the recipient pre-added as a hidden r_<type> input), fills the Subject and BodyText fields, and POSTs with the addsavebtn "send" button. This is why new messages now work, not only replies.
• The server may need updates if Wilma's web interface changes.
