M365 Copilot Chat Automation

Interact with Microsoft 365 Copilot Chat through Playwright MCP browser automation.

Prerequisites

• Playwright MCP Bridge browser extension installed in Edge
• PLAYWRIGHT_MCP_EXTENSION_TOKEN configured in MCP server env
• MCP server running with --extension flag
• User already signed into M365 in Edge

Core Workflow

1. Open M365 Chat

browser_navigate to https://m365.cloud.microsoft/chat

Wait for the page to load. Take a snapshot to verify the "Message Copilot" input is visible.

2. Select an Agent

Available agents appear in the left sidebar under "Agents":

Agent	Purpose
Cowork	Daily productivity — emails, calendar, standups, inbox triage
Researcher	Deep research and analysis across web and work data
Analyst	Data analysis, charts, spreadsheet insights
Sales	CRM, pipeline, customer intelligence

Click the agent name in the sidebar. Wait for the agent's UI to load (header changes to agent name).

3. Send a Prompt

1. Snapshot the page to get the current input field ref
2. Click the input field (labeled "Message Copilot" or "How can I help you today?")
3. Fill the input with your prompt text
4. Press Enter to send

4. Wait and Read Response

Copilot responses take 20-50 seconds to complete. After sending:

1. Wait at least 25 seconds before taking a snapshot
2. Take a snapshot and check if the response is fully rendered
3. If the response shows "Generating..." or a spinner, wait another 15 seconds and snapshot again
4. The response appears below the sent message in the chat thread

5. Follow-up Messages

For subsequent messages in the same conversation:

1. Snapshot the page to get the LATEST input field ref (it changes between interactions)
2. Click the new input field
3. Fill and Press Enter as before

Timing Guidelines

Action	Wait Time
Page load after navigate	5 seconds
Agent selection	3 seconds
Simple response (email summary)	25 seconds
Complex response (multi-step task)	45 seconds
Follow-up in same conversation	25 seconds

Example Prompts by Agent

Cowork

• "Summarize my unread emails from today"
• "What meetings do I have for the rest of this week?"
• "Draft a 5-sentence standup update based on my recent activity"
• "Organize my inbox by priority"

Researcher

• "Research the latest trends in AI agent frameworks"
• "Find information about [topic] from my work documents"

Analyst

• "Analyze the data in [spreadsheet name]"
• "Create a chart from my recent sales numbers"

Important Notes

• Always use --extension mode to reuse the logged-in browser session
• The chat input ref changes between messages — always snapshot before filling
• M365 uses Content Security Policy (CSP) restrictions; the playwright-config.json includes Edge flags to bypass these
• If a response shows "Error" status for some API calls, Copilot may still produce useful output by retrying with different approaches
