The MCP Session Closer is a server designed to manage and close work sessions in Cursor, ensuring that all context files are synchronized, session summaries are updated, and changes are committed to git.

MCP Session Closer

A Model Context Protocol (MCP) server for Cursor that gracefully closes work sessions, syncs context files, updates Agent OS files, and commits changes to git.

Features

  • end_session: Close Cursor sessions with automatic context sync, Notion entry creation, and git commit
  • sync_context_files: Sync context files across claude.md, gemini.md, agents.md, and .cursor/context.md
  • update_session_summary: Update session summaries without closing the session
  • create_notion_entry: Create Notion entries from markdown content (append to page or create in database)
  • Notion Integration: Automatically creates Notion entries via MCP tools (with Python script fallback)

Quick Setup

1. Install Dependencies

npm install

2. Build the Server

npm run build

3. Configure Cursor

Add to your Cursor MCP settings (~/.cursor/mcp.json or %APPDATA%\Cursor\mcp.json on Windows):

{
  "mcpServers": {
    "session-closer": {
      "command": "node",
      "args": [
        "/path/to/mcp-session-closer/dist/index.js"
      ],
      "env": {
        "CURSOR_WORKSPACE": "${workspaceFolder}"
      }
    }
  }
}

Note: Replace /path/to/mcp-session-closer with your actual path. On Windows, use forward slashes or double backslashes.

4. Restart Cursor

Restart Cursor to load the MCP server.

Usage

End Session

In Cursor chat, simply ask:

Close this session and sync everything

Or use the tool directly:

Use end_session with conversationSummary: "Implemented user auth, fixed login bugs"

The server will:

  1. Extract session details (accomplishments, decisions, blockers, next steps)
  2. Update .agent-os/session-summary.md
  3. Create Notion entry via MCP (or fallback to Python script)
  4. Update Agent OS roadmap and decisions (if present)
  5. Sync all context files (claude.md, gemini.md, agents.md, .cursor/context.md)
  6. Commit all changes to git with descriptive message

Sync Context Files Only

Sync context files

Or:

Use sync_context_files

Update Session Summary Only

Use update_session_summary with summary: "Made progress on feature X"

Create Notion Entry from Markdown

Create a Notion entry directly from markdown content. This is useful for adding completion reports, documentation, or any structured content to Notion.

Append to existing page:

Use create_notion_entry with markdownContent: "# My Report\n\nContent here..." and pageId: "your-page-id"

Create new page in database:

Use create_notion_entry with markdownContent: "# My Report\n\nContent here..." and databaseId: "your-database-id"

With custom title and date:

Use create_notion_entry with markdownContent: "# My Report\n\nContent here...", databaseId: "your-database-id", title: "Custom Title", date: "2026-02-08", project: "Development"

Features:

  • Automatically converts markdown to Notion blocks
  • Handles large content by chunking (Notion limit: 100 blocks per request)
  • Extracts title from first H1 if not provided
  • Extracts date from markdown if present
  • Falls back to direct Notion API if MCP tools unavailable

How It Works

Session Closing Flow

When you call end_session, the server automatically:

  1. Gathers Session Info

    • Extracts accomplishments from conversation
    • Identifies decisions made
    • Notes any blockers
    • Lists next steps
    • Tracks changed files

  2. Updates Session Summary

    • Creates/updates .agent-os/session-summary.md
    • Appends session details with timestamp
    • Formats as structured markdown

  3. Updates Agent OS (if present)

    • Marks completed items in .agent-os/product/roadmap.md
    • Adds new decisions to .agent-os/product/decisions.md
    • Maintains proper markdown structure

  4. Syncs Context Files

    • Reads content from all context files
    • Merges and deduplicates content
    • Updates all files with unified context:
      • claude.md
      • gemini.md
      • agents.md
      • .cursor/context.md

  5. Commits to Git

    • Stages all modified files
    • Creates descriptive commit message
    • Commits with timestamp

Configuration

Required Environment Variables

  • CURSOR_WORKSPACE - Set automatically by Cursor to the current workspace folder

Notion Integration

The server can automatically create Notion entries when closing sessions, and you can also create entries manually using the create_notion_entry tool. Configure via environment variables:

Required:

Choose one (for automatic session entries):

  • NOTION_PAGE_ID - Append blocks to existing page (recommended, avoids serialization issues)
  • NOTION_DATABASE_ID - Create new page in database

Optional:

  • NOTION_PROJECT - Default project name for database entries (default: "Development")

Example:

export NOTION_API_TOKEN="ntn_your_token_here"
export NOTION_DATABASE_ID="2ba968fc-73c0-8045-b1c7-c89951ece547"
export NOTION_PROJECT="Development"

How it works:

  1. Primary: Uses Notion MCP tools via Docker (mcp/notion:latest)
  2. Fallback: If MCP fails, falls back to direct Notion API calls
  3. Chunking: Automatically handles large content by splitting into chunks of 100 blocks (Notion API limit)

Note: When using create_notion_entry tool, you can override environment variables by passing pageId, databaseId, title, date, or project as parameters.

MCP Integration:

  • Connects to Notion MCP server via Docker stdio transport
  • Uses append-blocks tool (preferred) or create-page tool
  • Handles parameter serialization correctly
  • Non-blocking: errors don't fail session close

Optional Files

The server works with or without these files:

  • .agent-os/session-summary.md - Session history (created if missing)
  • .agent-os/product/roadmap.md - Product roadmap (updated if present)
  • .agent-os/product/decisions.md - Decision log (updated if present)
  • claude.md, gemini.md, agents.md, .cursor/context.md - Context files

Development

Run in Development Mode

npm run dev

Build

npm run build

Start Production Server

npm start

Troubleshooting

MCP Server Not Found

  • Verify the path in Cursor MCP config is correct
  • Use forward slashes or escaped backslashes on Windows
  • Check that dist/index.js exists after building

Git Commit Fails

  • Ensure git is initialized: git init
  • Configure git user: 
    git config user.name "Your Name"
git config user.email "your.email@example.com"
  • Check you have write permissions

Context Files Not Syncing

  • Verify write permissions in the workspace directory
  • Check that no other processes are locking the files
  • Ensure the workspace path is correct

Session Summary Not Updating

  • Check that .agent-os directory exists (created automatically)
  • Verify write permissions in the workspace
  • Look for errors in Cursor's MCP logs

Notion Entry Not Creating

  • Verify NOTION_API_TOKEN is set correctly
  • Check that NOTION_PAGE_ID or NOTION_DATABASE_ID is configured
  • Ensure Docker can run mcp/notion:latest container
  • Check Docker logs: docker logs mcp-notion (if running as container)
  • Verify Notion integration has access to the target page/database
  • If MCP fails, check if Python fallback script exists and is executable
