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 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

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. Update Agent OS roadmap and decisions (if present)
4. Sync all context files (claude.md, gemini.md, agents.md, .cursor/context.md)
5. 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"

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

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

Why Use This?

Automated Workflow

• No Manual Steps: Automatically syncs, updates, and commits
• Consistent Format: Standardized session summaries and git commits
• Time Saver: Closes sessions in seconds, not minutes

Context Continuity

• Unified Context: All AI assistants see the same project context
• Cross-Session Memory: Session summaries persist across restarts
• Decision Tracking: Maintains history of why decisions were made

Git Integration

• Automatic Commits: Never forget to commit your work
• Descriptive Messages: Auto-generated commit messages with context
• Clean History: Organized commits at natural breakpoints
