Devsync

MCP server for AI-merge of team dev configurations. Works with any MCP-capable IDE (Claude Code, Cursor, Windsurf, Copilot, Zed, etc.).

What it does

Teams maintain a shared config profile repo (shell configs, git settings, AI rules, editor configs). devsync-mcp provides MCP tools that let the IDE's LLM intelligently merge team configs with your personal configs — preserving your customizations while incorporating team standards.

Key insight: The MCP server does NOT call an LLM. It provides source and target content to the host IDE's LLM, which performs the intelligent merge.

Install

pip install devsync-mcp

MCP Configuration

Add to your IDE's MCP settings:

{
  "mcpServers": {
    "devsync-mcp": {
      "command": "devsync-mcp",
      "transport": "stdio"
    }
  }
}

Tools

Tool	Purpose
pull_team_profile	Clone/pull team config repo
list_profile_configs	List configs in a profile
detect_current_configs	Scan environment for existing configs
preview_merge	Return source + target for LLM merge
apply_merge	Write merged content with backup
sync_all	Pull latest + present merge plan
list_backups	List previous merge backups
restore_backup	Restore from backup
get_merge_status	Show merged/pending/changed status

AI-Merge Flow

1. pull_team_profile(git_url)     → downloads team config repo
2. list_profile_configs(profile)  → shows available configs
3. detect_current_configs()       → finds your existing configs
4. preview_merge(profile, config) → returns {source_content, target_content}
5. HOST LLM reads both, produces intelligent merge
6. apply_merge(target, merged)    → writes with backup

Team Profile Format

Create a devsync-profile.yaml in your team config repo:

name: acme-team-config
description: ACME Corp standard dev environment
version: 1.0.0

configs:
  - name: zshrc-additions
    file: shell/zshrc-additions.sh
    target: ~/.zshrc
    type: shell_profile
    description: Team shell aliases and PATH additions

  - name: claude-rules
    file: ai-rules/claude-rules.md
    target: CLAUDE.md
    type: ai_rules
    description: Team coding standards for Claude Code

Config Types

• shell_profile — .zshrc, .bashrc, .bash_profile, .profile
• git_config — .gitconfig, .gitignore_global
• editor_config — .editorconfig
• ai_rules — CLAUDE.md, .cursorrules, AGENTS.md, etc.
• vscode_settings — .vscode/settings.json, etc.
• ssh_config — .ssh/config
• custom — any file with explicit source/target mapping
