mcplink

Universal MCP config sync daemon. One source of truth, all agents stay in sync.

Problem

Every AI agent stores MCP config in its own path with its own schema. Add a server once → edit 6 files.

Solution

.agents/mcp.json is the single source of truth. mcplink watches it and propagates every change to all agents automatically.

Supported agents

Agent	Config path	Key
Cursor	.cursor/mcp.json	mcpServers
Claude Code	.mcp.json	mcpServers
Copilot	.github/mcp.json	mcpServers
VS Code	.vscode/mcp.json	servers
Devin Desktop (formerly Windsurf)	.windsurf/mcp.json	mcpServers
OpenCode	opencode.json	mcp

Usage

# First run — installs as system service
mcplink

# Commands
mcplink status    # Show daemon status and synced agents
mcplink sync      # Force sync now
mcplink agents list  # Show agents installed on this OS
mcplink als          # Alias for agents list

  "servers": {
    "memlink": {
      "transport": "http",
      "url": "https://memlink.cloud/mcp",
      "headers": {
        "Authorization": "Bearer TOKEN"
      }
    },
    "filesystem": {
      "transport": "stdio",
