Serveur MCP agentsync

Languages: English | 简体中文

agentsync

One command to share rules, skills, and MCP configs across your AI tools.

Keep one copy across Claude Code, Codex, OpenCode, Gemini CLI, Qwen Code, Copilot CLI, Kimi Code, Grok CLI, Amp, Crush, Goose, Factory Droid, iFlow, Kilo, Pi, dsh, Cursor, Windsurf, Zed, CodeBuddy, Qoder, Junie, Kiro, JoyCode, and Aider Desk, plus the shared ~/.agents entry. A lightweight standalone binary.

A real Claude Code + Codex run; output excerpted for readability.

Install

Windows — PowerShell:

irm https://raw.githubusercontent.com/x0c/agentsync/main/install.ps1 | iex

macOS / Linux — shell:

curl -fsSL https://raw.githubusercontent.com/x0c/agentsync/main/install.sh | sh

The installers download the matching release archive (agentsync_windows_<arch>.zip on Windows, agentsync_<os>_<arch>.tar.gz on macOS/Linux) and verify its SHA-256 checksum before installing. AGENTSYNC_INSTALL_DIR overrides the default (%LOCALAPPDATA%\Programs\agentsync\bin on Windows, ~/.local/bin on macOS/Linux); the Windows installer adds it to the user PATH.

macOS / Linux — Homebrew:

brew install --cask x0c/tap/agentsync

Any OS — Go 1.25.8+:

go install github.com/x0c/agentsync@latest

Add Go's bin directory to PATH if needed (usually ~/go/bin; %USERPROFILE%\go\bin on Windows).

Without an installer or Go: download and extract a release binary, then put it on PATH. Available for macOS and Linux (arm64 / amd64), and Windows (arm64 / amd64). Checksums are included.

Run

First preview, then apply:

agentsync --check
agentsync

That's it. agentsync merges your existing instructions, collects your skill folders, and imports your MCP servers into one shared source — then links or writes them back to each installed tool in its native format. Files replaced during sync are backed up automatically; tools you haven't installed are skipped.

From then on, maintain these files in ~/.config/agentsync/ (%USERPROFILE%\.config\agentsync\ on Windows):

File	What you manage once
AGENTS.md	Global instructions
skills/	Complete skill folders, including scripts and references
mcp.json	MCP servers

Run agentsync again after changes, or use the optional watcher below.

Optional commands

Need	Command
Preview without writing	agentsync --check
Automatically apply source changes	agentsync --watch
Restore the latest backup	agentsync --rollback latest
Link a project's CLAUDE.md to its AGENTS.md	agentsync --repo
Print the version	agentsync --version

See the workflow guide for background services, batch repository sync, filters, and backup details.

Good to know

• Default sync manages global configuration on this machine. Project files are handled by the separate repository mode.
• Support varies by tool. See instruction and skill support and MCP support.
• Instructions and skills use links where possible. Cursor gets a managed .mdc rule; on Windows, skill directories link as a symbolic link first, then an NTFS directory junction, otherwise agentsync reports an error naming Windows Developer Mode. See Cursor loading limits.
• Exclude servers, skills, or instructions per tool with a sync-policy.json beside the canonical sources; see filtering. Filtering never removes content from the canonical source.
• Edit the shared source. The watcher pushes changes out to your tools; it does not import edits made in another tool's settings. Keep mcp.json local: it may contain tokens and machine-specific paths. .gitignore / .stignore entries protecting mcp.json are written only when the configuration directory is already a Git repository (.git) or a Syncthing folder (.stfolder).
• Safety checks reject unsupported arguments, invalid MCP entries, and unsafe skill-directory overlaps. Your own rules are merged in before copies are generated; Codex servers that share a name keep their local restrictions and authentication options. Rollbacks use collision-resistant backup snapshots, and latest skips backups with no file changes. See the preservation boundaries.
