Export to MCP server

# Start MCP server exposing all installed packages as tools
anyclaw mcp

# Expose a single package
anyclaw mcp hackernews

Add to your Claude Code / Cursor MCP settings:

{
  "mcpServers": {
    "anyclaw": {
      "command": "anyclaw",
      "args": ["mcp"]
    }
  }
}

Or expose a single package:

{
  "mcpServers": {
    "hackernews": {
      "command": "anyclaw",
      "args": ["mcp", "hackernews"]
    }
  }
}

Generate Skills for Claude Code

# Generate SKILL.md for all installed packages
anyclaw skills

# Generate for a specific package
anyclaw skills hackernews

# Generate to a custom directory
anyclaw skills hackernews -o ~/.claude/skills/hackernews

Browser Extension

Some packages require browser access (e.g., Reddit, Bilibili). anyclaw includes its own browser extension and daemon for this.

Setup

1. Open chrome://extensions in Chrome
2. Enable Developer Mode
3. Click Load unpacked → select the extension/ directory from this repo

Usage

The daemon starts automatically when a browser command is needed. You can also manage it manually:

anyclaw daemon start     # start daemon (foreground)
anyclaw daemon status    # check daemon & extension status
anyclaw daemon stop      # stop daemon

How it works

Chrome (real browser, with cookies & login state)
    │
AnyClaw extension (background.js)
    │ WebSocket
    ▼
AnyClaw daemon (auto-started, port 19825)
    │ HTTP
    ▼
AnyClaw CLI (anyclaw run pkg cmd)

The extension runs commands in an isolated Chrome window, separate from your normal browsing. Sessions auto-close after 30 seconds of inactivity.

Package Formats

anyclaw supports four YAML formats. See examples/ for complete examples.

OpenAPI spec (examples/openapi.yaml)

Standard OpenAPI 3.x — any existing spec works:

openapi: 3.0.0
info:
  title: Translator
servers:
  - url: https://api.mymemory.translated.net
paths:
  /get:
    get:
      operationId: translate
      parameters:
        - name: q
          in: query
          required: true
          schema:
            type: string

Pipeline (examples/web.yaml)

Declarative data pipeline for fetching web data:

anyclaw: "1.0"
name: hackernews
description: Hacker News data tools
commands:
  - name: top
    description: Top stories
    args:
      limit:
        type: int
        default: 20
    pipeline:
      - fetch:
          url: https://hacker-news.firebaseio.com/v0/topstories.json
      - limit: ${{ args.limit }}
      - map:
          id: ${{ item }}
      - fetch:
          url: https://hacker-news.firebaseio.com/v0/item/${{ item.id }}.json
      - map:
          title: ${{ item.title }}
          score: ${{ item.score }}

CLI wrapper (examples/cli.yaml)

Wrap existing CLI tools with templated commands:

anyclaw: "1.0"
name: git-helper
description: Git shortcuts
commands:
  - name: recent
    description: Show recent commits
    args:
      count:
        type: int
        default: 10
    run: "git log --oneline -n {{count}}"

Script (examples/script.yaml)

Inline Python or Node.js scripts:

anyclaw: "1.0"
name: ip-tools
description: IP address utilities
commands:
  - name: myip
    description: Get your public IP
    script:
      runtime: python
      code: |
        import urllib.request, json
        data = json.load(urllib.request.urlopen("https://ipinfo.io/json"))
        print(json.dumps({"ip": data["ip"], "city": data["city"]}, indent=2))

Commands

Command	Description
anyclaw list	List installed packages and commands
anyclaw list --all	Browse all available packages from registry
anyclaw list --all --page N	Paginate registry packages
anyclaw search <keyword>	Search packages by name, description, or tag
anyclaw install <name|url|file|dir>	Install a package
anyclaw uninstall <name>	Remove a package
anyclaw run <pkg> <cmd> [flags]	Run a command

anyclaw auth <pkg> <api-key>	Set API key for a package
anyclaw daemon start|stop|status	Manage browser bridge daemon

Agent Integration

anyclaw ships with a SKILL.md at the project root that teaches AI agents how to use anyclaw. Link it to your agent's skills directory:

# Claude Code
ln -s /path/to/anyclaw/SKILL.md ~/.claude/skills/anyclaw/SKILL.md

# Or generate skills for individual packages
anyclaw skills hackernews
# → ~/.anyclaw/skills/hackernews/SKILL.md

Registry

The package registry indexes 30+ packages from multiple sources:

• anyclaw native — packages maintained in this repo
• community — compatible YAML pipeline packages from the ecosystem
• third-party plugins — community-contributed packages

To add a package to the registry, submit a PR adding an entry to registry/index.yaml.

Packages not in the registry can still be installed directly by URL:

anyclaw install https://github.com/user/repo

Credits

anyclaw's pipeline format is inspired by and compatible with opencli by @jackwener. The anyclaw registry references several community packages from the opencli project. Thanks to opencli and its contributors for building a great collection of data tools.
