Membrane Application Skills

A skill set that teaches an agent to work with Gmail, Slack, HubSpot, Salesforce and other apps through the Membrane CLI

Skill

High risk

We rate an entry high when the tool writes to external systems, handles money, production databases or secrets, or runs arbitrary commands. The CLI installs it only with your consent.

Why this level

  • The skills perform actions in mail, chats and CRMs on your behalf
  • They require login to third-party services and a Membrane account

Install

Manual install

npm install -g @membranehq/cli@latest

The Membrane CLI that the skills call to reach apps. After install run membrane login.

This is third-party code. Review the repository files before installing.

What it does

The repository gathers one skill per app: each skill describes the service's entities, the available actions, and when to use which. Every SKILL.md is written for Membrane CLI calls, and Membrane handles login, keys and token refresh. Once you install the skill for an app, the agent can run actions there: send an email, create a task, append a spreadsheet row. The skills follow the open Agent Skills spec, so different agents can use them.

Who it is for. For developers and teams who need to connect an agent to work services without hand-wiring authorization.

Good fit when

  • You want the agent to run actions in Gmail, Slack, a CRM or another external service
  • You want ready descriptions of an app's entities and actions instead of a raw API
  • You work across several services and want one connection path

Not a fit when

  • You are not ready to create a Membrane account and install its CLI
  • You need direct API access to the service without an intermediary
  • The app you need is not among the folders in skills/

Example request

Using the gmail skill, list my last ten emails and draft a reply

Limitations

The skills are not self-contained: they work only through the Membrane CLI (an npm package) and require a Membrane account, with a free tier. You authorize each service in the browser. Availability of the platform and the connected services from Russia without a VPN is not guaranteed and should be checked per app.

How to disable. Remove the skill folder from the agent's skills directory and, if needed, uninstall the CLI: npm uninstall -g @membranehq/cli.

Security check

  • The skills perform actions in mail, chats and CRMs on your behalf
  • They require login to third-party services and a Membrane account

README in short

The README frames the collection as thousands of skills, one per app. Each skill describes the service structure, actions and hints on when to call what, and relies on the Membrane CLI for authorization. It claims compatibility with Claude Code, Cursor, Codex, GitHub Copilot, Gemini CLI and other Agent Skills spec agents. Install by app name via npx skills add or by copying the folder. MIT licensed.
