How to Set Up and Use Keyboard Local
Keyboard Local is a privacy-first MCP server and desktop application that lets AI assistants control third-party applications and APIs installed on your machine — including Gmail, Google Calendar, Slack, Linear, Jira, Notion, GitHub, Stripe, and more — without sending your credentials to any cloud service. It runs as a local MCP server paired with an Approver Client desktop app that intercepts every action for human approval before execution, keeping you in control of what the AI can do. Developers and power users who want a single, secure AI integration layer across all their tools will find it ideal.
Prerequisites
- Node.js 18 or later and npm installed
- Git for cloning the monorepo
- API keys for the third-party services you want to connect (e.g. Gmail OAuth credentials, Slack token, Linear API key)
- An MCP-compatible client such as Claude Desktop or Claude Code
Clone the keyboard-local monorepo
The project is a monorepo containing both the Approver Client desktop app and the MCP server. Clone it recursively to include any submodules.
git clone --recursive https://github.com/keyboard-dev/keyboard-local.git
cd keyboard-localStart the Approver Client desktop app
The Approver Client shows a UI that prompts you to approve or deny each action the AI wants to take. Start it in development mode.
cd apps/approver-client
npm install && npm run devBuild and start the MCP server
In a separate terminal, build the keyboard-mcp server and start it so it can accept connections from your AI client.
cd apps/keyboard-mcp
npm install && npm run buildConnect your third-party services
In the Approver Client UI, connect the services you want Claude to control (e.g. Gmail via OAuth, Slack via a bot token). Your API keys are stored locally — they are never sent to external servers.
Register the MCP server with your AI client
Add the keyboard-mcp server to your Claude Desktop or Claude Code configuration so Claude can discover the available tools.
Keyboard Local Examples
Client configuration
Register the locally built keyboard-mcp server with Claude Desktop. Point the command at the built entry point inside the apps/keyboard-mcp directory.
{
"mcpServers": {
"keyboard-local": {
"command": "npx",
"args": ["keyboard-local"]
}
}
}Prompts to try
Once services are connected, use Claude to automate tasks across your tools. Each action will prompt you for approval in the Approver Client.
- "Draft and send an email to [email protected] summarizing today's meeting notes"
- "Create a Linear issue titled 'Fix login bug' assigned to me with high priority"
- "List my upcoming Google Calendar events for the next 3 days"Troubleshooting Keyboard Local
The Approver Client does not show approval prompts when Claude takes an action
Ensure both the Approver Client app and the MCP server are running simultaneously. The MCP server communicates with the Approver Client over a local socket — if the Approver Client is closed, actions may be blocked silently.
A connected service returns authentication errors
Re-connect the service in the Approver Client UI to refresh OAuth tokens or re-enter API keys. OAuth tokens expire; reconnecting will generate a fresh token. Check the service's developer dashboard to ensure the app credentials are still active.
npm run build fails in apps/keyboard-mcp
Make sure you are using Node.js 18 or later. Run 'node --version' to confirm. Delete node_modules and package-lock.json, then run 'npm install' again before building.
