# Slashy MCP Overview

> What Slashy MCP is, why to use it, and what you need before setup.

Slashy MCP lets your favorite AI tools - Claude Code, Claude Desktop, Cursor, and Codex - use Slashy's email, calendar, and research tools directly. This section walks you through the basics before you pick a client to set up.

## What does Slashy MCP do?

Slashy MCP gives any MCP-compatible AI assistant access to Slashy's toolset:

* **Email automation** - draft, send, reply, schedule, label, and attach files through your Slashy account
* **Calendar automation** - create events, check availability, propose meeting times
* **Contact research** - enrich leads with LinkedIn, company data, and news
* **Meeting prep** - pull attendee profiles and email history
* **Reminders + triggers** - create scheduled workflows from chat

See [Using Slashy MCP](/how-to-guides/slashy-mcp-using) for ready-made example prompts covering each of these.

## Why use it?

* **Work where you already work.** Trigger Slashy actions from Claude, Cursor, or Codex without switching apps.
* **One login.** OAuth 2.1 with PKCE - no API keys to copy, rotate, or leak.
* **Always current.** Tools update automatically on Slashy's side; your client picks them up.

## Prerequisites

Before you start, make sure you have:

* A **Slashy account** signed in with Google. [Sign up at slashy.com](https://slashy.com) if you haven't.
* One of the supported clients installed:
  * Claude Code
  * Claude Desktop
  * Cursor
  * Codex CLI
* A browser available on the same machine (OAuth opens a login window).

<Note>Slashy MCP uses **OAuth 2.1 with PKCE**. You log in through your browser once - no manual tokens, no config files with secrets.</Note>

    Add the Slashy [skill / rules file](/how-to-guides/slashy-mcp-skills) to your client so it always reaches for Slashy MCP when you mention email, calendar, research, or scheduling - no more repeating "use Slashy" in every prompt.
  </Step>

    Try a [ready-made prompt](/how-to-guides/slashy-mcp-using) - triage your inbox, draft a reply, prep for tomorrow's meetings, attach a file from Drive, or get Slashy links to open threads in the app.
