Slashy MCP is the bridge between Slashy and your AI tools. Once connected, Claude Code, Claude Desktop, Cursor, and Codex CLI can use Slashy’s tools directly - sending email, prepping meetings, enriching contacts, and scheduling - without switching apps.

How it works

Model Context Protocol (MCP) is an open standard for connecting AI assistants to external tools. Slashy runs an MCP server; your AI client talks to it over HTTP with OAuth 2.1 + PKCE. You log in once through your browser - no API keys, no config files with secrets.
