# Claude Co-Work

## What It Is

A desktop application/interface for Anthropic's Claude that allows for **deep integrations with local file systems and external APIs** via [[concept-custom-connectors-mcp|Custom Connectors (MCP)]]. It supports the creation of [[concept-claude-skills-d4|Skills]] (custom instruction sets) and is the primary environment [[entity-sabrina-ramonov|Sabrina Ramonov]] uses to run her content engine.

## Why It Matters

Claude Co-Work is the **runtime** for the entire workflow. Without it:

- You cannot store reusable Skills.
- You cannot grant Claude access to local files (e.g., the Downloads folder screenshot trick in [[claim-local-file-context|claim-local-file-context]]).
- You cannot install third-party MCP connectors like [[entity-blotato|Blotato]].

This is why [[prereq-claude-cowork-access|access to Claude Co-Work or Claude Desktop]] is the gating prerequisite for the entire system.

## Distinction From Web Claude

Standard web Claude supports file uploads but **not** arbitrary local filesystem listing or arbitrary MCP servers. Anthropic's deeper integrations (tools, filesystem, APIs) live in the desktop client.

## Canonical Presence

- Anthropic Claude: https://www.anthropic.com/claude
- Model Context Protocol: https://github.com/modelcontextprotocol

## Underlying Models

Claude 3 family (Opus, Sonnet, Haiku) with multimodal capabilities — chart, photo, and screenshot understanding power the [[claim-local-file-context|local-file-context]] capability.
