The 11 Official Claude Cowork Plugins: Which One to Choose?

How Claude Cowork plugins work

Cowork plugins are built on the MCP (Model Context Protocol), an open standard developed by Anthropic. Each plugin is an MCP server that exposes specific tools to Claude. When you install a plugin, Claude gains new capabilities: reading particular file formats, interacting with external APIs, or executing operations in third-party software.

Plugins are installed from the Cowork Marketplace in the interface, or via command line. Each requires initial configuration (usually an API key or OAuth authentication) then works transparently in your conversations.

1. Office Suite — Rating: 9/10

Read, create and modify Word, Excel, PowerPoint and PDF files. The most versatile plugin. Best use case: Transform a text brief into a formatted PowerPoint presentation, or analyze a 5,000-row Excel file for insights without writing a single formula. Preserves formatting, generates native Excel charts, and supports Word track changes. Large files (Excel > 50 MB) may slow the agent.

2. Marketing — Rating: 8/10

Connects to Google Analytics, Search Console, Meta Ads and Mailchimp. Best use case: Generate a weekly SEO performance report combining Search Console and Analytics data with automatic optimization recommendations. Does not yet support TikTok or LinkedIn Ads (planned Q3 2026).

3. Sales — Rating: 7/10

Integrates with HubSpot, Salesforce and Pipedrive. Best use case: Prepare a weekly pipeline review analyzing at-risk deals with action suggestions. Reads and writes to the CRM. Salesforce integration requires Enterprise API access.

4. Data — Rating: 9/10

Connects to SQL databases (PostgreSQL, MySQL, SQLite), BigQuery and CSV/Parquet files. Best use case: Explore an unknown database, understand its schema, and generate an analysis report with charts — all in natural language. Supports complex queries, generates Python charts, and offers configurable read-only mode. Databases with 200+ tables may be challenging to navigate.

5. Legal — Rating: 7/10

Specialized tools for contract review, clause analysis and document comparison with European and American legal references. Best use case: Compare two contract versions to identify modified, added or removed clauses with legal implications analysis. Does not replace professional legal advice.

6. Finance — Rating: 8/10

Connects to Xero, QuickBooks and Open Banking feeds. Best use case: Automate monthly bank reconciliation — Claude compares accounting entries with bank statements and flags discrepancies. Generates standardized balance sheets and P&L statements. Open Banking integration is EU/UK only for now.

7. HR — Rating: 6/10

Integrates with BambooHR, Personio and Workday. Best use case: Create an optimized job description from a recruitment brief with required skills, market salary range and suggested interview questions. Still young — Workday integration is in beta.

8. Ops — Rating: 7/10

Connects to Notion, Airtable, Zapier and Make. Best use case: Build a complete Make workflow that syncs new HubSpot leads to Notion, sends a Slack notification and creates an Asana task. Complex workflows (10+ steps) may need manual adjustments.

9. PM (Project Management) — Rating: 8/10

Integrates with Jira, Linear, Asana and GitHub Projects. Best use case: Transform a PRD into structured Jira tickets with acceptance criteria, point estimates and suggested assignment. Supports batch ticket creation with hierarchy and automatic sprint reports. GitHub Projects integration is more limited.

10. Design — Rating: 7/10

Connects to Figma. Best use case: Extract design tokens from a Figma file and generate a matching Tailwind CSS configuration. Generates React/HTML code from Figma components. Does not yet support Adobe XD or Sketch.

11. Dev — Rating: 9/10

Extends development capabilities with GitHub, GitLab, Docker and SSH integrations. Best use case: Automate the release workflow — Claude creates the release branch, updates the changelog, opens the PR, waits for CI, and merges after validation. Destructive operations require explicit confirmation.

Which plugin to choose first?

If you could only install one plugin, choose based on your primary activity:

• General office work: Office Suite (9/10) — essential for anyone working with documents.

• Software development: Dev (9/10) — automates repetitive developer workflow tasks.
• Project management: PM (8/10) — ideal for project managers and Scrum Masters.
• Digital marketing: Marketing (8/10) — centralizes your performance data.

According to Anthropic's data, the most popular combination is Office Suite + Data + your domain-specific plugin. This base covers the majority of professional needs and lets you get the most out of Claude Cowork from the first weeks of use.
