Cursor official plugin library fully open source: 100 + plugins put Gmail, GitHub, Salesforce, Playwright into the editorCursor 官方插件库全量开源：100+ 插件把 Gmail、GitHub、Salesforce、Playwright 接进编辑器

The editor plug-in of the Agent era is no longer just "completing the code", but "connecting the outside world": letting the agent read your email, check your CRM, flip through your meeting minutes, and click through the page in the real browser.

The problem is that everyone needs to connect to a different system, and the cost of zero-write plug-ins is high, and most integration code is actually repetitive - authentication, paging, error retry, schema definition, and the routine is almost the same.

Cursor's approach is to open-source the entire plug-in market as a reference implementation: how to officially write the authentication and paging of the Gmail plug-in, how to write the browser control of the Playwright plug-in, and you can read the source code directly.

A more practical scenario for the team is a private plug-in: wrap the company's internal knowledge base, ticket system, and publishing platform into a plug-in according to the same structure, so that the agents in the editor really understand your business.

Development class (Cursor official): Thermos Thermonuclear Branch Review, PR Review Canvas, Docs Canvas, Ralph Loop self-referential iterative loop, Cursor SDK, Orchestrate parallel multi-agent orchestration, Advisor consults stronger models, Agent Compatibility Scanning, CLI for Agents, Create Plugin Scaffolding, Origin Apps.

Productivity classes: Gmail, Google Drive, Google Calendar, Google Docs, Google Sheets, Google Slides, Microsoft Teams, SharePoint.

Integration classes (the largest number, accounting for the largest number of warehouses): GitHub, Playwright, Salesforce, HubSpot, Intercom, Zoom, X, Excalidraw, BigQuery, Statsig, Shopify, QuickBooks, Workday, Square, and Coinbase, Robinhood, eToro, Interactive Brokers, Webull, S&P Global, Daloopa, Mercury, Brex, Xero in the financial direction.

Marketing & Sales Operations: Ahrefs, Semrush, Klaviyo, Customer.io, MailerLite, Brevo, Typeform, Jotform, Hunter, Attio, Outreach, Amplemarket, Profound, Clay, Ashby, Workable, Juicebox, Upwork, GoDaddy.

It can be seen that Cursor's ambition is not just programming: this is a set of "editor is the workbench" integration list, many of which plug-in Chinese users can not use, but the structure is completely reusable.

The repository is a typical multi-plugin market structure: the .cursor-plugin/marketplace.json of the root directory lists all the plugins, and each plugin places a list of .cursor-plugin/plugin.json in its own directory.

The single plugin directory consists of four parts: skills/release skills (SKILL.md with frontmatter), rules/release Cursor rules (.mdc file), mcp.json declares the MCP server required by the plugin, and README.md, CHANGELOG.md and license.

This means that a plugin can provide both “model auto-triggered knowledge” and “user explicitly invoked commands” without interfering with each other - this is also the most worthwhile layer to learn when copying.

All plugins are licensed by mit at the repository level. The author field (Cursor official is plugins@cursor.com) is also marked in the README form, and the third-party contributor is individually signed, so that it is easy to determine who is maintaining the plugin.

The following is the complete source code package of the main branch of the repository. After unzipping, it is the full plug-in directory, which can be read, copied, and transformed directly.

The easiest way to do this is to search for the installation directly in the plugin/marketplace panel in the Cursor editor, and the store version will automatically follow the update; the local package is more suitable for people who want to change the code or access the private system.

Path to a private plugin: Copy a simple plugin directory and → change the name and description in plugin.json → Rewrite skills under SKILL.md and mcp.json Point to your own → service Register in marketplace.json to load it natively.

Note that MCP-related integration plugins require you to prepare your own credentials and permissions for the corresponding service. Only the connection method is provided in the warehouse, and no account data is included.

This site organizes resources from the GitHub open source repository cursor/plugins (mit license), only for learning exchanges. Integration plugins will require you to authorize third-party services (email, CRM, brokerage accounts, etc.). Please verify the scope of permission on the test account before using it for real accounts. Especially careful when dealing with trading plugins (such as brokers, payment). It is recommended to always keep manual confirmation. The contents of this article are compiled from public information, and the specifics are subject to the official description of the project.
