These extensions connect agents to the documents, files, calendars, projects, and office suites where your work already lives. The recurring decision: grant broad access for cross-service reach, or scope a single connector tightly and keep authorization simple.

Google Workspace CLI logo
## [Google Workspace CLI](https://github.com/googleworkspace/cli)
Scriptable access to all of Workspace
500Kestimated installs
**What it is** One command-line interface sits over the full set of Google Workspace APIs, bundled with portable skills, helpers, personas, and recipes that agents can call. A single authenticated surface reaches Gmail, Drive, Calendar, Sheets, Docs, Slides, Chat, Tasks, Meet, and Forms.
**When to use** Reach for it when an agent needs broad, scriptable access across several Workspace products, with structured JSON output and dry-run support. Setup is heavier than a managed connector, broad OAuth scopes expose a lot, and the project is unsupported and pre-1.0, so expect breaking changes.
**What you need** Your Google account, authenticated once through the CLI.
Install CLI
Notion logo
## [Notion](https://developers.notion.com/guides/mcp/overview)
Notion pages, databases, and capture
350Kestimated installs
**What it is** Notion connects an agent to your workspace and layers on structured workflows for knowledge capture, meetings, research, specifications, tasks, pages, and databases. The agent can search and synthesize that context, then create or update pages and query databases.
**When to use** Useful when Notion is your system of record and you want the agent to capture decisions, prepare meetings, or turn a spec into implementation work. Grant only the pages and write access a task needs; workspace content can hold confidential material or hidden prompt-injection instructions.
**What you need** A Notion account and workspace.
Install PluginPluginPluginMCP
Google Calendar logo
## [Google Calendar](https://calendar.google.com)
Scheduling against your real calendar
320Kestimated installs
**What it is** Native calendar access that lets an agent check availability, schedule and update events, prepare meeting context, and manage attendees and invitations against your real calendar rather than a static copy of your week.
**When to use** The point is that the agent reasons over real commitments and turns a plan into scheduled events, rather than handing you a timetable to enter yourself. Current documentation describes creating, updating, and deleting events, though older beta notes still call it read-only, so confirm what your setup allows.
**What you need** Your Google account, via the host's connector.
Install ConnectorPlugin
Outlook Calendar logo
## [Outlook Calendar](https://www.microsoft.com/microsoft-365/outlook/calendar-app)
Meeting prep and Outlook scheduling
200Kestimated installs
**What it is** Access to Outlook events and availability. Inside Claude it lives within the Microsoft 365 connector, while Codex offers it as a dedicated calendar plugin. The agent can prepare meeting context, compare availability, flag conflicts, summarize the day, and make approved changes.
**When to use** Good for daily planning, meeting prep, and rescheduling. Because calendar writes reach real participants and their schedules, confirm before letting the agent act. Shared and delegated actions plus full write support depend on scopes and how the host is configured, so available actions vary.
**What you need** Your Microsoft account, reached via the Microsoft 365 connector on Claude.
Install ConnectorPluginMCP
Google Drive logo
## [Google Drive](https://drive.google.com)
Working across your Drive documents
170Kestimated installs
**What it is** Native access for searching and working across Drive, Docs, Sheets, Slides, PDFs, images, and uploaded files. The agent can pull current documents into its work and synthesize many files at once instead of you pasting each one in. Live reads and writes in Sheets ride in through this same Drive connection.
**When to use** It keeps work anchored to the current shared version of a document and lets generated files land back in Drive. Access mirrors the connected account's permissions, and text extraction can drop comments, suggestions, and embedded images, so treat it as reading the words, not the full file.
**What you need** Your Google account, via the host's connector.
Install ConnectorPlugin
Linear logo
## [Linear](https://linear.app)
Planning context from Linear issues
150Kestimated installs
**What it is** Linear's official integration brings issues, projects, comments, and release work into the agent. A coding agent gets the planning context behind a task and can create, triage, or update work without leaving the implementation environment.
**When to use** Most useful when Linear is your engineering and product system of record and you want implementation tied to the issues that drive it. Use a read-only token when the agent only needs context. Note this is connecting a coding agent to Linear, not Linear's own agent running sessions.
**What you need** A Linear account; a read-only token is enough when the agent only needs context.
Install ConnectorPluginPluginMCP
SharePoint logo
## [SharePoint](https://www.microsoft.com/microsoft-365/sharepoint/collaboration)
Governed company docs in SharePoint
150Kestimated installs
**What it is** Access to organizational SharePoint sites and files. Claude folds SharePoint and OneDrive into the Microsoft 365 connector, while Codex ships a dedicated plugin. The agent can find governed internal documents, synthesize many files, and prepare briefs or onboarding guides.
**When to use** It grounds answers and drafts in governed company content without gathering files by hand. Know the edges: OpenAI's app handles common Office files, PDFs, text, and CSV up to 100 MB but not SharePoint site pages, sync can lag, and encrypted files are excluded.
**What you need** Your Microsoft work account, reached via the Microsoft 365 connector on Claude.
Install ConnectorPluginMCP
Airtable logo
## [Airtable](https://www.airtable.com)
Structured records your team shares
150Kestimated installs
**What it is** Airtable's official integration connects an agent to bases, schemas, records, and shared operational workflows. The agent can read and manage structured data that your team continues to review and edit through familiar Airtable views.
**When to use** The value is that results land in a shared operational database, not a chat window, so trackers and project systems stay usable by the whole team. The agent inherits your Airtable role: read-only stays read-only, editors can change records, so keep access as narrow as the task allows.
**What you need** An Airtable account and base access.
Install PluginPluginMCP
Atlassian Rovo logo
## [Atlassian Rovo](https://www.atlassian.com/platform/rovo-mcp)
Jira, Confluence, and Bitbucket context
140Kestimated installs
**What it is** The official agent connection into Jira, Confluence, Compass, Jira Service Management, Bitbucket, and cross-product search. Bundled workflow skills cover task capture, turning specs into backlogs, status reporting, knowledge search, and issue triage.
**When to use** It hands agents your company's context and the ability to create or update work in place, so meeting notes or specs become trackable Atlassian artifacts. Actions follow your existing permissions, but tools can still modify issues and pages, and the service does not meet FedRAMP or HIPAA requirements.
**What you need** An Atlassian account with the products you use.
Install PluginPluginPluginMCP
Asana logo
## [Asana](https://asana.com)
Team tasks and projects in Asana
130Kestimated installs
**What it is** Asana's official integration lets an agent search, create, update, and coordinate tasks, projects, goals, and comments, working directly against your real workspace rather than a copy of it.
**When to use** It turns a conversation or plan into shared team work while keeping Asana's owners, dates, permissions, and visibility intact, so nothing stays trapped in a chat transcript. Each token is scoped to a single workspace, which keeps access contained but means one connection covers one workspace.
**What you need** An Asana account and workspace.
Install PluginPluginMCP
Calendly logo
## [Calendly](https://claude.com/connectors/calendly)
Booking links and availability
95Kestimated installs
**What it is** Calendly's official integration lets an agent work with your scheduling: event types, availability, scheduling links, bookings, and cancellations. Claude uses a connector; Codex ships a plugin built on the Calendly app.
**When to use** Good when scheduling should happen in the conversation - creating a link, checking availability, or moving a booking - instead of a trip through Calendly. Bookings and cancellations reach real invitees, so confirm them first.
**What you need** A Calendly account.
Install ConnectorPlugin
Monday.com logo
## [Monday.com](https://claude.com/connectors/monday)
Boards and items in monday.com
80Kestimated installs
**What it is** Monday.com's official integration connects an agent to your work management: boards, items, columns, assignments, timelines, updates, and progress insights. Claude uses a connector; Codex ships a plugin built on the monday.com app.
**When to use** A fit when monday.com is where your team tracks work and you want an agent to inspect and update it without opening the product. Board and item changes are real writes, so confirm consequential ones before the agent runs them.
**What you need** A monday.com account and workspace.
Install ConnectorPlugin
Miro logo
## [Miro](https://developers.miro.com/docs/miro-mcp)
Boards, diagrams, and visual context
80Kestimated installs
**What it is** Miro's official integration connects an agent to collaborative boards. It reads and searches boards and creates or updates boards, diagrams, docs, tables, comments, and images, backed by Miro's hosted MCP and packaged with visual-context skills. Official packages cover Claude, Codex, and Cursor.
**When to use** Reach for it when Miro is your team's shared visual workspace and you want an agent to pull design or strategy context and produce diagrams and workshop boards in place. Note the MCP is Enterprise-only and still in public beta, so an admin has to enable it, and installing a plugin plus a separate MCP for the same client will collide.
**What you need** A Miro account with OAuth; the MCP requires an Enterprise plan an admin enables.
Install PluginPluginPluginMCP
ClickUp logo
## [ClickUp](https://clickup.com)
Tasks, Docs, and time in ClickUp
80Kestimated installs
**What it is** ClickUp's official hosted service connects an agent to tasks, Docs, members, comments, time tracking, and Chat. In one place it can search workspace context, create and route tasks, build status reports, update Docs, log time, and post updates.
**When to use** A fit for project coordination, status reporting, task routing, and time tracking without leaving the agent. Keep in mind the connection can write to your workspace, and ClickUp's public API does not preserve every rich Docs formatting feature, so complex documents can lose some structure.
**What you need** A ClickUp account and workspace.
Install ConnectorAppPluginMCP
Dropbox logo
## [Dropbox](https://www.dropbox.com)
Files found, summarized, and saved back
75Kestimated installs
**What it is** Dropbox connects an agent to your files and folders. It can find and summarize documents, synthesize several at once, save generated work back, organize folders, and create sharing links without moving files by hand.
**When to use** Useful for grounding work in shared files and returning finished output to the same place your team already looks. Two limits worth knowing: managed workspaces may require admin approval, and OpenAI's sync skips images, video, archives, and design files.
**What you need** A Dropbox account.
Install PluginPlugin
DocuSign logo
## [DocuSign](https://developers.docusign.com/tools/mcp-server/)
Agreements found, sent, and tracked
70Kestimated installs
**What it is** DocuSign's official integration brings agreement workflows into an agent: finding, reviewing, creating, sending, and managing agreements. Claude uses a connector, Codex a plugin built on the DocuSign app, with an official MCP server documented for other clients.
**When to use** Use it when contracts live in DocuSign and you want their context and actions inside the agent workflow. Sending agreements and triggering workflows are consequential, and legal review still applies, so keep sends behind confirmation.
**What you need** A DocuSign account.
Install ConnectorPluginMCP
Box logo
## [Box](https://claude.com/connectors/box)
Governed enterprise content in Box
50Kestimated installs
**What it is** Box's official integration gives an agent governed access to enterprise content in Box: searching and reading files, answering questions over documents, extracting metadata, and - where permissions allow - creating files and folders, adding collaborators, and making shared links. Claude uses a connector, Codex a first-party plugin, with an official remote MCP for other clients.
**When to use** Use it when your documents live in Box and existing access policies should keep governing what an agent can see and do. Operations stay bounded by Box permissions, but writes and sharing links still deserve review before you allow them.
**What you need** A Box account; organizations may prefer Admin Console setup.
Install ConnectorPluginMCP
## Choose by use case

One broad surface, or a connector scoped to one service?

→ Google Workspace CLI - one scriptable, authenticated surface across Gmail, Drive, Calendar, Sheets, Docs, and the rest; heavier setup, broad OAuth scopes, and still pre-1.0

Everything below scopes to a single service - simpler authorization and a smaller blast radius.

Reading and writing the files and documents where your work lives?

→ Google Drive - native access across Drive, Docs, Sheets, and Slides, with generated files saved back

→ SharePoint - governed company documents, via the Microsoft 365 connector on Claude

→ Box - enterprise content that stays inside your existing Box permissions

→ Dropbox - find and synthesize shared files, then save finished work back in place

Mostly dictated by your stack. Building slides? See the Presentations tools on the Design & UI page.

Keeping structured records your team keeps editing?

→ Notion - pages, databases, and structured capture when Notion is your system of record

→ Airtable - operational records the whole team keeps reviewing through familiar views

Coordinating tasks and project work?

→ Linear - engineering issues and planning context pulled into coding sessions

→ Atlassian Rovo - Jira, Confluence, and Bitbucket with cross-product search and workflow skills

→ Asana - team tasks, projects, and goals against your real workspace

→ ClickUp - tasks, Docs, time tracking, and status in one workspace

→ Monday.com - boards, items, and work management

Usually dictated by your team's tracker, not chosen freely.

Scheduling against real calendars?

→ Google Calendar - availability, events, and meeting prep on your Google calendar

→ Outlook Calendar - the same on Microsoft, via the Microsoft 365 connector on Claude

→ Calendly - booking links and availability when others schedule time with you

Visual boards and diagrams?

→ Miro - pull design and strategy context from boards and produce diagrams in place (Enterprise-only MCP, still in beta)

Contracts and agreements?

→ DocuSign - find, review, send, and track agreements, with sends kept behind confirmation
