Best for
  • AI assistants that need calendar integration
  • Users with CalDAV-compatible servers
  • Scenarios requiring task management
  • Developers, content creators, and project teams using Atlassian Cloud
  • Teams that want Atlassian access inside ChatGPT, Claude, Cursor, or VS Code
  • Users who need natural-language search, write, and cross-product workflows
Not for
  • Direct Google Calendar integration (non-CalDAV)
  • Users who need complex calendar permission management
  • Users with high security concerns who don't trust third-party MCP servers
  • Users without an Atlassian Cloud site or relevant product permissions
  • Deployments requiring a self-hosted MCP server
  • Users unwilling to grant an AI client access to Atlassian data or actions
  • Jira Service Management or Bitbucket Cloud workflows requiring OAuth authentication
Required permissions
  • Requires access to CalDAV server credentials (username and password)
  • Requires read and write capabilities for calendars and tasks
  • Jira and Confluence provide read, write, and search permission groups
  • Jira Service Management provides read and write access through API tokens only
  • Bitbucket Cloud provides read and write access through scoped API tokens only
  • Compass is available through OAuth 2.1 only
  • The first OAuth installer for a site must have access to the Atlassian apps requested by the MCP scopes
  • Organization administrators can manage domain controls, API-token authentication, app access, and audit logs
Risks and side effects
  • Credential leakage: password may be stored in configuration
  • If the MCP client is maliciously controlled, calendar data could be modified or deleted
  • AI clients can perform Jira, Confluence, Jira Service Management, Bitbucket, and Compass actions on the user’s behalf
  • Prompt injection, indirect prompt injection, and tool-poisoning attacks may cause data exfiltration or unintended changes
  • Use least privilege, scoped tokens, and minimal project or workspace access
  • Require human confirmation for high-impact or destructive actions and monitor audit logs
