| Best for | - Individuals and teams needing access to several Google Workspace services.
- Developers deploying by tool tier, service, or permission scope.
- Organizations needing self-hosted, multi-user OAuth 2.1, or container deployments.
- Developers who want to call MCP tools through a CLI.
| - 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
| - Internal collaboration workflows that need channel history or team notifications
- Development teams testing message automation in a non-production workspace
|
|---|
| Not for | - Users requiring a server maintained by Google.
- Users with only a personal @gmail.com account who need Google Chat.
- Users unwilling to configure Google Cloud OAuth credentials or APIs.
- Applications seeking unauthorized access to Google Workspace data.
| - 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
| - Organizations that prohibit model access to internal chat history
- Workspaces that cannot tightly restrict bot channels and OAuth scopes
|
|---|
| Required permissions | - Requires Google Cloud OAuth client credentials.
- OAuth scopes depend on the enabled services and tools.
- Supports read-only scopes, per-service granular permissions, and full access.
- Write tools for Drive, Gmail, and other services require corresponding write permissions.
- Google Chat requires a configured Chat app and a Google Workspace account.
- Optional service-account mode requires service-account credentials and domain-wide delegation.
| - 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
| - A Slack Bot Token and Team ID
- Least-privilege OAuth scopes for channel history, messages, or reactions
|
|---|
| Risks and side effects | - Full tools and write scopes may allow modifying, sending, deleting, or sharing user data.
- For public deployments, unrestricted dynamic-client redirect URIs can create a phishing risk.
- Stdio is a legacy fallback; OAuth 2.1 is recommended for remote or shared deployments.
- Local attachments and credential stores write to configured local directories; stateless mode avoids file writes.
- Google API quotas, OAuth consent configuration, and account permissions may limit functionality.
- The Chat API is unavailable for personal Gmail accounts.
| - 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
| - Channel history may contain internal or personally sensitive information
- Messages and reactions are visible to real members; confirm channel and content before writes
