Overview

The MCP Teams Server enables integration with Microsoft Teams, allowing read/write operations on messages, threads, and team members via API calls.

The MCP Teams Server offers both read and write capabilities within Microsoft Teams. It's relatively safe if properly configured with restricted permissions and secure handling of environment variables. However, misconfiguration or exposure of secrets can lead to unauthorized modifications within Teams.

Performance will depend on the Teams API rate limits and the server's resources. Consider implementing caching and throttling to optimize performance.

Cost is primarily determined by the usage of the Microsoft Teams API, which may have associated costs depending on the usage volume.

Known Risks

!Exposure of TEAMS_APP_ID and TEAMS_APP_PASSWORD can lead to unauthorized access to Teams resources.
!Lack of input validation could allow injection attacks when creating or updating messages.
!Improperly configured permissions on the Teams application could grant excessive access.
!Reliance on environment variables for configuration can be problematic if not managed securely.

Safety Score

moderate risk

Positive

+Requires specific Teams application setup and permissions.
+Environment variables are used for configuration, avoiding hardcoded secrets in code.
+Provides read and write capabilities, but no direct execution.
+Security policy is defined for reporting concerns.

Risks

-Write operations can modify Teams channels and messages.
-Improperly configured Teams app or permissions can lead to unauthorized access.
-Exposure of environment variables containing secrets could compromise the server.
-No explicit input validation or sanitization is mentioned, increasing risk of injection attacks.

Use Cases

Collaboration Automation

-Automatically create threads for new incidents.
-Post updates to Teams channels based on external events.
-Summarize key discussion points from Teams threads.

Alerting and Notifications

-Send alerts to Teams channels when critical errors occur.
-Notify users of important deadlines or milestones.
-Forward notifications from other systems to Teams.

Information Retrieval

-Search for specific information within Teams channels.
-List channel members for contact purposes.
-Monitor channel activity for compliance purposes.

Who Is This For?

Best For

Automating communication workflows within Microsoft Teams.
Integrating external systems with Teams channels.
Providing a programmatic interface for managing Teams interactions.
Teams administrators seeking to automate tasks.

Not Ideal For

Applications requiring strict security and isolation.
Use cases involving sensitive data without proper encryption and access controls.
Environments where environment variable management is not secure.
Real-time applications requiring guaranteed low latency.

Autonomy & Execution

Default ModeRead and Write enabled

Autonomy is governed by the permissions granted to the Teams application and the configuration of the server. No built-in sandboxing or rollback mechanisms are provided.

StatelessYes

Retry LogicNot documented

ConcurrencyNot documented

Production Tip

Securely manage and rotate the TEAMS_APP_PASSWORD to prevent unauthorized access.

FAQ

What permissions are required for the Teams application?

The Teams application needs permissions to read and write messages, manage channels, and access team members. Refer to the MS-Teams-setup.md document for details.

How do I secure the TEAMS_APP_PASSWORD?

Store the password securely using a secrets management system or environment variable encryption. Rotate the password regularly.

What happens if the Teams API rate limit is exceeded?

The server may experience errors or delays. Implement caching and throttling to avoid exceeding the rate limit.

Can I use this server with multiple Teams teams?

The configuration uses TEAM_ID, so it is likely configured for a single team. Multi-team support may require code modifications.

How do I monitor the server's performance?

Implement logging and monitoring to track API usage, error rates, and server resource consumption.

Is there support for message formatting (e.g., Markdown) in messages?

The documentation doesn't explicitly mention message formatting. Check the Teams API documentation for supported formats.

How do I handle errors when interacting with the Teams API?

Implement robust error handling to catch exceptions and retry failed requests. Log errors for debugging purposes.
