AI agents call get_teams to retrieve information from Mattermost MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns team membership information for the authenticated user. It performs data retrieval only, with no capability to create, modify, delete, or execute operations. The blast radius of misuse is minimal—an attacker could only learn which teams a user is a member of, which is typically non-sensitive metadata in collaboration platforms. This is a straightforward Read operation.
From the tool's definition Tool name 'get_teams' and description '현재 사용자가 속한 모든 팀 목록을 가져옵니다' (retrieves a list of all teams the current user belongs to) indicate a retrieval operation with no side effects.

Register the Mattermost MCP Server MCP server in PolicyLayer and add a rule for get_teams: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mattermost MCP Server. Nothing to install.
get_teams is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_teams rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_teams. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_teams is provided by the Mattermost MCP Server MCP server (jhanglim/mattermost-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
