AI agents call teams_get_channel to retrieve information from Sage MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves channel information without creating, modifying, or deleting data. It has no side effects and presents minimal risk if misused by an agent—it can only expose existing channel metadata that an authenticated user would already have access to via normal OAuth authentication.
From the tool's definition Tool name and description indicate retrieval only: 'Get details of a specific channel in a team'. The verb 'get' and the absence of any modification language (create, update, delete, send) establish this as a read-only operation.
Documented attack patterns abuse exactly the kind of access teams_get_channel gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for teams_get_channel:
{
"version": "1",
"default": "deny",
"tools": {
"teams_get_channel": {}
}
}teams_get_channel is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get details of a specific channel in a team. It is categorised as a Read tool in the Sage MCP MCP Server, which means it retrieves data without modifying state.
Register the Sage MCP server in PolicyLayer and add a rule for teams_get_channel: 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 Sage MCP. Nothing to install.
teams_get_channel 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 teams_get_channel 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 teams_get_channel. 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.
teams_get_channel is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
