List workspaces the authenticated user belongs to
AI agents call bitbucket_list_workspaces 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.
The tool performs a read-only enumeration of workspaces accessible to the authenticated user. It returns information about workspace membership but does not create, modify, delete, or execute any actions. This is a standard informational query with minimal blast radius if misused by an agent.
From the tool's definition Tool name and description: 'List workspaces the authenticated user belongs to' — this retrieves/queries workspace membership data with no modification, deletion, or execution of operations.
Documented attack patterns abuse exactly the kind of access bitbucket_list_workspaces 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 bitbucket_list_workspaces:
{
"version": "1",
"default": "deny",
"tools": {
"bitbucket_list_workspaces": {}
}
}bitbucket_list_workspaces is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List workspaces the authenticated user belongs to. 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 bitbucket_list_workspaces: 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.
bitbucket_list_workspaces 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 bitbucket_list_workspaces 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 bitbucket_list_workspaces. 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.
bitbucket_list_workspaces 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.
