List workspaces (Cloud) or projects (Server/DC).
AI agents call list_workspaces to retrieve information from MCP Atlassian + Bitbucket without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about workspaces or projects without side effects. It is a pure read operation that returns information already accessible to the authenticated user. No data is created, modified, deleted, or executed. Low severity due to minimal blast radius if misused—an agent could only retrieve organizational structure information.
From the tool's definition Tool name 'list_workspaces' and description 'List workspaces (Cloud) or projects (Server/DC)' indicate a query/retrieval operation with no modification or deletion of data.
Attacks that exploit this kind of access
List workspaces (Cloud) or projects (Server/DC). It is categorised as a Read tool in the MCP Atlassian + Bitbucket MCP Server, which means it retrieves data without modifying state.
Register the MCP Atlassian + Bitbucket MCP server in PolicyLayer and add a rule for 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 MCP Atlassian + Bitbucket. Nothing to install.
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 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 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.
list_workspaces is provided by the MCP Atlassian + Bitbucket MCP server (jellythomas/mcp-atlassian-with-bitbucket). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
