List all workspaces accessible by the current user.
AI agents call list_workspaces to retrieve information from Bitbucket 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 information about workspaces without modifying, deleting, executing code, or moving money. It is a straightforward data retrieval operation, consistent with Read category tools like 'list' and 'get'. The severity is low because listing accessible workspaces is informational and carries minimal risk of harm even if misused by an AI agent.
From the tool's definition Tool name is 'list_workspaces' and description states it 'List all workspaces accessible by the current user' — a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all workspaces accessible by the current user. It is categorised as a Read tool in the Bitbucket MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Bitbucket MCP Server 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 Bitbucket MCP Server. 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 Bitbucket MCP Server MCP server (korfu/mcp-bitbucket). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_workspaces is one line of Bitbucket MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
