Get the currently authenticated Bitbucket user
AI agents call bb_whoami to retrieve information from Bitbucket Cloud 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 the currently authenticated user without modifying, executing, or deleting any data. It is a simple identity lookup operation, semantically equivalent to 'whoami' in Unix systems, which retrieves user context.
From the tool's definition Tool name 'bb_whoami' and description 'Get the currently authenticated Bitbucket user' indicate data retrieval with no side effects.
Attacks that exploit this kind of access
Get the currently authenticated Bitbucket user. It is categorised as a Read tool in the Bitbucket Cloud MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Bitbucket Cloud MCP Server MCP server in PolicyLayer and add a rule for bb_whoami: 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 Cloud MCP Server. Nothing to install.
bb_whoami 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 bb_whoami 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 bb_whoami. 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.
bb_whoami is provided by the Bitbucket Cloud MCP Server MCP server (or2ooo/bitbucket-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
