find_user
AI agents call find_user to retrieve information from Bitbucket Server MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
User lookup is a non-destructive query that retrieves information about users without modifying or executing anything. Even if exposed to an AI agent, discovering user identities poses minimal risk compared to other categories. The low confidence reflects the empty description, but the tool name strongly implies read-only behavior.
From the tool's definition Tool name 'find_user' indicates a user lookup/search operation. No description provided, but the name pattern and context within a Bitbucket Server MCP with other read operations (browse_files, can_merge_pull_request) suggest data retrieval.
Attacks that exploit this kind of access
find_user. It is categorised as a Read tool in the Bitbucket Server MCP MCP Server, which means it retrieves data without modifying state.
Register the Bitbucket Server MCP server in PolicyLayer and add a rule for find_user: 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 Server MCP. Nothing to install.
find_user 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 find_user 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 find_user. 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.
find_user is provided by the Bitbucket Server MCP server (manpreetshuann/bitbucket-server-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
