Get details of a specific branch including its latest commit.
AI agents call get_branch 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 retrieves information about a branch and its commit history. It performs a read-only query operation with no ability to modify, delete, or execute code. The blast radius of misuse is minimal—an attacker could gather repository intelligence but cannot alter code, trigger pipelines, or cause destructive changes. Classified as Read with low severity.
From the tool's definition Tool name 'get_branch' and description 'Get details of a specific branch including its latest commit' indicate retrieval of branch metadata without modification or side effects.
Attacks that exploit this kind of access
Get details of a specific branch including its latest commit. 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 get_branch: 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.
get_branch 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 get_branch 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 get_branch. 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.
get_branch is provided by the Bitbucket Cloud MCP Server MCP server (lexmata/bitbucket-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
