Get detailed information about a branch including associated pull requests
AI agents call get_branch 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 retrieves and queries data about a branch without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal risk if misused by an AI agent—worst case would be information disclosure of already-accessible repository data.
From the tool's definition Tool name 'get_branch' and description 'Get detailed information about a branch' clearly indicate a retrieval operation with no modification or destructive capability. Returns branch metadata and associated pull request information.
Attacks that exploit this kind of access
Get detailed information about a branch including associated pull requests. 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 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 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 MCP Server MCP server (zhanglc/bitbucket-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
