List commits in a Bitbucket repository, optionally for a specific branch/tag/hash
AI agents call bb_list_commits 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 retrieves commit history data from a repository. It performs no modifications, deletions, or executions—it only reads and returns information about existing commits. The optional filtering parameters (branch/tag/hash) are for scoping the query, not for mutating state. This is a standard read operation with minimal risk.
From the tool's definition Tool name contains 'list' and description states 'List commits in a Bitbucket repository', which is a retrieval operation with no side effects.
Attacks that exploit this kind of access
List commits in a Bitbucket repository, optionally for a specific branch/tag/hash. 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_list_commits: 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_list_commits 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_list_commits 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_list_commits. 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_list_commits 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.
