List commits in a repository
AI agents call list_commits 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.
The tool retrieves or lists existing commits, which is a read-only operation with no side effects. It does not create, modify, or delete commits, nor does it execute code or trigger external operations. This is consistent with the Read category for tools that query or retrieve data.
From the tool's definition Tool name is 'list_commits' and description states 'List commits in a repository' — this is a query operation that retrieves commit history without modifying any data.
Attacks that exploit this kind of access
List commits in a repository. 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 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 MCP Server. Nothing to install.
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 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 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.
list_commits is provided by the Bitbucket MCP Server MCP server (jlromano/bitbucket-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
