Create a new pull request in a Bitbucket repository
AI agents use bitbucket_create_pull_request to create or update resources in Sage MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sage MCP environment.
This tool creates a new pull request, which is a reversible modification to a repository's state. It does not execute arbitrary code, delete data irreversibly, or move money. It falls squarely into the Write category.
From the tool's definition Tool name is 'bitbucket_create_pull_request' and description states 'Create a new pull request in a Bitbucket repository'. The verb 'Create' and 'new' indicate data creation that is reversible (pull requests can be closed/deleted).
Documented attack patterns abuse exactly the kind of access bitbucket_create_pull_request gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for bitbucket_create_pull_request:
{
"version": "1",
"default": "deny",
"tools": {
"bitbucket_create_pull_request": {
"limits": [
{
"counter": "bitbucket_create_pull_request_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}bitbucket_create_pull_request stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a new pull request in a Bitbucket repository. It is categorised as a Write tool in the Sage MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sage MCP server in PolicyLayer and add a rule for bitbucket_create_pull_request: 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 Sage MCP. Nothing to install.
bitbucket_create_pull_request is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the bitbucket_create_pull_request 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 bitbucket_create_pull_request. 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.
bitbucket_create_pull_request is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
