Medium Risk

CreatePR

Create a new GitHub Pull Request with specified title, body, and branches. Automatically detects GitHub URL and current branch from local git configuration.

Part of the Code Review MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

code-review-mcp-server Write Risk 2/5

AI agents use CreatePR to create or modify resources in Code Review. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call CreatePR repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Code Review.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the CreatePR tool do? +

Create a new GitHub Pull Request with specified title, body, and branches. Automatically detects GitHub URL and current branch from local git configuration.. It is categorised as a Write tool in the Code Review MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on CreatePR? +

Add a rule in your Intercept YAML policy under the tools section for CreatePR. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Code Review MCP server.

What risk level is CreatePR? +

CreatePR is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit CreatePR? +

Yes. Add a rate_limit block to the CreatePR rule in your Intercept 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.

How do I block CreatePR completely? +

Set action: deny in the Intercept policy for CreatePR. 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.

What MCP server provides CreatePR? +

CreatePR is provided by the Code Review MCP server (code-review-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
