update_pull_request_branch
Update pull request branch
Part of the GitHub MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents use update_pull_request_branch to create or modify resources in GitHub. 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.
WHY ENFORCE A POLICY ON UPDATE_PULL_REQUEST_BRANCH
Without a policy, an AI agent could call update_pull_request_branch 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 GitHub.
RECOMMENDED POLICY
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

How do I enforce a policy on update_pull_request_branch?
Add a rule in your Intercept YAML policy under the tools section for update_pull_request_branch. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the GitHub MCP server.
What risk level is update_pull_request_branch?
update_pull_request_branch is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Can I rate-limit update_pull_request_branch?
Yes. Add a rate_limit block to the update_pull_request_branch 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 update_pull_request_branch completely?
Set action: deny in the Intercept policy for update_pull_request_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.
What MCP server provides update_pull_request_branch?
update_pull_request_branch is provided by the GitHub MCP server (github/github-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
