get_merge_request_diffs
Retrieves the diffs for a merge request
Part of the GitLab MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents call get_merge_request_diffs to retrieve information from GitLab without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions — but you may still want rate limits to control API costs.
WHY ENFORCE A POLICY ON GET_MERGE_REQUEST_DIFFS
Even though get_merge_request_diffs only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
RECOMMENDED POLICY
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

How do I enforce a policy on get_merge_request_diffs?
Add a rule in your Intercept YAML policy under the tools section for get_merge_request_diffs. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the GitLab MCP server.
What risk level is get_merge_request_diffs?

Can I rate-limit get_merge_request_diffs?
Yes. Add a rate_limit block to the get_merge_request_diffs 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 get_merge_request_diffs completely?
Set action: deny in the Intercept policy for get_merge_request_diffs. 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.
