AI agents call get_task_git_refs to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about git references (branches and pull requests) associated with a task. It performs a read-only query operation with no side effects, no code execution, no data modification, and no destructive actions. The action is purely informational lookup.
From the tool's definition Tool name 'get_task_git_refs' and description 'Get branches and pull requests linked to a task' indicate retrieval of existing data without modification or execution of code.

Register the Todos MCP server in PolicyLayer and add a rule for get_task_git_refs: 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 Todos. Nothing to install.
get_task_git_refs 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 get_task_git_refs 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 get_task_git_refs. 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.
