git_push · PSKit MCP: Risk & Policy

WHAT IT DOES

What git_push does on PSKit

AI agents invoke git_push to trigger actions in PSKit. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why git_push needs a policy

git_push triggers an external operation (pushing commits to a remote repository) that modifies remote state. While it can be partially undone (force-reverting), it exposes code to external systems, can overwrite remote branches, and triggers CI/CD pipelines or webhooks. This qualifies as Execute with high severity since misuse could expose sensitive code, break shared branches, or trigger unintended deployments.

Verdict

git_push Rate-limited

git_push stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches PSKit, so you can run agents against it safely.

FAQ

Questions about git_push

What does the git_push tool do? +

Push the current branch to a remote. It is categorised as a Execute tool in the PSKit MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on git_push? +

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

What risk level is git_push? +

git_push is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit git_push? +

Yes. Add a rate_limit block to the git_push 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.

How do I block git_push completely? +

Set action: deny in the PolicyLayer policy for git_push. 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 git_push? +

git_push is provided by the PSKit MCP server (nickalus12/pskit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
