commit_backup · Kontexta MCP: Risk & Policy

WHAT IT DOES

What commit_backup does on Kontexta

AI agents invoke commit_backup to trigger actions in Kontexta. 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 commit_backup needs a policy

The tool performs a git commit/backup and syncs over the network. It is side-effectful (modifies repository state and communicates externally), but is not purely destructive or financial. It spans Write and Execute categories; since it triggers an external network operation (push/sync), Execute is the most appropriate category.

Verdict

commit_backup Rate-limited

commit_backup 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.

SIDE-EFFECTFUL — TOUCHES THE NETWORK. Sync the project. It is categorised as a Execute tool in the Kontexta MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on commit_backup? +

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

What risk level is commit_backup? +

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

Can I rate-limit commit_backup? +

Yes. Add a rate_limit block to the commit_backup 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 commit_backup completely? +
