WHAT IT DOES

What merge does on Lint

AI agents use merge to create or update resources in Lint, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Lint environment.

RISK

Why merge is rated Medium

The merge operation modifies the current branch by integrating changes from another branch. This is a write operation because it creates new commit history and alters the repository state.

From the tool's definition Tool description states it 'Merges a branch into the current branch' and 'Returns structured data with merge status, fast-forward detection, conflicts, and commit hash.' This is a reversible modification of version control state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs merge safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Lint, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For merge, this is the rule to start with:

merge Rate-limited

merge stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about merge

What does the merge tool do? +

Merges a branch into the current branch. Supports abort, continue, and quit actions. Returns structured data with merge status, fast-forward detection, conflicts, and commit hash. It is categorised as a Write tool in the Lint MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on merge? +

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

What risk level is merge? +

merge is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit merge? +

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

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

merge is provided by the Lint MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
