WHAT IT DOES

What saveCodebase does on Codebase MCP

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

RISK

Why saveCodebase is rated Medium

This tool creates or modifies files by writing codebase data to disk. This is a reversible Write operation—the file can be deleted or overwritten. It does not execute code, delete data irreversibly, or move money.

From the tool's definition Tool name 'saveCodebase' and description 'Save the codebase to a file' indicate file creation/modification. The tool writes codebase content to a file using RepoMix.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs saveCodebase safely

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

saveCodebase Rate-limited

saveCodebase 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.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Codebase MCP, apply this rule, and every saveCodebase call is checked against it from then on.
