WHAT IT DOES

What getCodebase does on Codebase MCP

AI agents call getCodebase to retrieve information from Codebase MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why getCodebase is rated Low

This tool retrieves and outputs codebase contents for analysis without modifying, executing, or deleting anything. It is a read-only operation that gathers information from an existing codebase. The blast radius of misuse is minimal — an agent could at most learn information already present in the repository, with no capability to alter state or trigger external actions.

From the tool's definition Tool description: 'Retrieve the entire codebase as a single text output using RepoMix' — the verb 'retrieve' and the passive nature of the operation indicate data fetching with no side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs getCodebase 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 getCodebase, this is the rule to start with:

getCodebase Allowed

getCodebase is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "getCodebase": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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