What add_allowed_command does on Code MCP Server
AI agents use add_allowed_command to create or update resources in Code MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Code MCP Server environment.
Why add_allowed_command is rated Medium
This tool creates or modifies project-level command configurations, which is a reversible write operation. It doesn't execute commands (Execute), doesn't delete data (Destructive), and doesn't handle financial transactions.
From the tool's definition Tool name 'add_allowed_command' and description 'Add a command to the project' indicate creation/modification of project configuration, specifically allowlisting commands for execution within the project context.
Attacks that exploit this kind of access
The rule that runs add_allowed_command safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Code MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_allowed_command, this is the rule to start with:
add_allowed_command 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Code MCP Server, apply this rule, and every add_allowed_command call is checked against it from then on.
Questions about add_allowed_command
Add a command to the project\. It is categorised as a Write tool in the Code MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Code MCP Server MCP server in PolicyLayer and add a rule for add_allowed_command: 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 Code MCP Server. Nothing to install.
add_allowed_command is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the add_allowed_command 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.
Set action: deny in the PolicyLayer policy for add_allowed_command. 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.
add_allowed_command is provided by the Code MCP Server MCP server (agentics-ai/code-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
