AI agents call get_code to retrieve information from Codevira MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves source code content without side effects. It performs a read-only query operation to fetch a function or class definition, analogous to searching or fetching data. There is no code execution, data modification, deletion, or financial impact possible from this action.
From the tool's definition Tool name 'get_code' and description 'Get the full source of a single function or class by name' indicate retrieval of existing code without modification or execution.
Documented attack patterns abuse exactly the kind of access get_code gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Codevira MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_code:
{
"version": "1",
"default": "deny",
"tools": {
"get_code": {}
}
}get_code is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get the full source of a single function or class by name. It is categorised as a Read tool in the Codevira MCP MCP Server, which means it retrieves data without modifying state.
Register the Codevira MCP server in PolicyLayer and add a rule for get_code: 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 Codevira MCP. Nothing to install.
get_code is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_code 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 get_code. 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.
get_code is provided by the Codevira MCP server (sachinshelke/codevira). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Codevira MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
