AI agents call get_skill 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 queries or retrieves skill information from the knowledge base without creating, modifying, deleting, or executing any operations. It has no side effects beyond returning data to the caller, making it a Read operation with minimal risk.
From the tool's definition Tool is described as a 'search over active skills' — a retrieval operation with no modification, deletion, or execution of external commands. The verb 'get' and 'search' both indicate data retrieval.
Documented attack patterns abuse exactly the kind of access get_skill 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_skill:
{
"version": "1",
"default": "deny",
"tools": {
"get_skill": {}
}
}get_skill 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.
v3.1.0 M3: Composite-ranked search over active skills. 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_skill: 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_skill 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_skill 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_skill. 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_skill 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.
