Get Julia documentation for a package, module, type, function, or method
AI agents call get-doc to retrieve information from Julia Documentation MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves documentation metadata about Julia packages, modules, types, functions, and methods. It performs no write, execute, destructive, or financial operations. The documentation itself is static reference material. The blast radius of misuse is negligible—an attacker cannot cause harm by requesting documentation repeatedly or for unintended subjects.
From the tool's definition Tool description states 'Get Julia documentation' - a retrieval operation with no modification capability. The action verb 'Get' combined with 'documentation' indicates querying/fetching read-only information.
Documented attack patterns abuse exactly the kind of access get-doc gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Julia Documentation MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get-doc:
{
"version": "1",
"default": "deny",
"tools": {
"get-doc": {}
}
}get-doc is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get Julia documentation for a package, module, type, function, or method. It is categorised as a Read tool in the Julia Documentation MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Julia Documentation MCP Server MCP server in PolicyLayer and add a rule for get-doc: 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 Julia Documentation MCP Server. Nothing to install.
get-doc 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-doc 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-doc. 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-doc is provided by the Julia Documentation MCP Server MCP server (jonathanfischer97/juliadoc-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Julia Documentation MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
