AI agents call read_csharp_symbol to retrieve information from RimSage without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only operations on RimWorld source code, retrieving C# type and method definitions. It has no side effects—it does not modify, execute, or delete code. It is informational and safe for an AI agent to use. The sibling tools (get_def_details, list_directory, read_file, search_defs, search_source) are all similarly read-only, confirming this server's purpose is code browsing only.
From the tool's definition Tool name 'read_csharp_symbol' and description 'Read a C# type or method definition' explicitly indicate retrieval of source code definitions with no modification capabilities.
Documented attack patterns abuse exactly the kind of access read_csharp_symbol gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and RimSage, and nothing reaches the server without passing your rules. This is the rule we recommend for read_csharp_symbol:
{
"version": "1",
"default": "deny",
"tools": {
"read_csharp_symbol": {}
}
}read_csharp_symbol 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.
Read a C# type or method definition. It is categorised as a Read tool in the RimSage MCP Server, which means it retrieves data without modifying state.
Register the RimSage MCP server in PolicyLayer and add a rule for read_csharp_symbol: 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 RimSage. Nothing to install.
read_csharp_symbol 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 read_csharp_symbol 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 read_csharp_symbol. 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.
read_csharp_symbol is provided by the RimSage MCP server (realloon/rimsage). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
