What read_shader does on Godot
AI agents call read_shader to retrieve information from Godot without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
path | string | Yes | Shader file path |
Parameters from the server's own tool schema.
Why read_shader is rated Low
This tool retrieves shader file contents without modifying, executing, or deleting data. It is a straightforward read operation that fits the Read category with low severity since accessing shader files poses minimal risk.
From the tool's definition Tool name 'read_shader' and description 'Read the contents of a shader file' explicitly indicate data retrieval with no modification or side effects.
Risk signalsAccepts file system path (path)

The rule that runs read_shader safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For read_shader, this is the rule to start with:
read_shader is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every read_shader call is checked against it from then on.
Questions about read_shader
Read the contents of a shader file. It is categorised as a Read tool in the Godot MCP Server, which means it retrieves data without modifying state.
read_shader accepts 1 parameter: path. Required: path. The full parameter table on this page comes from the server's own tool schema.
Register the Godot MCP server in PolicyLayer and add a rule for read_shader: 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 Godot. Nothing to install.
read_shader 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_shader 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_shader. 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_shader is provided by the Godot MCP server (@keeveeg/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
