Provide practical Structured Text and CODESYS design guidance for writing or improving code, choosing a POU structure, or following CODESYS style.
AI agents call codesys_writing_guidance to retrieve information from CODESYS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure advisory/informational tool that returns curated coding best practices and design recommendations in response to queries. It retrieves or synthesizes guidance (a form of information retrieval) with no ability to execute Structured Text code, modify CODESYS projects, delete resources, or trigger real-world effects on devices or systems. The output is read-only reference material.
From the tool's definition Tool provides 'guidance' and 'assistance' for 'writing or improving code' and 'choosing POU structure'. It offers information and recommendations without executing code, modifying systems, or triggering external operations.
Attacks that exploit this kind of access
Provide practical Structured Text and CODESYS design guidance for writing or improving code, choosing a POU structure, or following CODESYS style. It is categorised as a Read tool in the CODESYS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CODESYS MCP Server MCP server in PolicyLayer and add a rule for codesys_writing_guidance: 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 CODESYS MCP Server. Nothing to install.
codesys_writing_guidance 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 codesys_writing_guidance 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 codesys_writing_guidance. 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.
codesys_writing_guidance is provided by the CODESYS MCP Server MCP server (zandiexoder/codesys-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
