OT security standards: IEC 62443, NIST 800-82/53, MITRE ATT&CK for ICS
The publisher's own server: Ansvar: Dutch Law
Overview
A local MCP server that gives an assistant reference material on OT/ICS security standards: IEC 62443, NIST 800-82/53 and MITRE ATT&CK for ICS.
- What you can do
- Provides access to OT security standards content covering IEC 62443, NIST 800-82 and NIST 800-53, and MITRE ATT&CK for ICS, so an assistant can look up and discuss industrial control system security guidance. No individual tools are documented in the supplied material, so the exact operations are not confirmed.
- When to use it
- Useful when working on industrial control system or operational technology security questions and you want an assistant to draw on recognized standards and threat frameworks rather than general knowledge.
- Requirements
- Runs as a local process on the user's machine via the npm package @ansvar/ot-security-mcp over stdio. Desktop client only; no authentication, environment variables or headers are declared.
Installation
In SourceWeft
- Open Ot Security Mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
