MCP server for ModSecurity WAF management — monitor, analyze, and configure OWASP CRS via AI assistants
MCP server for ModSecurity WAF management — monitor, analyze, and configure OWASP CRS via AI assistants. That is what the waf mcp mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
An MCP (Model Context Protocol) server for managing OWASP ModSecurity CRS via Docker. Gives AI assistants like Claude direct access to WAF monitoring, analysis, and configuration through a structured drill-down pipeline.
The server publishes 1 tool. What each one is for:
Actions — The Actions tool exposed by this serverConfiguration is passed through the environment: WAF_COMPOSE_DIR, WAF_DOMAIN, IPINFO_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
SecAuditLogFormat JSON)npm on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Waf MCP's toolset — Actions — is a fair guide to whether it matches your workflow. It is maintained by kratosuae; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
