MCP pfsense: MCP server, setup and security

What MCP pfsense does

According to its repository: “Manage pfSense firewalls: rules, DHCP leases, DNS overrides, gateway monitoring, ARP table and services, with two-step confirmation for destructive actions.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. MCP pfsense is listed under Cloud platforms, a category of 116 servers in the directory, where it ranks #93 by stars.

Installing and connecting MCP pfsense

Distribution modes declared in the official MCP registry:

• PyPI package (Python, started with uvx or pip)

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: Python.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to MCP pfsense. That does not replace reading the code.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on March 10, 2026, the antonio-mello-ai/mcp-pfsense repository has 6 stars and 3 forks, with 4 open issues. It has more stars than 17% of the servers in the directory. Last change 1 month ago. Version published in the registry: 0.2.0 (August 17, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
