Releases: gabrielion/OPNSenseMCP
Release list
v0.1.1
Patch release of @gabrielion/opnsense-mcp — ask your firewall questions in plain language, from
Claude Code, Codex or OpenCode. Still a preview: read-only by default, with one experimental,
confirmation-gated alias mutation.
Fixed since 0.1.0
- Service listing against a real OPNsense no longer fails intermittently on large pages: the
server now accepts OPNsense's clampedrowCountecho instead of rejecting the page. --helpand--versionnow answer usefully; previously any argument other thanconfigure
printed a bareError.npx -y @gabrielion/opnsense-mcp --versionis now the documented
install check.- The README's
claude mcp addone-liner was corrected (the previous flag order fails on current
Claude Code versions).
Under the hood
- Groundwork for durable mutation state (a hardened, concurrency-proven private state-root module)
ships in this build but is not yet wired to any tool — writes keep their current
process-lifetime backup and audit semantics, documented in the README. - CI now enforces the sealed packaged-server evidence on every push and on the release path.
Getting started
npx -y @gabrielion/opnsense-mcp configureThen connect your assistant — see the Quickstart.

v0.1.0
First published release of @gabrielion/opnsense-mcp — ask your firewall questions in plain
language, from Claude Code, Codex or OpenCode.
This is a preview: a small MCP server that lets an assistant inspect an OPNsense system, and —
only when explicitly enabled — create or delete one kind of firewall alias behind a confirmation,
backup and audit envelope.

What it exposes
Four read-only tools — server_status, opn_describe, opn_get, opn_list — plus three prompts
that only produce a read-only preparation plan and execute nothing.
READ_ONLY=true is the default, and under it no write tool is listed or dispatchable. The two
experimental write tools additionally require a feature flag and an explicit ALLOWED_RESOURCES
scope, so nothing becomes writable by accident.
Credentials are read from a stored configuration: nothing is echoed and nothing is passed as a
process argument.
Evidence
The claims above are tested rather than asserted:
- Live VM attestation — the read surface and the bounded alias lifecycle (list, create, read
back, delete, prove absence) run against a disposable, SHA-256-pinned official OPNsense 26.7
image, with no operator credential. The attestation is bound to the released commit and
re-verified by CI:
docs/evidence/product3-vm.json. - Protocol conformance scenarios for MCP
2025-11-25and2026-07-28. These are targeted
interoperability scenarios, not a claim of complete protocol conformance. - Compatibility floor built and tested on Node.js 22.19.0.
Windows is a required product target but is not yet claimed: macOS and Linux are the verified hosts.
