Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Turn Claude into an ISO 27001 compliance assistant — controls, risk register, policies, evidence tracking, SoA generation, and full audit workflows in one local encrypted MCP server.

Why this exists

ISO 27001 compliance work is typically scattered across spreadsheets, Word docs, ticketing systems, and shared drives. Security teams and consultants spend more time chasing evidence and reformatting documents than actually improving security posture.

`iso27001-mcp` solves this by giving Claude a live, stateful ISMS — all 93 ISO 27001:2022 controls seeded and ready, a real risk register, policy and procedure generators, evidence tracking, audit workflows, and a Statement of Applicability, backed by an encrypted local database that never leaves your machine.

Questions

What is the ISO 27001 MCP server?

Model Context Protocol (MCP) server for ISO27001: A stateful Model Context Protocol (MCP) server that gives Claude a complete ISO 27001:2022 Information Security Management System (ISMS). Ask Claude to run gap assessments, manage risks, generate policies, track evidence, and run audits — all backed

What tools does ISO 27001 expose?

52 in total: 29 read-only, 22 that write, and 1 that can delete or overwrite (revoke_api_key). Every one is listed on this page with its risk.

Is ISO 27001 safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does ISO 27001 need?

It reads DB_ENCRYPTION_KEY, HMAC_SECRET and MCP_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does ISO 27001 run?

It speaks sse and stdio, so it runs as a local process your client starts. It is published on npm as iso27001-mcp at 0.9.83.

How current is this page?

The grade is for one exact copy of the source (b53b10c3032a), read on 2026-10-08. The repository is watched and re-audited when it changes.
