Harnios MCP

Harnios is a self-hosted, MCP-based storage system that gives every AI assistant you use — Claude, ChatGPT, Cursor, or anything else — a shared, persistent memory of your business: knowledge base, skills, projects, operational tables, and reports, all in one place. Connect a new tool once, and it reads and writes through the same store instead of starting from zero.

Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

🚨
Known vulnerabilities in dependencies: 2 critical, 5 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

21/21 tools missing one or more hints — create_file (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); read_file (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); delete_file (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +18 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool test coverage

Only 2/21 tools referenced in tests (10%)

Write tests that reference each tool by name so every tool has at least one test.

Production dependencies are patched

2 critical, 5 high severity in production deps — next@16.2.10 (critical), next@16.2.10 (critical)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
