Enables natural language management of 20i web hosting services, including domains, databases, email, WordPress, and more, through AI assistants like Claude and ChatGPT.
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.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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
302/302 tools missing one or more hints — get_reseller_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_account_balance (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_domains (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +299 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 3/302 tools referenced in tests (1%)
Write tests that reference each tool by name so every tool has at least one test.
Secrets stay with their owner
1 secret sent to a request target we could not resolve (TWENTYI_API_KEY → dynamic) — often a configured endpoint, not necessarily third-party
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
Secrets never reach shell commands
1 secret value passed to a subprocess as an argument — no shell is invoked, so there is nothing to inject into
Never pass secrets through shell commands. Use library APIs that accept credentials as arguments.
Secrets not logged
26 secret values sent to log
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 14 high severity in production deps — @modelcontextprotocol/sdk@0.5.0 (high), adm-zip@0.5.16 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
5 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
