Install and manage a self-hosted XNS Relayer — S3-compatible distributed object storage — conversationally over stdio. 15 tools cover prerequisites, account registration, install, claim, health, VPD configuration, S3 verification, CLI credentials, settings, restart, and backups.
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.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Axios Node HTTP adapter can use an inherited proxy after interceptor config cloning
Axios: Excessive recursion in formDataToJSON can cause denial of service
Axios: Nested axios option objects can consume polluted prototype values
Axios: NO_PROXY bypass for 0.0.0.0 local addresses in axios

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
15/15 tools missing one or more hints — check_claim_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); check_email_verified (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); check_prerequisites (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +12 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 inputs are validated
11/15 tool handlers declare input schemas (73%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Production dependencies are patched
0 critical, 1 high severity in production deps — axios@1.16.1 (high), axios@1.16.1 (medium)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

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.
