Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
FLINT_MCP_SECRETyour URL can render charts on your account. Set and the URL becomes theFLINT_PUBLIC_HOSTPORTTool 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
2/2 tools missing one or more hints — compile_chart (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_chart_types (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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
1/2 tool handlers declare input schemas (50%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Shell command execution
2 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Readable source code
2 files appear obfuscated
Ship unminified, readable source.

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.
