A local-first MCP server for creating and managing App Store and Google Play screenshot decks, letting agents upload, review, localize, and export store-ready images without accessing source code.
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.

APPMARQUEE_CLAUDE_DESKTOP_CONFIGAPPMARQUEE_INSTALL_DRY_RUNAPPMARQUEE_URLAll four hints declared on every tool
7/10 tools missing one or more hints — appmarquee_status (missing: destructiveHint, idempotentHint); appmarquee_list_projects (missing: destructiveHint, idempotentHint); appmarquee_get_project (missing: destructiveHint, idempotentHint), +4 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.
openWorldHint matches behaviour
9 tools claim openWorldHint=false but make outbound HTTP — appmarquee_status → dynamic (line 41); appmarquee_list_projects → dynamic (line 41); appmarquee_create_project → dynamic (line 41)
Either flip openWorldHint to true (acknowledging external reach) or refactor the handler to avoid outbound HTTP. If the only network calls are to a known fixed endpoint that you consider part of the tool itself, document that and keep openWorldHint=false; otherwise true is honest.
Tool inputs are validated
Only 4/10 tool handlers declare input schemas (40%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
9/10 tool handlers wrap calls in try/catch (90%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 0/10 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
2 critical, 11 high severity in production deps — next@15.0.3 (critical), next@15.0.3 (critical)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
2/25 production deps stale: tailwindcss-animate@2023-08-28 (2.9y), @dnd-kit/utilities@2023-11-06 (2.7y)

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.
