backgen-mcp
BackGen's MCP server lets AI assistants scaffold production-ready Express.js + TypeScript backend projects with your choice of ORM (Prisma, Drizzle, Mongoose), install auth/payment/storage plugins, generate CRUD resources, and run health checks — all through natural language conversation.
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.
Handlebars.js has JavaScript Injection via AST Type Confusion
Handlebars.js has JavaScript Injection via AST Type Confusion by tampering @partial-block

Handlebars.js has JavaScript Injection in CLI Precompiler via Unescaped Names and Options
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
10/10 tools missing one or more hints — add_plugin (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); doctor (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); generate_factory (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +7 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
Only 0/10 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
8/10 tool handlers wrap calls in try/catch (80%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
7/10 tools referenced in tests (70%)
Write tests that reference each tool by name so every tool has at least one test.
Tests pass
npm test failed — tests do not pass
Make sure npm test runs cleanly. Common cause: missing build step or missing env vars.
Production dependencies are patched
1 critical, 4 high severity in production deps — handlebars@4.7.8 (critical), handlebars@4.7.8 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
