An MCP server providing a ZX Spectrum emulator for AI testing, enabling loading and running of Spectrum software with debugging, display, and audio features.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. 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.

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
52/52 tools missing one or more hints — breakpoint (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); delete_breakpoint (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); port_watchpoint (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +49 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
48/52 tool handlers declare input schemas (92%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
29/52 tools referenced in tests (56%)
Write tests that reference each tool by name so every tool has at least one test.
Dev dependencies
3 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Tool description accuracy
screenshot: description implies read-only but handler writes/deletes/executes; stop_trace: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
