Mcp-worker (GuyMichaely/Mcp-worker) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
Enables ChatGPT to securely control a single authorized Windows worker through an MCP endpoint, handling job scheduling, approval, and execution with outbound-only connectivity.
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.

M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
CHATGPT_MACHINE_MCP_HOMELOCAL_MCP_BEARER_TOKENWINDIRAll four hints declared on every tool
29/32 tools missing one or more hints — machine_status (missing: idempotentHint); policy_explain (missing: idempotentHint); desktop_status (missing: idempotentHint), +26 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.
Destructive tools are labelled
2 tools perform destructive updates without destructiveHint — fs_move deletes at line 289 (fs.rmSync(destination, { recursive: true, force: true })); file_import deletes at line 343 (fs.rmSync(temporary, { force: true }))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
openWorldHint matches behaviour
1 tool claims openWorldHint=false but make outbound HTTP — file_import → dynamic (line 337)
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.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 5/32 tools referenced in tests (16%)
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.
Domain consistency
npm scope @mcp-worker doesn't match GitHub owner guymichaely
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

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.
