remark-mcp
Enables AI assistants to browse and read documents from a reMarkable tablet connected via USB, rendering PDF pages as images for the AI to see.
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.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
list_rootList all files and folders in the root of the reMarkable tablet.
list_folderList the contents of a folder on the reMarkable tablet by its ID.
download_pdfDownload a document from the reMarkable tablet as a PDF, returned as base64-encoded data.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

RM_MCP_LOG"": "info",RM_MCP_LOG_FILE"": "/absolute/path/to/remark-mcp/rm-mcp.log"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
3/3 tools missing one or more hints — list_root (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_folder (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); download_pdf (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.
Descriptions match behaviour
2 tools describe read intent but their handlers mutate — list_root (line 48: fs.appendFileSync(logFile, line)); list_folder (line 48: fs.appendFileSync(logFile, line))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
2/3 tool handlers declare input schemas (67%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Production dependencies are patched
0 critical, 1 high severity in production deps — axios@1.16.0 (high), axios@1.16.0 (medium)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Tool description accuracy
list_root: description implies read-only but handler writes/deletes/executes; list_folder: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
