omnifocus-sync-mcp
A headless MCP server that reads and writes OmniFocus data by directly communicating with the Omni Sync Server via WebDAV, enabling task management without a local OmniFocus app.
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.
of_syncReload the OmniFocus database from the Omni Sync Server. Returns counts of tasks, projects, and tags.
of_list_tasksList tasks with optional filtering. filter: remaining (default), available, flagged, inbox, due_soon, all.
of_get_taskGet a single task by its id, with full detail.
of_list_projectsList all projects with their folder path and status.
of_add_taskCreate a task. Without a project it goes to the inbox. Dates accept ISO 8601 strings.
of_complete_taskMark a task complete (optionally at a specific ISO 8601 time).
of_edit_taskEdit fields of a task. Use clearDue/clearDefer to remove a date. Only provided fields change.
of_delete_taskPermanently delete a task by id (writes an op=delete transaction).
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
fast-xml-parser has an entity encoding bypass via regex injection in DOCTYPE entity names
fast-xml-parser affected by numeric entity expansion bypassing all entity expansion limits (incomplete fix for CVE-2026-26278)
fast-xml-parser affected by DoS through entity expansion in DOCTYPE (no expansion limit)
fast-xml-parser has stack overflow in XMLBuilder with preserveOrder
fast-xml-parser XMLBuilder: XML Comment and CDATA Injection via Unescaped Delimiters

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
8/8 tools missing one or more hints — of_sync (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); of_list_tasks (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); of_get_task (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 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
7/8 tool handlers declare input schemas (88%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
Only 0/8 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
3 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
1 critical, 2 high severity in production deps — fast-xml-parser@4.5.0 (critical), fast-xml-parser@4.5.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
