✅
11 tools verified — handlers match their declared behaviour
7 read-only tools verified — handlers contain no write/delete/exec
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README

// tools this server exposes11 tools

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.

get_me

Get the authenticated Harvest user (name, email, id, roles, timezone). Useful to resolve 'my' time entries and check the connection.

list_clients

List clients in the Harvest account. Returns id, name, active state.

list_projects

List projects with their client, code, and budget info. Filter by client_id or include archived projects.

list_project_tasks

List the task assignments for a project (task_id + name). You need a task_id to log time or start a timer on that project.

list_time_entries

List time entries, newest first. Filter by date range (from/to, YYYY-MM-DD), project_id, user_id, or only_running. Use mine=true to limit to the authenticated user. Returns up to 300 entries per call.

get_time_report

Aggregated hours for a date range, grouped by clients, projects, tasks, or team members. Includes billable vs total hours and billable amounts (when permitted). Perfect for 'how many hours did we spend on X this month?'

log_time

Create a completed time entry: project, task, date, and duration in hours (e.g. 1.5). Use list_projects and list_project_tasks first to get ids. Add a short note describing the work.

start_timer

Start a running timer on a project + task for today (authenticated user). Any other running timer for the user is stopped automatically by Harvest. Use list_project_tasks to get the task_id.

stop_timer

Stop a running timer. If time_entry_id is omitted, finds and stops the authenticated user's currently running timer.

update_time_entry

Edit an existing time entry's hours, notes, date, project, or task. Only provided fields are changed. (This server intentionally has no delete tool — set hours or move entries instead, and delete in Harvest itself if truly needed.)

list_users

List users in the Harvest account (id, name, email, roles). Needed for per-person filters and team reports. Requires admin/manager access.

All four hints declared on every tool

11/11 tools missing one or more hints — get_me (missing: destructiveHint, idempotentHint, openWorldHint); list_clients (missing: destructiveHint, idempotentHint, openWorldHint); list_projects (missing: destructiveHint, idempotentHint, openWorldHint), +8 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

10/11 tool handlers declare input schemas (91%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
