Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 58 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name harvest-mcp.

  • Pass
    Lists tools

    tools/list returned 20 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 58 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 58 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    77 of 77 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-11-10T23:33:26.029301Z, within 180 days.

Capabilities

Tools 20

harvest_create_time_entry

Create a time entry. Requires project_id, task_id and spent_date. Provide `hours` to log a specific duration; OR provide `started_time` (+ optional `ended_time`) for a timestamped entry; OR omit both to start a running timer (on a timestamp-tracking account). Use harvest_list_project_assignments to find valid project_id + task_id. Harvest REST: POST /time_entries. WRITE — creates data.

Discovered
harvest_delete_time_entry

Permanently delete a time entry by id. This cannot be undone. Harvest REST: DELETE /time_entries/{id}. WRITE — destroys data.

Discovered
harvest_get_client

Retrieve a single client by id. Harvest REST: GET /clients/{id}.

Discovered
harvest_get_company

Retrieve the company/account settings for the authenticated account (name, currency, time/date formats, week start, feature flags). Harvest REST: GET /company.

Discovered
harvest_get_current_user

Retrieve the currently authenticated user (whom the access token belongs to). Harvest REST: GET /users/me.

Discovered
harvest_list_projects

List projects, optionally filtered by active status or client, or updated-since. Paginated. Harvest REST: GET /projects.
