clockify-python-115

clockify-python-115 is an independent community project. It is not affiliated with, endorsed by, or sponsored by CAKE.com or Clockify. The project uses the Clockify name only to identify the service that it supports.

The distribution contains:

• clockify: a typed async SDK with all 168 known Clockify operations on 29 resources.
• clockify_mcp: a full-featured Model Context Protocol (MCP) server with a sealed approval gate for guarded writes.

Documentation version: 0.2.0. The distribution is available from public PyPI. The default MCP server registers 186 tools: 60 raw reads, 104 guarded or routine writes, 18 workflows, and 4 orientation tools. Set CLOCKIFY_MCP_READ_ONLY=true for the structurally read-only 65-tool build.

Install

Install the SDK or the SDK with the optional MCP server:

uv add clockify-python-115
uv add "clockify-python-115[mcp]"

Python 3.11, 3.12, 3.13, and 3.14 are supported and tested.

SDK quickstart

import asyncio
import os

from clockify import ClockifyClient


async def main() -> None:
    async with ClockifyClient(
        api_key=os.environ["CLOCKIFY_API_KEY"],
        workspace_id=os.environ.get("CLOCKIFY_WORKSPACE_ID"),
    ) as clockify:
        me = await clockify.users.me()
        projects = await clockify.projects.list(archived=False, page_size=25)
        print(me.name, len(projects))


asyncio.run(main())

See docs/quickstart.md and examples/sdk_list_projects.py.

MCP quickstart

clockify-mcp                    # stdio (default)
clockify-mcp --http --port 8000 # Streamable HTTP, stateful sessions

Configure exactly one of CLOCKIFY_API_KEY or CLOCKIFY_ADDON_TOKEN. You can also configure CLOCKIFY_WORKSPACE_ID.

The MCP contract is exact:

• 60 raw read tools and 104 raw write tools;
• 18 workflows (5 read, 7 routine write, 6 gated write) and 4 orientation tools: 186 tools in total;
• routine writes (personal time entries, daily tracking) execute directly and are never retried;
• every other write is guarded: the user approves a deterministic preview of the exact request before anything is sent, bound by a single-use confirmation;
• CLOCKIFY_MCP_READ_ONLY=true serves the read-only build (65 tools, zero writes, structurally unable to mutate).

See docs/mcp.md and examples/mcp_config.example.json.

SDK behavior

• Configure exactly one credential. The SDK rejects caller-supplied authority and Clockify credential headers before network access.
• Ordinary caller headers and X-Request-Id are preserved.
• Read retries support delay-seconds and HTTP-date Retry-After values.
• No write is automatically retried. An ambiguous write transport failure raises MutationOutcomeUnknownError. Read state before a manual retry.
• Pagination names vary by operation. Use iter_pages or iter_all and honor the operation's Last-Page behavior.
• Reports and audit-log operations use their required service hosts automatically.
• Some PUT operations replace the complete entity. Resend each field that must remain. See docs/api-deviations.md.
• API errors expose bounded sanitized detail, status, operation ID, request ID, safe API code, and safe retry timing.

The direct write example is intentionally separate. It mutates only a verified sacrificial workspace and uses a unique name: examples/sdk_create_tag_sacrificial.py.
