ops-platform-mcp

A miniature rehearsal of a real consulting-stack architecture: a mock internal ops platform (FastAPI + SQLite, standing in for BambooHR / Deltek Vantagepoint / ClickUp / an internal Django app) wrapped by an MCP server so that Claude Code can read and write platform data in natural language. The MCP layer talks to the platform only over HTTP — exactly how a connector wraps a vendor API in real life. See CLAUDE.md for the full PRD.

FastAPI "platform" (SQLite + seed)  ◄─HTTP─►  MCP server (stdio)  ◄─►  Claude Code

Quickstart

Requires uv (it will fetch Python 3.12 automatically).

uv sync                                # install dependencies
uv run python -m platform_api.seed    # create + seed ops_platform.db (re-run anytime to reset)
uv run uvicorn platform_api.main:app  # serve the platform API on http://127.0.0.1:8000

Interactive API docs: http://127.0.0.1:8000/docs

The seed is deterministic (no randomness) with relative dates: time entries are fixed offsets from the current week's Monday and task due dates are offsets from today, so "this week's utilization" always has data no matter when you run the demo. All people and clients are fictional.

Connect the MCP server to Claude Code

The platform API must be running first (see Quickstart). Then either register the server with the CLI:

claude mcp add ops-platform -- uv run --directory /absolute/path/to/ops-platform-mcp python -m mcp_server.server

…or commit/drop a .mcp.json next to wherever you run claude (if that's this repo root, the relative directory works):

{
  "mcpServers": {
    "ops-platform": {
      "command": "uv",
      "args": ["run", "--directory", ".", "python", "-m", "mcp_server.server"]
    }
  }
}

Then ask Claude Code things like:

list the employees · create a task on Atlas to "refresh the KPI deck" for Tessa · mark task 21 in progress · log 3 hours for Marcus on Orion today · pull this week's utilization report

A scripted version of this loop — including the error-path curveballs and a troubleshooting section — is in DEMO.md.

log_time(employee, project, date, hours, note?)

write

returns created entry

Tools accept human-friendly names where reasonable and resolve them to ids internally; ambiguous or unknown names return errors that list the candidates so the model can self-correct.

Task backends (Phase 3: the adapter pattern)

The three task tools (list_tasks, create_task, update_task_status) are backend-pluggable — same tool surface, different system of record:

OPS_TASK_BACKEND=platform   # default: the mock platform above
OPS_TASK_BACKEND=clickup    # real ClickUp API (set CLICKUP_API_TOKEN)

In ClickUp mode a "project" is a ClickUp list (found by name across all spaces and folders), an assignee is a workspace member, statuses map todo / in_progress / done ↔ "to do" / "in progress" / "complete", and task ids are ClickUp's alphanumeric strings. Get a personal token from ClickUp → Settings → Apps and see .env.example. CLICKUP_TEAM_ID pins a workspace when the token can see several. The other five tools (employees, hours, time, utilization) always use the platform.

This is the point of the exercise: the MCP tool layer didn't change when the backend became a real vendor API — only the adapter behind it did.

Development

uv run pytest              # 40 tests: API happy paths + error cases, MCP tool handlers
uv run ruff check .        # lint
uv run ruff format --check .

Tool-handler tests run against the real FastAPI app in-process (httpx ASGI transport + seeded in-memory SQLite) — no server or network needed. CI runs the same three commands.

What this rehearses

Directing an AI agent to build and operate the connector layer between LLM tooling and internal business systems: a typed CRUD API over a real data model, an MCP server whose tool descriptions a model can act on reliably, and the review/CI loop around both.

Next steps (not in v1): auth/OAuth on the platform API, a second adapter backed by the real ClickUp API (same tool surface, different backend), deployment.

Available Tools

8 tools
create_taskA

Create a new task on a project. Use this when asked to add a work item, to-do, or action item. project (required) and assignee (optional) accept a name, a unique name fragment, or an id; due_date is optional in YYYY-MM-DD format. New tasks always start in the 'todo' state — use update_task_status afterwards if a different status is needed. Returns the created task including its id; mention the id so the user can refer to the task later. The task is created in the system selected by OPS_TASK_BACKEND (the mock platform by default, or ClickUp).

Inputs: project (required), title (required), assignee, due_date.

get_project_hoursA

Report how a single project is tracking against its budget: returns the project's metadata plus budget_hours, logged_hours (sum of all time entries), and remaining_hours. Use this for questions like 'how is Orion tracking against budget' or before logging significant additional time. project accepts a name, a unique name fragment, or a numeric id.

Inputs: project (required).

list_employeesA

List every employee in the platform with their id, name, role, department, and weekly_capacity_hours. Use this to discover who exists, look up an employee's id or exact name, or check someone's capacity before assigning work or interpreting a utilization report. Takes no arguments and returns the full employee list; if you need a subset, filter the result yourself.

Inputs: no named parameters. Returns: result

list_projectsA

List every project with its id, name, client, status (active, on_hold, or closed), and budget_hours. Use this to discover which projects exist or to find a project's id or exact name before creating tasks, logging time, or requesting an hours report. Takes no arguments and returns the full project list.

Inputs: no named parameters. Returns: result

list_tasksA

List tasks, optionally narrowed by project, assignee, and/or status. Use this to answer what is on someone's plate, what work remains on a project, or to find a task's id before updating its status. project and assignee accept a name, a unique name fragment, or an id; status must be todo, in_progress, or done. All filters combine with AND. Returns the matching tasks with project and assignee names included for readability. Tasks live in the system selected by OPS_TASK_BACKEND (the mock platform by default, or ClickUp).

Inputs: project, assignee, status. Returns: result

log_timeA

Log hours that an employee worked on a project for a specific day. Use this when someone reports time worked or asks you to record effort. employee and project accept a name, a unique name fragment, or a numeric id; date is YYYY-MM-DD; hours must be greater than 0 and at most 24; note is an optional short description of the work. Returns the created time entry including its id. Logged time immediately shows up in get_project_hours and utilization_report.

Inputs: employee (required), project (required), date (required), hours (required), +1 more.

update_task_statusA

Move a task to a new status: todo, in_progress, or done. Use this when asked to start, finish, reopen, or otherwise progress a task. Requires the task_id — if you only know the task by title or assignee, call list_tasks first to find the id (ids are numeric on the platform backend, alphanumeric strings on ClickUp). Returns the full updated task so you can confirm the change took effect.

Inputs: task_id (required), status (required).

utilization_reportA

Per-employee utilization for one week: logged hours against weekly capacity, with a utilization_pct per person. Use this for questions like 'who is over or under capacity' or 'pull this week's utilization'. week is an ISO week string such as '2026-W24'; omit it for the current week. Returns the week's start/end dates and one row per employee (including employees with zero logged hours).

Inputs: week.

    TDQS

    A4.4/5.0

    Scored across 8 tools

    Disambiguation5/5

    Each tool has a distinct purpose covering tasks, projects, employees, and time tracking. There is no overlap; for example, create_task and update_task_status are clearly separate, and list_tasks is different from list_projects or list_employees.

    Naming Consistency5/5

    All tool names follow a consistent verb_noun pattern in snake_case (e.g., create_task, get_project_hours, list_employees). No mixing of conventions or inconsistent verb styles.

    Tool Count5/5

    With 8 tools, the count is well-scoped for an operations platform covering task management, project tracking, employee lookup, and time logging. Each tool serves a necessary function without bloat.

    Completeness3/5

    The set covers core operations (create, read, update status, list, log time, report), but lacks an update tool for task fields other than status (e.g., assignee, due date) and no delete tool. This creates a notable gap in task lifecycle management.
