mcp-ado

A FastMCP server that scans your team's Azure DevOps work items (by area path), flags anything overdue or stale (not updated in N days), and emails each assignee their own list — sent as you via delegated Microsoft Graph.

It also drills into a stalled item (comments, link graph, revision history), reports what is blocking it, reads and writes wiki pages, and can comment on / update / create work items — with writing off by default and gated twice.

How it works

1. ADO — a WIQL query returns open (non-done) items UNDER your area path using a PAT (Work Items → Read). Fields are batch-fetched.

2. Flagging — an item is flagged if its Due/Target date is past, or its ChangedDate is older than STALE_DAYS. Results are grouped by assignee.

3. Email — each assignee gets an HTML reminder listing only their items, sent from your mailbox via Graph /me/sendMail. Auth is the Windows WAM broker (no secret, no pasted token) — same pattern as the ADF MCP.

Setup

git clone https://github.com/rajivdatta/mcp-ado.git
cd mcp-ado
python -m venv .venv
.\.venv\Scripts\python.exe -m pip install -r requirements.txt
Copy-Item .env.example .env             # then edit .env
Copy-Item targets.example.json targets.json   # optional, see below

Fill in .env:

• ADO_ORG_URL, ADO_PROJECT, ADO_AREA_PATH, ADO_PAT

• STALE_DAYS (default 7), optional ADO_WORK_ITEM_TYPES / ADO_EXCLUDE_STATES

• ADO_ITERATION_PATH — optional; @current auto-detects the sprint whose start/finish dates contain today

• TRACK_PEOPLE — optional CSV of assignee emails; when set, only those people's items are flagged. Blank = everyone.

• ENABLE_SEND — master kill-switch for email, default off

• MAIL_CC / MAIL_FALLBACK_TO (optional)

Not sure of your area path? After setting org/project/PAT, call list_area_paths to print the tree.

Getting the ADO personal access token

A PAT is the credential this server uses to talk to Azure DevOps. Grant the narrowest scope for the tools you actually intend to use — there is no reason to hand it Full access:

Read-only is the right default: with ENABLE_WRITE=false (the shipped value) the write tools refuse before making any request, so a read-only PAT loses you nothing.

1. Sign in to your Azure DevOps organization: https://dev.azure.com/YOUR_ORG

2. Open User settings (the icon beside your avatar, top right) → Personal access tokens. Direct link: https://dev.azure.com/YOUR_ORG/_usersSettings/tokens

3. Click + New Token.

4. Fill in the token:

   • Name — anything memorable, e.g. mcp-ado

   • Organization — the org holding the work items. If you belong to several, a token scoped to one org will not work against another.

   • Expiration — pick the shortest window you'll tolerate re-issuing.

5. Under Scopes, choose Custom defined, then expand Work Items and tick Read. Leave everything else unchecked.

6. Click Create, then copy the token immediately — Azure DevOps shows it exactly once and you cannot retrieve it afterwards.

7. Paste it into .env as ADO_PAT=..., then verify with the test_connection tool, which reports the open-item count on success.

.env is listed in .gitignore, so the token stays out of git. Keep it that way — a PAT is a bearer credential, so anyone holding it has your read access until it expires or you revoke it.

When it stops working. PATs expire, and an expired or revoked token fails every call. If test_connection starts returning an authentication error — or an HTML sign-in page instead of JSON — re-issue the token at the same Personal access tokens page and update .env. Two other causes worth ruling out: the token was scoped to a different organization than ADO_ORG_URL, or it lacks the Work Items → Read scope. Some organizations also restrict who may create PATs at all; if + New Token is unavailable, your Azure DevOps administrator has to permit it.

Note that the email side uses no PAT — it signs in through the Windows WAM broker instead, so ADO_PAT only ever governs reading work items.

Scanning more than one team

Drop a targets.json next to server.py to scan several project/area/iteration combinations in one pass (org + PAT stay global in .env):

[
  { "name": "Data", "project": "YOUR_PROJECT",
    "area_path": "YOUR_PROJECT\\Your Team", "iteration_path": "@current" }
]

Items are de-duplicated by id across targets, and a person with flagged items in several targets gets one combined email. Without targets.json, the ADO_PROJECT / ADO_AREA_PATH / ADO_ITERATION_PATH env values are used as a single target.

Tools

Read-only

Changes something — each gated twice

Safety model. Nothing outside your machine changes unless you opt in twice: an .env master switch (ENABLE_WRITE / ENABLE_SEND, both default off) and an explicit confirm=True on the call. Extra guards:

• update_work_item and create_work_item accept validate_only=True, which asks Azure DevOps to validate the change and save nothing — a real dry run against the server, usable even with ENABLE_WRITE=false.

• create_or_update_wiki_page always reads the page first and reports what would change. Overwriting an existing page also needs allow_overwrite=True, because the whole page is replaced, not merged — and the response echoes the previous content so an unwanted overwrite is recoverable.

• The first Graph call pops a WAM sign-in; after that it's silent.

Drilling into a stalled item

scan returns a dozen summary fields per item — enough to flag it, not enough to explain it. get_work_item adds the discussion, the parent/child chain, and a per-revision changelog, so you can tell a genuinely untouched item from one being nudged without progress:

scan(only_flagged=True) → get_work_item(id=33740, include_history=True)

blocked_items answers the related question — is this stalled because of someone else? It reports items whose state/tags declare them blocked, plus items with an unfinished predecessor link, naming the blocker. Chasing an assignee whose work is gated on another open item is how reminder emails lose their credibility.

Suggested flow

test_connection → scan → preview_notifications → send_notifications(confirm=True)

Add to your MCP config (claude_desktop_config.json for Desktop, or via claude mcp add for Claude Code):

  "mcpServers": {
    "ado": {
      "command": "C:\\path\\to\\mcp-ado\\.venv\\Scripts\\python.exe",

Notes

• Delegated Mail.Send consent. The broker signs in with the Azure CLI first-party client by default. If tenant policy blocks Mail.Send consent for it, register a public-client app with delegated Mail.Send + User.Read and set GRAPH_CLIENT_ID to its id.

• Scheduling. For a daily run, wrap send_notifications(confirm=True) in a small script and drive it from Windows Task Scheduler, or ask Claude to run the tool on a schedule.

• Dates are compared in UTC.
