Microsoft Planner tools (16, 5 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • graph_find_endpoint

    Discover which Microsoft Graph endpoint (and its query params) fits a task — search a curated catalog

  • graph_get

    Read-only GET for any Microsoft Graph v1.0 path under /planner, /groups or /users (delegated sessions

  • planner_create_bucketwrite action

    Create a new bucket (column) in a plan.

  • planner_create_taskwrite action

    Create a Planner task in a plan. Optionally set the bucket, due date, priority, assignees, labels, and a description.

  • planner_delete_taskwrite action

    Permanently delete a Planner task. This cannot be undone.

  • planner_find_user

    Find a user by display name or UPN/email to get the user ID needed for task assignments and planner_list_user_tasks.

  • planner_get_plan

    Get a Planner plan with its buckets and labels. Bucket IDs are needed to create or move tasks; label names are accepted by the task tools' label fields.

  • planner_get_task

    Get a Planner task including its description and checklist. Also returns the etags needed by update tools (updates fetch them automatically).

  • planner_list_my_plans

    List the Planner plans the session's signed-in user has access to — no group ID or guessing needed.

  • planner_list_plans

    List all Planner plans owned by a Microsoft 365 group. Get the group ID from planner_search_groups.

  • planner_list_tasks

    List Planner tasks in a plan (or a single bucket). Optionally filter by assignee user ID or open/completed state.

  • planner_list_user_tasks

    List all Planner tasks assigned to a user across every plan they participate in. Get the user ID from planner_find_user.

  • planner_search_groups

    Search Microsoft 365 groups (Teams) by display name. Use this first to find the group ID required by planner_list_plans.

  • planner_update_taskwrite action

    Update a Planner task: title, bucket (move), due date, priority, progress (not started / in progress / completed), assignees, or labels. Fetches the current etag automatically.

  • planner_update_task_detailswrite action

    Update a task's description, add checklist items, or check/uncheck existing checklist items (item IDs come from planner_get_task).

  • planner_whoami

    Show who this session acts as: app-only (client credentials, writes attributed to the app) or delegated

Install Microsoft Planner in Claude Code, Cursor or VS Code

Runs npx -y mcp-planner on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Microsoft Planner repository's README, as published. We do not edit it. Read it on GitHub

mcp-planner

MCP server for Microsoft Planner via the Microsoft Graph API. Find groups and plans, list buckets and tasks, and create, update, assign, complete, or delete tasks — including descriptions and checklists — with Planner's ETag concurrency handled automatically.

Sibling project to mcp-itglue and mcp-connectwise-psa — same architecture.

Tools

† Advanced toolset (opt-in, off by default) — an escape hatch for Graph surface the curated tools don't wrap. Enable with PLANNERADVANCEDTOOLSET=true or --advanced. graph_get is verb-locked to GET, rejects /beta, and only reaches the three path prefixes above, so a shared app registration's other permissions (e.g. mail) stay out of reach.

Setup

1. Entra ID app registration

  1. Entra admin center → App registrations → New registration
  2. API permissions → Application permissions → add Tasks.ReadWrite.All, GroupMember.Read.All, User.Read.All → Grant admin consent
  3. Certificates & secrets → New client secret — note the value

2. Run

MS_TENANT_ID=<tenant> MS_CLIENT_ID=<client-id> MS_CLIENT_SECRET=<secret> npx -y mcp-planner

Claude Code:

claude mcp add planner --env MS_TENANT_ID=<tenant> --env MS_CLIENT_ID=<client-id> --env MS_CLIENT_SECRET=<secret> -- npx -y mcp-planner

HTTP mode

npx -y mcp-planner --transport http --port 3000

Sessions authenticate per-request (BYOK) with x-ms-tenant-id + x-ms-client-id plus either x-ms-client-secret (app-only) or x-ms-refresh-token (delegated — see below), or fall back to the MS_* environment credentials when set. When both a secret and a refresh token arrive, the refresh token wins (header-overlay proxies can add but not remove headers). Health probe at GET /health.

Delegated mode — act as the signed-in user

App-only sessions act as the app registration; delegated sessions act as a user: their Planner permissions apply and every write is attributed to them.

  1. A separate, public app registration: Authentication → Allow public client flows → Yes; API permissions → Delegated Tasks.ReadWrite, Group.Read.All, User.ReadBasic.All (+ admin consent where the tenant requires it).
  2. Each user signs in once via the device-code helper and keeps the printed refresh token:
node scripts/device-login.mjs --tenant <tenant-id> --client <public-client-id>
  1. Use MSREFRESHTOKEN instead of MSCLIENTSECRET (stdio), or the x-ms-refresh-token header (HTTP). Behind the MCP gateway, register it as a personal credential (field x-ms-refresh-token).

The refresh token is a secret — it acts as you — and stays valid ~90 days past its last use; re-run the helper when it expires.
