TaskLite MCP Server

Create an app, a named API surface over the boards of a project, for an external frontend. Then add endpoints and an API key.

Create an API key for an app. SECURITY: the key must live server-side only (env var, Next.js API routes), never in browser code. If the app has its own users, the server also sends `X-App-User: <user id>` with the key so per-user endpoints know who is acting.

Expose a board as a REST endpoint of an app: /apps/{appSlug}/api/{slug}. exposedColumns limits which columns are readable/writable. rowLevelSecurity.enabled makes the endpoint per-user: the developer's server sends `X-App-User: <their user id>` next to the API key, and the endpoint returns, updates and deletes ONLY that user's rows (401 without the header). Use it whenever the app has its own users.

Get the machine-readable spec of an app: base URL, endpoints, methods, fields, auth. Two formats: "tasklite" (default), the compact shape the frontend prompts are built from, and "openapi", a standard OpenAPI 3.1 document for developers and other tools. When the user asks for the OpenAPI spec, or wants to hand the API to a developer, pass format "openapi". appId accepts either the app UUID or its slug (app-xxxxxx); list_apps shows both. The returned baseUrl is absolute, use it verbatim, do not rebuild it from the admin URL.

List an app's REST endpoints, slug, board, allowed methods, and how many columns each exposes. An endpoint exposing 0 columns is broken: it returns only item metadata and silently discards writes.

Change an existing endpoint, most often to set exposedColumns on one that was created without them. Get the endpoint id from list_app_endpoints and the column ids from get_board_schema.

Create a board (a data table) inside a project. Add typed columns with create_column afterwards. kind: "tasks" (default) also gives the board the built-in task columns, status, priority, assignee, due date, tags, for work people track; "data" creates a plain table with only the columns you add, for records such as customers, products or orders (requires a TaskLite server from 2026-09-06; older servers ignore kind).

Delete a board with every item on it. Destructive and not undoable, confirm with the user first, and prefer delete_column when only part of the model is wrong.

Get a board with its full column schema (ids, names, types, settings). Call this before creating items with cells.

Rename a board or change its description. Structure (columns) is changed with update_column / delete_column / reorder_columns.

Add a typed column to a board. Valid types: text, rich_text, number, status, date, datetime, duration, people, checkbox, dropdown, label, priority, link, email, phone, relation, lookup, rollup, formula, rating, currency, file. Choose by meaning, date for dates, phone for phones, number/currency for amounts, dropdown/status (with settings.options as an array of labels) for closed choices; text is for free text only. An obvious name/type mismatch is rejected with the suggested type; pass force:true to override. Rules go in settings.validation: { unique, min, max, minLength, maxLength, pattern, patternMessage }, enforced on every write (UI, MCP, App API). Closed choices (dropdown/status) reject values outside settings.options unless settings.allowCustom is true.

Delete a column and every value stored in it. Destructive, confirm with the user first. Use update_column when the column is right but its name, type or options are wrong.

Change a column after the fact: rename it, change its type (e.g. number -> currency), replace settings (dropdown options), or set isRequired / isHidden. A type change converts existing values (number↔currency, text→number/date/checkbox, anything→text) and clears the ones that cannot convert; the response carries conversion: { converted, cleared }. settings.validation rules apply here too.

Post a comment on an item's thread. To notify people, pass their user ids in mentionedUserIds (each also appears as an @mention). attachmentIds references already-uploaded files. Needs projectId and itemId.

Delete a comment from an item thread. Destructive, confirm with the user before calling. Needs projectId, itemId and the commentId.

Edit the text of an existing comment. Only the author can edit their comment. Needs projectId, itemId and the commentId.

Create an item (row) with all of its data in one call. cells maps columnId -> value (use get_board_schema for column ids); every cell is saved with the row. Use set_cell only for later edits.

Delete an item. Destructive, confirm with the user before calling.

Update item fields (title, description, status, priority, dueDate, tags).

Create a project (a business process container). Boards with data live inside projects.

Delete a project with every board, column and row inside it. Destructive: confirm with the user first, and name the project in the confirmation. The project goes to the organization recycle bin, so it can be restored from the admin until it is emptied.

List the apps in the organization, id, slug, status. Call this first when you need an app id: the slug (app-xxxxxx) is what shows up in URLs and in generated code, and this is how you map it back to the app.

Create an automation on a board: when something happens, do something. The most useful action here is http_request, which calls an external API and writes the answer back into columns, pair it with the "scheduled" trigger and the board keeps itself up to date (prices, exchange rates, shipment status, weather). Triggers: item_created, status_changed, column_value_changed, date_approaching, scheduled. Actions: http_request, send_notification, send_email, change_status, set_column_value, create_cross_board_item, send_webhook. Two more things every action list can use: a { type: "delay", config: { minutes | hours | days } } action pauses the run and resumes the actions after it later (reminders, follow-ups); and any network action (http_request, send_webhook, send_email, send_whatsapp) may carry config.retry: { attempts (1-5), delaySeconds (1-60) }. send_webhook accepts config.secret for an HMAC signature.

List the automations on a board, so you can see what already runs before adding another.

List the boards inside a project, id, name, description. Every other board tool needs a boardId, and this is the only way to discover one without being handed a URL.

Build a whole backend in one call from a spec you compose: the project, its boards, their typed columns (including relations between the boards), optional sample rows, and optionally a published REST API with one endpoint per board and a server-side key. Use it whenever the user describes a system ("a backend for my repair shop: customers, orders, payments") instead of calling create_project, create_board, create_column, create_app, publish_app, create_app_endpoint and create_app_api_key one by one. You do the design, pick column types by meaning (phone, date, currency, dropdown/status with options for closed choices), link boards with a relation column (type "relation", relatedBoard: "<board name in this spec>", relationType: many_to_one for an order→customer link), and this tool executes it and returns one compact summary. API field names are derived from column names and never collide with reserved item fields, so there is nothing to retry. Boards are created as plain data tables (kind "data": only the columns you define, no task fields); set kind "tasks" on a board where people track work to do and want status, priority, assignee and due date built in. Every row still has a title.

Set a single cell value on an item by columnId.

List the comments (the correspondence thread) on an item, oldest first. Each comment includes its author and any @mentions. Needs projectId and itemId (get itemId from query_items).

Read or change how EXTERNAL users (people who sign up to your app through TaskLite auth) get into an organization. They have two ways in, and both obey the policy below: email and password (POST /auth/register-external with this organizationId, then POST /auth/login), or Google (POST /auth/google-external with a Google ID token and this organizationId). Either way the answer carries a token the app sends as Authorization: Bearer on every App API call. registrationPolicy: "open", in at once; "approval", an organization admin approves each signup (TaskLite mails the admins on every signup, and the person once approved; unapproved users are never billed); "closed", invite only, self-signup refused. appLoginUrl: the page of YOUR app where these users log in, it becomes the "Log in" button in the approval email, so set it whenever you deploy an app that uses this flow; pass "" to clear. Call with no changes to just read the current settings. Requires organization admin.

Deploy a static frontend to TaskLite hosting and get a live URL https://{slug}.tasklite.dev (HTTPS, auto-published on first deploy, versions kept for rollback_deployment). Hand over the frontend in ONE of three ways: `files`, the files inline (path + content), the way to go from ChatGPT or any hosted client: write index.html and its assets, then deploy in the same turn; `zipUrl`, a public https URL of a zip (a Lovable/Bolt export, a GitHub release asset); `dir`, a build output folder on this machine (only when the MCP runs locally next to the files). A real build that already exists on the person's machine fits none of these from a hosted server: tell them to drop the zip on the app's Versions screen (the adminUrl of the app, then Versions), which deploys the same way and keeps the same version history. In the frontend, call the app API via relative /api/{endpoint}, the hosting proxy injects the app identity, so no key ships to the browser.

List the hosted-frontend deployments of an app, versions, which one is live, and the public URL.

The whole project as JSON, boards, columns with settings, items with their cells keyed by column id. For migrations, backups and reading a system back. Items are capped per board for the model's sake; the REST endpoint GET /organizations/{orgId}/projects/{projectId}/export.json returns everything.

One project, board or item in full, by the id search returned (project:<id>, board:<projectId>:<boardId>, item:<projectId>:<boardId>:<itemId>) or by an app URL path. Returns { id, title, text, url, metadata }, the ChatGPT fetch contract; text is the record as JSON.

Get a ready-made prompt describing the app backend, for pasting into a frontend generator (v0/bolt/lovable/cursor). appId accepts the app UUID or its slug (app-xxxxxx), use list_apps to find it.

List items (rows) of a board, including their cell values. Returns all items unless limit/page are given (the API defaults to 50 per page when unpaged, so the tool pages through and concatenates). Narrow the result with search, status, priority and sort instead of fetching everything. This is the admin view; the REST endpoints of a published app take a fuller grammar, filter[column][gte], relation filters, per-field search, see get_app_spec.

List the organizations the authenticated user belongs to. Use the returned id as organizationId in other tools.

List projects in an organization. The API returns 50 per page, an organization with more than that needs page 2 and beyond, so check the returned total before assuming a project does not exist.

Publish an app, required before its API endpoints accept external calls.

Whether an app can send push notifications to phones, and how many devices are registered. Push goes out through the customer's OWN Firebase project, so it has to be configured once per app before send_push automations do anything. This tool never returns the key.

Set the display order of a board's columns. Pass every column id in the wanted order (get_board_schema lists them).

Create a link that puts files onto an item from outside TaskLite: the customer's photos, a signed contract, a logo, a build zip. Returns an address like https://app.tasklite.net/upload/<token> that anyone you hand it to can use with no account, no login and no API key; pass clientEmail and TaskLite emails the link for you. What arrives lands as attachments on that item, and list_uploaded_files reads them back with a download URL. This is the answer when the person has the file and the model does not: a hosted client cannot read a folder on someone's machine. The link is public for as long as it lasts, so keep expiryDays short and maxFiles tight, and revoke_upload_link when the material is in.

Close an upload link before it expires, so the address stops accepting files. The files already uploaded stay on the item. Use it as soon as the material is in, because until then anyone holding the link can add more.

Point the live URL back at a previous deployment version (see list_deployments for available versions).

Full-text search across the projects, boards and items of the organization. Returns { results: [{ id, title, url }] }, the shape ChatGPT connectors and deep research expect; pass a result id to fetch for the full record. When you already know the board, query_items is cheaper and complete.

Send one real push notification to the given app users, to prove the chain works before an automation depends on it. Confirm with the user first: this reaches actual phones.

The files attached to an item, including everything that came in through a request_file_upload link, each with a download URL that is signed and short lived (mint a fresh one by calling again). Also lists the upload links on the item and how many files each has taken, which is how to tell whether the person you asked has delivered.
