Installation
Set up the Whimsical MCP server in Gumloop
Do this once to provision your hosted server URL.
Create a Gumloop account
To use this MCP, you need a Gumloop account. If you don't have one yet, sign up and start a 14-day free trial.
Add and authorize the Whimsical server
In Gumloop, open Connectors and add Whimsical. Depending on the app, you'll either sign in via OAuth or paste an API key. Either way, the credential is stored securely in Gumloop.
Then use it in your client
Use in GumloopUse Whimsical in an agent
Once Whimsical is set up, just open any Gumloop agent, add Whimsical as a connector, and start chatting with the agent.

How To
Look up Whimsical-specific syntax, examples, and guides. MUST call before creating flowcharts or wireframes. NOT needed for mind maps (pass data.markdown) or simple sequence diagrams (use arrow syntax in data.diagram). Call with no args to see available topics and stamps. Pass `domain` for structured JSON lookups (icons/colors/font-sizes/kinds) instead of markdown topics.
Create
Create content in Whimsical — diagrams, folders, or boards. Pick by intent: source is a sketch, hand-drawn note, photographed whiteboard, or any layout where absolute positions matter → type:'board' (pass data.items for one-shot creation; MUST call how_to('board') first). Source describes semantic structure (steps, hierarchy, sequence, UI) → flowchart, mindmap, sequence_diagram, or wireframe — these auto-layout. Mind maps: pass data.markdown directly (no how_to needed). Sequence diagrams: use data.diagram with arrow syntax (A -> B: msg) — no how_to needed for basic diagrams. Flowcharts: MUST call how_to('flowchart') first for the structured format. Wireframes: MUST call how_to('wireframe') first. For documents, use `doc_create`.
Doc Create
Create a Whimsical document. Markdown content — headings, lists, links, code blocks. For diagrams, boards, or folders, use `create`.
Generate Diagram
Auto-laid-out semantic diagrams ONLY (flowchart, mind map, sequence diagram). DO NOT use for sketches, hand-drawn notes, photographed whiteboards, or any input where absolute positions matter — even if the user says 'diagram' — use create(type:'board') instead (see how_to('board')). Mind maps: pass data.markdown directly (no how_to needed). Sequence diagrams: use data.diagram with arrow syntax (A -> B: msg, A --> B: dashed, A ->> B: open arrow) — no how_to needed for basic diagrams. Flowcharts: MUST call how_to('flowchart') first for the structured format.
Generate Mind Map
Generate a Whimsical mind map from indented text. Format: first line is root, children use '- ' bullets, indent 2 spaces per level. Example: 'Root Topic\n- Child 1\n - Grandchild\n- Child 2'
Generate Wireframe
Generate a Whimsical wireframe with flexbox layout — containers, buttons, inputs, images, icons. IMPORTANT: ALWAYS call how_to('wireframe') first and use the Whimsical-specific syntax — wireframes use a flexbox DSL that requires the correct format.
Delete
Move a Whimsical file, folder, or doc to trash. The item can be restored from the Whimsical trash UI. Pass the item id from a previous file_tree or search result. To delete shapes, text, or connectors inside a board, use the `edit` tool with a `delete` operation instead.
Edit
Edit a Whimsical board or doc. Fetch the board first to get object IDs. Boards: add/update/delete shapes, text, connectors (use temp_id), icons, tables; find_replace/delete_by_text for compound diagrams; mm_update to restructure mindmaps; sd_update for sequence diagrams. Docs: update_block/insert_after_block/append_blocks/delete_block (all markdown). Use how_to('edit') for advanced syntax (table columns, group ops, doc table ops).
Search
Search workspace files and content by name or full text.
Fetch
Read boards, docs, or folders by ID. Returns text by default; set image=true for a PNG snapshot. Use scope to drill into a group, select_kinds to filter by type, grep_text to search.
File Tree
Browse the workspace file hierarchy. With no arguments, lists the Private, Shared, and team sections (teams are sections within a workspace, not separate workspaces) plus the folders and files inside each. Pass filter="teams" to list just the teams (name + id). Pass folder_id — a folder, section, or team id — to list the tree below that parent.
List Workspaces
List all workspaces the user belongs to, with the teams in each. Returns workspace IDs, names, role ("member" can create content / "guest" is read-only), and each workspace's teams (id + name). Teams are sections within a workspace — pass a team id as parent_id to create content in that team.
