Nothing to run from here
Canvs is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http canvs-mcp https://app.canvs.io/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
6 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Returns guidance on diagram-creation workflow and tool selection: how to choose between Mermaid and manual element creation, and the recommended iteration workflow. Consult before building complex diagrams.
No parameter schema on file.
Creates elements on a canvas. Creates a new canvas if room_id is omitted, or adds to the existing canvas if room_id is provided. Use cases: wireframes, UI mockups, freeform illustrations, standalone shapes, and manual layouts that Mermaid does not cover well. For diagrams Mermaid can express, use add_elements_from_mermaid instead. Element types: rectangle, ellipse, diamond, arrow, line, freedraw,
| Parameter | Type | Required | Notes |
|---|---|---|---|
| room_id | string | no | Room ID of an existing canvas to add to. If the user is continuing a canvas already referenced in this conversation (by room_id, or a URL like ?room=[room_id] or /?gdrive=[room_id]), pass it here. Omi |
| elements | array | yes | Array of element definitions to create |
Update elements on a canvas. Requires room_id from a previous Canvs tool result. Pass elements array with id and fields to update. IMPORTANT: in each update object ONLY id is required; all other fields are optional patch fields. Include ONLY elements that need changes; elements omitted from the request remain unchanged on the board. Prefer this tool for SMALL edits to existing diagrams (rename/m
| Parameter | Type | Required | Notes |
|---|---|---|---|
| room_id | string | yes | Room ID from a previous Canvs tool result. If you only have a URL, extract it from https://[host]/?room=[room_id] or https://[host]/?gdrive=[room_id]. |
| elements | array | yes | Array of element updates (each must have id) |
Delete elements from a canvas. Requires room_id from a previous Canvs tool result. Pass ids array of element IDs to delete.

| ids | array | yes | Array of element IDs to delete |
Query elements on a canvas. Requires room_id from a previous Canvs tool result. Returns elements matching optional filters. Use this before update_elements when making small edits to existing diagrams. If no browser has the canvas open, returns an error — ask the user to open the canvas URL in their browser and retry.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| room_id | string | yes | Room ID from a previous Canvs tool result. If you only have a URL, extract it from https://[host]/?room=[room_id] or https://[host]/?gdrive=[room_id]. |
| type | string | no | Filter by element type |
| filter | object | no | Additional key-value filters (e.g., {locked: true}) |
Creates diagram elements from a Mermaid definition. Creates a new canvas if room_id is omitted, or adds to the existing canvas if room_id is provided. Preferred over add_elements for new diagrams and large changes to existing diagrams whenever the content can be represented in Mermaid. Supports: flowchart, graph, flowchart-elk, sequenceDiagram, classDiagram, classDiagram-v2, stateDiagram, stateDia

—Grade not published
No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.0.

No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
