## Tools

12 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `list_workspaces` — List all workspaces in your CanvasKeep account. Returns each workspace's id and name. Use this first to find the workspace_id needed by other tools.
- `create_workspace` — Create a new workspace. Returns the new workspace's id and name.
- `list_folders` — List all folders in a workspace. Returns each folder's id, name, and parent_folder_id. Use folder ids when creating diagrams inside a specific folder.
- `create_folder` — Create a new folder in a workspace. Returns the new folder's id and name. Optionally nest it inside an existing folder.
- `list_diagrams` — List all diagrams in a workspace. Returns each diagram's id, title, and last updated timestamp.
- `create_diagram` — Create a new empty diagram in a workspace, optionally inside a folder. Returns the new diagram's id. Use generate_diagram afterward to populate it with content.
- `update_diagram` — Update a diagram's title (rename it).
- `delete_diagram` — Permanently delete a diagram and its content. This cannot be undone.
- `get_diagram_summary` — Get a summary of an existing diagram: its title, workspace, element count, and when it was last updated. Does NOT return the raw scene data.
- `get_diagram_scene` — Read the raw Excalidraw scene of a diagram: the full elements array (with ids, x/y, width/height, styles, text, arrow bindings) and appState. Use this before sa
- `save_diagram_scene`
- `generate_diagram`

## Install

**Verdict: review** — Installable, but 1 thing to check first: No publisher has proved control of this listing; it is indexed, not vouched for.
**Cautions** (coverage gaps and advisories — never blocking)
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"canvaskeep\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"canvaskeep-mcp\"\n      ],\n      \"env\": {\n        \"CANVASKEEP_API_KEY\": \"<YOUR_CANVASKEEP_API_KEY>\",\n        \"CANVASKEEP_MASTER_KEY\": \"<YOUR_CANVASKEEP_MASTER_KEY>\"\n      }\n    }\n  }\n}"
```
**Credentials it will ask for** (names only — Forge never holds a value):
- `CANVASKEEP_API_KEY` — Canvaskeep API Key (required)
- `CANVASKEEP_MASTER_KEY` — Canvaskeep Master Key (optional)
Placeholders only. Forge never holds, brokers, or transmits a credential value — replace each <YOUR_NAME> in your own config file. Do not send a value back to Forge; no Forge endpoint accepts one.
- This entry needs 2 credentials (1 required). The generated config carries placeholders, so it will fail in the editor rather than at runtime if they are left unset.

## Blast radius

Extensive blast radius — deletes data; holds an api key.
- Floor 54, ceiling 54 (tier: extensive)
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
