Pascal Editor — Watchlist

MCP100 Assessment

Watchlist / Tracking

Why we’re tracking it

Track whether the editor's MCP bridge remains usable as WebGPU and the editor model change

Reviewed Oct 5, 2026 · Documentation review; complete setup workflow not independently tested

Best fit

Local-first 3D building modeling with browser, CLI and agent-assisted workflows.

What we know

Pascal Editor is an open-source local-first 3D building editor that runs in the browser or CLI and can be integrated into agent workflows.

All limitations / Review context

Which MCP editor operations and client integrations are supported in the next release?

The bounded assessment reviewed the official README, repository notices, security policy path, and security page for known material public-tracking blockers. No such blocker was identified. This is a public-tracking assessment, not an installation safety certification.

The project is local-first, but MCP-specific authority and authentication are not fully documented.
Depends on how the host application exposes editor capabilities.
Local-first editor; host application determines external data flow.
Reviewed write actions: Create and modify 3D building models
Sensitive access: Project/model files
Installation, client compatibility and comprehensive security have not been independently audited. Authentication and access depend on the configured services.
No independent runtime, installation, or comprehensive security audit was performed.
No installation, runtime, client matrix, or complete tool-contract audit was performed in this review.
Canonical MCP transport
Canonical single-package adoption metric
The project publishes multiple first-party packages rather than one canonical package metric.
The exact MCP transport is not clearly specified in the reviewed source.

Publisher instructions.

Source evidence observed Oct 14, 2026.

Additional setup details required — see the specific gaps below.

Download / install
Publisher instructions
Pascal Editor is a local 3D editor with an authenticated MCP service; the CLI provides editor and agent connectors.
package install · Publisher instructions
npm install --global @pascal-app/cli
self hosted install or run · Publisher instructions
npx @pascal-app/cli editor
Configure application / integrations
Publisher instructions
Pascal has local CLI MCP `pascal mcp connect` (keyless) and a separate hosted MCP. Plugin may register both; avoid duplicate active Pascal MCP servers.
Check connection
Suggested check
Use local connection tool listing; remove duplicate Claude user entry explicitly where applicable.
Disconnect / uninstall / revoke
MCP100 setup guide
Stop Pascal local editor, unregister its MCP server from agent separately; leave ~/.pascal/data/pascal.db untouched unless user chooses to remove data.
Distinguish client registration removal from software uninstall, persistent data deletion and provider OAuth/API-key revocation.
npm uninstall --global @pascal-app/cli
