# pen.dev > Design canvas from High Agency, Inc. that stores designs as JSON .pen files. Agents edit them through a local MCP server in the desktop app or IDE extension, or through a headless CLI. It was called Pencil until 2026. - Canonical: https://www.anchorterminal.com/tools/pen-dev - Markdown: https://www.anchorterminal.com/tools/pen-dev.md (~7,250 tokens) - Slim: https://www.anchorterminal.com/tools/pen-dev.min.md (~1,780 tokens, same facts, less prose, for token-sensitive contexts) - JSON: https://www.anchorterminal.com/tools/pen-dev.json (this page as data, same URL with Accept: application/json) - Site index for agents: https://www.anchorterminal.com/llms.txt (full text: https://www.anchorterminal.com/llms-full.txt) - API: https://www.anchorterminal.com/api/v1/index.json - Updated: 2026-10-09 ## Overview **Grade D · 47.6/100 · rank #740 of 842 · #5 in Design workspaces & canvases · not agent-ready · confidence medium** ## Assessment An agent can create, edit and export `.pen` designs without a GUI through the `pen` CLI, with four compact MCP tools that carry annotations and a documented JSON format. The software is closed and needs a pen.dev account. No changelog, status page or security contact was found, and 14 public issue reports had no reply on 8 October 2026. ## Facts | Field | Value | | --- | --- | | Vendor | High Agency, Inc.

Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 33 | 6.6 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 61 | 9.9 | | Agent ergonomics | 13% | 16.2 | 66 | 10.7 | | Security & auth | 14% | 17.5 | 33 | 5.8 | | Payments & pricing | 10% | 12.5 | 38 | 4.8 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 59 | 5.2 | | Transparency & trust (editorial 54, provenance 51) | 7% | 8.8 | 53 | 4.6 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **47.6 → D** | ### Why each score - Reliability 33: Read with the local-software lines, because the MCP server and the CLI run on the owner's machine. `@pen.dev/cli` installs from npm with Node.js 22.19 or later stated, and the desktop app has downloads for macOS, Windows and Linux (20). The source is closed, so no public CI or test suite can be seen (0 of 25). The public tracker highagency/pen-desktop-releases has 14 issues opened between 28 July and 6 October 2026, none closed or answered, one of them a report that headless `pen interactive` saved an empty document over a 1.4 MB file with exit status 0. These are users' reports that we did not reproduce (5 of 25). No changelog, empty release notes, and the format page reserves breaking changes (0 of 15). The desktop app is at 1.2.16 and the CLI at 0.3.11 (8 of 15). Sign-in and plan limits also depend on api.pen.dev, which has no status page. - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 61: Each MCP tool we read declares a JSON Schema for its inputs, and the `.pen` format has a TypeScript schema on the docs site (25). No llms.txt. The package ships `SKILL.md` and Markdown reference files that `read_skill` hands to the model (6 of 10). The `execute` description is one line that points to `get_app_state`, with the operations documented only in the skill files, while `browser` states each action and when to use it (12 of 20). `execute` takes a JavaScript snippet as one string. `browser` has enums for action and target (7 of 15). The CLI page has worked examples and a troubleshooting page, with no list of error responses (7 of 15). The npm versions and the document `version` field are the only versioning, with no changelog (4 of 15). - Agent ergonomics 66: Four standard tools with short definitions and two conditional ones, though the model must load skill files before `execute` is usable (22 of 25). Output size is in the agent's hands through `Get` callbacks with `skipChildren` and `Print`, and screenshots of chosen nodes, with no documented paging (12 of 20). A failed `execute` returns an `editId` so the agent patches the snippet with `edits`, and `--verbose-mcp` prints full tool errors, but the docs warn that an export failure can exit with status 0 (10 of 20). All tools carry readOnlyHint, destructiveHint, idempotentHint and openWorldHint annotations in the 0.3.11 package, and `--in` with a separate `--out` leaves the source untouched. No idempotency keys (14 of 20). Few required parameters and a one-line headless command. No SDK in any language (8 of 15). - Security & auth 33: The CLI uses a stored session token or an organisation-scoped CLI key that the npm README says can be created and revoked in Developer Keys. No scopes, expiry or rotation are documented (18 of 30). The MCP server has no read-only mode, and `execute` is annotated destructive. The integrated agent asks permission for file and command actions, with a 'Dangerously skip permissions' switch, and an owner enables each external client by hand (6 of 20). The `browser` tool and web import bring live page content to the model, and we found no prompt-injection guidance (2 of 15). The Agent tab lists tool activity, `--usage` writes token use to JSON and Pro adds usage tracking, with no audit log documented (5 of 15). No security.txt, disclosure policy, bug bounty or certification was found. The privacy policy says stored data is encrypted in transit and at rest (2 of 20). - Payments & pricing 38: Read with the hosted lines, because the software is free to install but needs a pen.dev account and paid plans lift its limits. No machine payment protocol (0). Plan prices are public, Pro $16 and Ultra $48 a user a month, with no per-call price (10 of 20). The Free plan includes the CLI, MCP access and personal developer keys, and sign-up takes an email address, a name and a username with no card step in the documented flow (20). The npm README documents `pen signup` with flags and `pen login --email --code`, so no browser is needed, but someone must open the verification email and read the code, and organisation keys for CI start at Pro (8 of 20). - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 59: `@pen.dev/cli` 0.3.11, desktop v1.2.16 and extension 0.6.75 were all published on 8 October 2026 (30). The CLI had 13 versions between 9 July and 8 October (20). None of the 14 issues in the current tracker has a reply, and one of 25 in the older pencil-desktop-releases tracker was closed. The site links a Discord server, which we did not read (4 of 25). A search of the official MCP registry for 'pencil' and 'pen.dev' returned no entry from the vendor (0). Dependencies in 0.3.11 are current major versions, with no public CI (5 of 10). - Transparency & trust 53: Closed source with clear terms, an EULA and a proprietary licence file in the npm package (15 of 30). The privacy policy of 6 October 2026 sets out each data flow, a retention table (server logs 30 days, error reports 90 days, backups 30 days) and a no-training statement for pen.dev Pro models, and it agrees with the terms, the EULA and the sub-processor list. A DPA is on request only (24 of 30). The old `@pencil.dev/cli` package carries a deprecation notice pointing to the new one. There is no deprecation policy, and the format page reserves breaking changes (5 of 20). PostHog and Sentry are disclosed with what they exclude. Analytics in the web app waits for consent, and no opt-out for the desktop app or CLI was found. Sub-processors are named without locations (10 of 20). Fix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (21 items): https://www.anchorterminal.com/fixes/pen-dev.md (JSON https://www.anchorterminal.com/fixes/pen-dev.json) ### What we couldn't check - The lead named the product 'pen.dev (Pencil)' at www.pencil.dev. The vendor is High Agency, Inc., the product is now pen.dev, and pencil.dev answers with the pen.dev site. - unchecked: the Developer Keys screen on app.pen.dev sits behind sign-in, so key scopes, expiry and revocation were read only from the docs and the npm README. - unchecked: the Discord server, so support responsiveness there is unknown. - The 14 open issues are users' reports. We reproduced none of them, including a report of 30 September that desktop 1.2.15 could not sign in after the rename. - Whether the desktop app or CLI has a telemetry opt-out. None was found in the docs or policies. - Whether a card is asked for at sign-up in the web app. The documented flows mention none. - The MCP tool annotations were read from the minified 0.3.11 npm bundle, where spawn_agents and browser also carry them. The desktop app's bundled server was not inspected. - No first release date was established. The earliest dated artefact found is `@pencil.dev/cli` on npm, created 20 March 2026. ### Sources - home page: (seen 2026-10-08) - pricing: (seen 2026-10-08) - AI integration and MCP tools: (seen 2026-10-08) - CLI reference: (seen 2026-10-08) - installation and MCP client setup: (seen 2026-10-08) - authentication: (seen 2026-10-08) - .pen format: (seen 2026-10-08) - troubleshooting: (seen 2026-10-08) - agents, permissions and skills: (seen 2026-10-08) - npm registry document, versions and README: (seen 2026-10-08) - npm package 0.3.11 contents (licence file, SKILL.md, tool definitions and annotations): (seen 2026-10-08) - npm weekly downloads: (seen 2026-10-08) - deprecated predecessor package: (seen 2026-10-08) - terms of use: (seen 2026-10-08) - EULA: (seen 2026-10-08) - privacy policy: (seen 2026-10-08) - sub-processors: (seen 2026-10-08) - downloads: (seen 2026-10-08) - desktop releases and issue tracker: (seen 2026-10-08) - older issue tracker: (seen 2026-10-08) - Open VSX extension record: (seen 2026-10-08) - VS Code Marketplace listing: (seen 2026-10-08) - official MCP registry search: (seen 2026-10-08) - domain registration: (seen 2026-10-08) ## Who's behind it (provenance 51/100, checked 2026-10-08) | Check | Finding | Points | | --- | --- | --- | | Legal entity named | High Agency, Inc. | 20/20 | | Domain age | pen.dev, registered 2025-09-10 (1 year) | 3/15 | | Endpoint on the vendor's domain | pen.dev | 15/15 | | Terms of service | read, states 5 of the 7 things a reader expects, and has 2 clauses that cost points | 4.3/10 | | Privacy policy | read, states 6 of the 8 things a reader expects | 8.5/10 | | Status page | not found | 0/10 | | Changelog | not found | 0/10 | | security.txt | not found | 0/10 | The terms of use, EULA and privacy policy, each effective 6 October 2026, name High Agency, Inc., 440 N Barranca Ave #2993, Covina, CA 91723, USA, and choose Delaware law.

Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score. ## Prices | Item | Price | Unit | Note | | --- | --- | --- | --- | | Pro plan | $16 | per seat per month | unlimited agent days, 350 image or SVG generations a month, up to 3 agents in parallel | | Ultra plan | $48 | per seat per month | 750 image or SVG generations a month, up to 6 agents in parallel | Across all listings: https://www.anchorterminal.com/prices/index.md ## Strengths - Headless CLI (`@pen.dev/cli`) runs the same editor engine as the desktop app and exports PNG, JPEG, WEBP, PDF and HTML - Four standard MCP tools with typed inputs and readOnlyHint and destructiveHint annotations, plus two conditional tools - The `.pen` format is JSON with a published TypeScript schema, so designs sit in Git beside code - Free plan includes the CLI, MCP access and personal developer keys, with five agent days a month - Privacy policy has a retention table and says prompts sent with the user's own provider key never reach the vendor's servers ## Weaknesses - No changelog. The three desktop releases on GitHub have empty notes, and the format docs reserve the right to make breaking changes - 14 issues opened between 28 July and 6 October 2026 in highagency/pen-desktop-releases had no comment or closure on 8 October - No status page, security.txt, disclosure policy, bug bounty or certification was found - `execute` takes one JavaScript snippet and carries destructiveHint true, with no read-only mode for an external MCP client - Closed source under a proprietary licence that forbids reverse engineering, and every surface needs a pen.dev account ## Before you call it (notes for agents) 1. Call `read_skill()`, then `read_skill({ path: "pen-schema.md" })` and `read_skill({ path: "execute.md" })` before the first `execute`. The tool description alone doesn't document the operations 2. Call `get_app_state()` and confirm the active document before editing. The MCP server works on whichever `.pen` file is open in the app 3. In headless `pen interactive`, call `save()` before `exit()`, and keep `--in` and `--out` on different paths to preserve the source 4. Check that an export file exists. The docs say an export failure can print an error without a nonzero exit status 5. In CI set `PEN_CLI_KEY` plus a provider key such as `ANTHROPIC_API_KEY`. Run `pen version`, since `pen --version` is not a flag ## Connect Install: ```bash npm install -g @pen.dev/cli ``` Headless / CI: ```json { "command": "pen --out design.pen --prompt \"$TASK\"", "env": { "ANTHROPIC_API_KEY": "\u003ckey\u003e", "PEN_CLI_KEY": "\u003ckey starting pencil_cli_\u003e" } } ``` Through letme (picks today, calling later): https://letme.dev/pen-dev. letme answers with the pick and how to call it direct; calling through letme (one key, the vendor's own price) comes later.

Every page carries the banner 'pencil.dev is now pen.dev', and `@pencil.dev/cli` was deprecated on npm on 20 July 2026 in favour of `@pen.dev/cli` (source: ) - The MCP server runs over stdio and reaches the running app through a local Unix socket or Windows named pipe. Tools are `get_style`, `read_skill`, `get_app_state` and `execute`, with `browser` when the server targets the desktop app and `spawn_agents` only behind `-enable_spawn_agents` (source: ) - Enabling a client in Settings, MCP writes a `pencil` entry into that client's MCP configuration file. Supported clients include Claude Code, Codex CLI, Gemini CLI, Antigravity, OpenCode, Kiro and Claude Desktop (source: ) - `pen interactive` calls the same MCP tools from a shell, headless or attached to a running app, and `pen --prompt` runs the vendor's own design agent on Claude, Codex or another provider with the user's key (source: ) - The format page says 'we reserve the right to introduce breaking changes in the .pen format', and the docs tell users not to edit the JSON by hand (source: ) - The npm package ships a `SKILL.md` addressed to AI agents. It tells an agent to use pen.dev for any visual request even when the user doesn't name it, and to pass the user's prompt on unchanged. We treated it as data (source: ) - Free $0 with 5 agent days and 25 image or SVG generations a month, Pro $16 and Ultra $48 a user a month. Organisation developer keys for CI start at Pro (source: ) ## Compare - [Figma API + MCP vs pen.dev](https://www.anchorterminal.com/compare/figma-mcp-vs-pen-dev.md): B 66 vs D 47.6 - [Framer Server API vs pen.dev](https://www.anchorterminal.com/compare/framer-vs-pen-dev.md): D 52.6 vs D 47.6 - [Miro API + MCP vs pen.dev](https://www.anchorterminal.com/compare/miro-vs-pen-dev.md): B 65 vs D 47.6 - [pen.dev vs Penpot API + MCP](https://www.anchorterminal.com/compare/pen-dev-vs-penpot.md): D 47.6 vs E 43.5 - [Melius vs pen.dev](https://www.anchorterminal.com/compare/melius-vs-pen-dev.md): C 54.1 vs D 47.6 ## Verify this listing For the vendor.
