Common questions

Is Val Town safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Vexa, emailmd, MCP WhatsApp Cloud

Agent plugins for Val Town

Installs the Val Town MCP server and Skills for Claude Code, Codex, and Cursor.

Skills are markdown files with platform guidance for building on Val Town. Used by Val Town's own tools (Townie, the MCP server) and by AI coding agents. Skills include HTTP vals, crons, SQLite, email, OAuth, frontend, and API integrations.

Install

Installing the plugin makes platform skills available to your agent and registers the hosted Val Town MCP server (https://api.val.town/v3/mcp). On first use of an MCP tool, the agent runs the OAuth flow in your browser.

Claude Code
Codex
Cursor

Claude Code

Install the Val Town plugin by running:

claude plugin install valtown@claude-plugins-official

Codex

`codex` CLI

First, run:

codex plugin marketplace add val-town/plugins

Then fire up codex and run:

/plugins

Search for Val Town, hit install, and it'll take you through the OAuth path.

Codex desktop app

Click "Plugins" in the sidebar
In the dropdown that says "Built by OpenAI" click "Add more +"
Copy-paste https://github.com/val-town/plugins and select "Add marketplace"

Cursor

In Cursor, run:

/add-plugin valtown

Or in Cursor Settings, copy-paste https://github.com/val-town/plugins in the search box and select "Add to Cursor."

Authoring skills

Skills live in plugin/skills/ /SKILL.md with YAML frontmatter:

---

name: http-endpoints description: Use when building an HTTP val — a web endpoint, API route, webhook... triggers: [http, endpoint, webhook, api, request, response]

HTTP Endpoints

...guide body...

name (required) — must match the directory name; lowercase, hyphens, ≤64 chars.
description (required) — written as "Use when…"; this is how Claude decides to load the skill. ≤1024 chars.
triggers (optional) — keyword hints that boost searchSkills ranking; ignored by Claude Code's native loader.

Keep content audience-neutral: only platform knowledge true for every consumer. No product-flow or chat-only advice.

Then build:

npm install

npm run build # generate src/generated/skills.ts, then tsc npm test # build + smoke tests

npm run generate validates every skill against both our schema and Claude Code's frontmatter constraints — a skill that wouldn't load in Claude Code fails the build.

Relationship to the Val Town monorepo

This package is the source of truth for skill content. The Val Town app and MCP server consume it as a dependency rather than holding their own copy. See docs/SKILLS_PLUGIN.md in the main repo for the full design.

Versioning

This repository uses Changesets for publishing. See their documentation for more information.

For each change that should trigger a new version, you should run npx @changesets/cli and fill out the interactive prompts to describe the changes. This will generate a new changeset in the .changesets directory.
Each change in that directory will prompt the release.yml GitHub action to create a new release PR.
Merging a release PR will automatically publish a new version of this module.

Configuration

Claude Code

The official Claude plugin marketplace pulls from .plugins/marketplace.json.

Codex

Codex reads the native marketplace at .agents/plugins/marketplace.json (and falls back to the Claude .claude-plugin/marketplace.json for compatibility).

Cursor

Cursor reads .cursor-plugin/marketplace.json and the per-plugin plugin/.cursor-plugin/plugin.json.
