Reviewer Notes

Val Town has decent documentation and a free tier with a sandboxed environment, making it discoverable and experimentally accessible. However, it lacks critical agent infrastructure: no MCP server, no OpenAPI spec, and no programmatic account creation (OAuth2 only, requires browser interaction). The API for creating and managing vals is underdocumented for agents, and there's no clear structured interface for agents to deploy code autonomously. The platform itself is reliable, but the friction around authentication and lack of agent-native tooling significantly limit autonomous integration.
