Charming bronze

“Charming hosts personal interactive web apps for agents. Each app has a real URL, persistent KV storage, and an HTTP/MCP API. Agents can build, update, share, query, and iterate on apps across sessions and across surfaces (ChatGPT, Claude, code editors). Interaction is via MCP (see `url`) or the HTTP API documented at https://charm.ing/.well-known/openapi.json — Charming does not currently expose an A2A JSON-RPC endpoint.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of usecharming.com controls every word below.

Build a new app

Author an interactive web app or start from a published one. Existing-contract saves return a live URL; ESM saves return a build ID to inspect or cancel before publication. Backed by MCP tools `create_app`, `update_app`, `get_app_build`, `cancel_app_build`, and `search_templates`.

createbuildscaffold
Examples it gives
  • Build me a daily mood tracker.
  • Create an app that tracks my reading list.

List and inspect apps

List the caller's apps, fetch source/metadata, rename, and delete. Backed by `list_apps`, `get_app`, `get_app_source`, `rename_app`, `delete_app`.

listinspectmanage
Examples it gives
  • Show me all my Charming apps.
  • Rename my protein tracker to nutrition log.

Call an app's operations

Read or mutate an app's stored state via the operations it declares. Backed by `query_app`, `mutate_app`, `upload_asset`.

callquerymutate
Examples it gives
  • Log today's meal in my food tracker.
  • What is currently on my reading list?

Share apps and publish templates

Share an app with collaborators, end users, or viewers, manage shares, open it to anyone with the link, and configure whether it is a template + starter prompt. Backed by `share_app`, `unshare_app`, `list_app_shares`, `set_public`, `unset_public`, `set_template`, `unset_template`, `set_starter_prompt`, and the deprecated aliases `set_remixable` / `unset_remixable`.

Examples it gives
  • Share my workout tracker with alice@example.com.

Capture feedback from inside an app

Record per-app feedback — bug reports, feature requests, missing capabilities — and read the Charming team's replies. Backed by `submit_feedback`, `list_feedback`, `list_feedback_responses`, `acknowledge_feedback_responses`.

feedbackreport
Examples it gives
  • Report that the date picker is broken in my journal app.

Read Charming documentation

Read the public Charming docs over the same connection, with no web access: the index, a capability or reference page, or the full authoring manual. Backed by `read_docs`.

docsreferenceread
Examples it gives
  • How do I add storage to a Charming app?
  • Read the Charming design guide before building my app.

Run an app on a schedule

Run one of an app's own operations on an hourly, daily, or weekly timer with no chat open, and manage those schedules. Backed by `create_routine`, `list_routines`, `update_routine`, `delete_routine`.

  • Refresh my dashboard data every morning.
  • Turn off the weekly digest on my reading list app.
