Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

Capabilities

Tools 4

get_app

Get one app from the Spark catalogue by its id, with its full description, tags and links. Read-only. If the id is unknown the result lists every valid id, so there is no need to guess twice.

Discovered
list_apps

List every app in the Spark catalogue: id, name, tagline, description, tags, homepage and store or repository links. Read-only. Small enough to read in full, so prefer this over search when the question is about the range of apps rather than a specific one.

Discovered
list_tags

List every tag used across the Spark catalogue with how many apps carry it, most used first. Read-only. Use this before search_apps to pick a tag that actually exists.

Discovered
search_apps

Search the Spark catalogue by keyword across app names, taglines, descriptions and tags, optionally narrowed to a single tag. Read-only. Pass an empty query with a tag to list everything carrying that tag.
