Local Playgrounds Info

[MODE:BROWNFIELD] Read-only, idempotent. Tier: local.

Returns local Playground names, URLs, source mounts, or full metadata from the local Marquee filesystem. No Rails API call.

When to use

• Discover local Playgrounds with view:"names".
• Discover service URLs with view:"urls".
• Discover per-service source mount paths with view:"mounts".
• Confirm a local Playground's compose project name / paths.
• Pre-flight before fibe_local_playgrounds_link to verify the target.
• Mapping a name to its mount directory for ad-hoc shell debugging.

Inputs

Field	Type	Required	Notes
view	string	yes	names, urls, mounts, or details
playground	string	conditional	Local playground ID, name, compose project, playspec, or unique playspec prefix. Omit for view:"names"
playground_id	number	conditional	Local numeric Playground ID. Omit for view:"names". Pass either playground or playground_id, not both

Output

Native structured MCP data, not a cobra stdout envelope.

view:"names":

[{ "id": "42", "name": "demo-app--42", "playspec": "demo-app", "path": "/opt/fibe/playgrounds/demo-app--42" }]

view:"urls":

[{ "service": "web", "url": "web.phoenix.test" }]

view:"mounts":

[{ "service": "web", "mount": "/opt/fibe/playgrounds/demo-app--42/props/acme--demo-app/main", "prop": "demo-app", "branch": "main" }]

view:"details" returns the full local Playground object with service metadata.

Gotchas

• view:"names" does not accept a target selector.
• urls, mounts, and details require one target selector.
• Numeric selectors match the local compose project suffix (<name>--<id>), not a Rails query.
• Ambiguous playspec prefixes return an error listing candidates.
• Filesystem-only — local data may be stale if the Playground has been remotely deleted.
