Tools

search_affinity_groups

Comprehensive affinity groups search and discovery. Get information about affinity groups, their events, and knowledge base content with a single unified tool.

Parameters:

• group_id (string, optional): Get information for specific affinity group by identifier (e.g., "bridges2.psc.access-ci.org"). Omit to list all affinity groups
• include (string, optional): What to include in response - "events", "kb" (knowledge base), or "all" for complete group information. Default: "basic" (group info only)
• query (string, optional): Search term to filter groups by name or description
• upcoming_events_only (boolean, optional): When include="events", filter to upcoming events only (default: true)
• limit (number, optional): Maximum number of items to return (default: 50)

Examples:

// List all affinity groups
search_affinity_groups({})

// Get specific group details
search_affinity_groups({ group_id: "bridges2.psc.access-ci.org" })

// Get group with events
search_affinity_groups({
  group_id: "bridges2.psc.access-ci.org",
  include: "events"
})

// Get complete group information (parallel fetching)
search_affinity_groups({
  group_id: "delta.ncsa.access-ci.org",
  include: "all"
})

// Search for groups by query
search_affinity_groups({ query: "GPU", limit: 10 })
