atlas-graph-query

A thin reference for the Atlas knowledge-graph MCP tool surface so any agent (including sub-agents) can query the graph without re-deriving conventions. The server URL is wired natively by the atlas plugin and is overridable via ATLAS_MCP_URL. Never invent node ids — only use ids returned by these tools.

Position: this is the SECONDARY / enrichment layer. The atlas plugin is scan-first — it inventories your REAL systems by scanning your actual sources (Azure via read-only az, git repos, local directories) and process/data mining them. The graph queries below are used ONLY to add best-practice / comparison context to those already-discovered real systems. Do NOT use the graph as the primary content, and never pad a real inventory with generic catalog nodes. Tie every graph lookup back to a real scanned system.

Tools

mcp__atlas__atlas_public_search

Full-text/semantic search over the graph. Key params: q (query), optional kind filter, limit. Prefer it to find seed/anchor nodes from need terms.

mcp__atlas__atlas_public_record

Fetch one node's full record by id (fields + edges). Use expandNeighbors to pull immediate relations in one call. Prefer it to read detail once you have ids.

mcp__atlas__atlas_public_neighbors

Traverse the graph from a node. Key params: id, depth, edges (edge-kind filter), kinds (node-kind filter). Prefer it to expand a subsystem from anchors.

mcp__atlas__atlas_public_kinds

List all node kinds in the graph. Use to scope a domain to relevant kinds.

mcp__atlas__atlas_public_kind

Describe a single node kind (schema/fields). Use before relying on a kind's shape.

mcp__atlas__atlas_public_edge_kinds

List all edge kinds. Use to understand how nodes relate.

mcp__atlas__atlas_public_edge_kind

Describe a single edge kind. Use to interpret a specific relation type.

mcp__atlas__atlas_public_clusters

List graph clusters (thematic groupings). Use to scope a domain to cluster(s).

mcp__atlas__atlas_public_stats

Graph-level counts/metrics. Use for sizing and sanity checks.

mcp__atlas__atlas_public_wiki_page

Fetch a narrative wiki page for context. Use to capture human-readable nuance.

Query recipes

• Find by need — atlas_public_search(q=<need terms>) → take top ids.
• Expand a subsystem — atlas_public_neighbors(id, depth=2, kinds=[...]).
• Inspect a node — atlas_public_record(id, expandNeighbors=true).
• Browse a cluster — atlas_public_clusters → pick cluster → search/ neighbors scoped to it.
