Tools & Skills

MCP tools for graph operations and skills for procedural guidance.

How it works: External agents call MCP tools to read and write your graph. Contexts are optional soft organization only; node quality should come from clear nodes and explicit edges.

MCP Tools

RA-OS exposes these core standalone MCP tools:

Context + Graph

Tool	Description
`getContext`	Graph overview: stats, contexts, hub nodes, recent activity, skills
`queryNodes`	Search nodes by keyword/date/context
`getNodesById`	Fetch full nodes by ID
`createNode`	Create a node
`updateNode`	Update a node
`createEdge`	Create an edge between nodes
`queryEdge`	Query edges
`updateEdge`	Update edge explanation
`queryContexts`	List contexts and optional attached nodes

Skills + Search

Tool	Description
`listSkills`	List available skills
`readSkill`	Read one skill
`writeSkill`	Create/update a skill
`deleteSkill`	Delete a skill
`searchContentEmbeddings`	Search source chunks/transcripts
