RAG Query — Personal Knowledge Graph

Query your personal LightRAG knowledge graph to recall decisions, preferences, project context, and learnings from past sessions.

Query Modes

Mode	When to use	What it does
`hybrid` (default)	Most queries	Combines local entity relationships + global topic summaries
`local`	"What's related to X?"	Traverses entity relationships from specific nodes
`global`	"What do you know about topic Y?"	Summarizes across all documents on a topic
`naive`	Simple keyword lookup	Basic text search, fastest but least intelligent

How to query

Full query (returns answer)

node -e "
const BASE = process.env.LIGHTRAG_SERVER_URL || 'http://YOUR_LIGHTRAG_HOST:YOUR_PERSONAL_PORT';
(async () => {
  const auth = await fetch(BASE + '/auth-status').then(r => r.json());
  const token = auth.access_token;
  const res = await fetch(BASE + '/query', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': 'Bearer ' + token
    },
    body: JSON.stringify({
      query: 'QUERY_HERE',
      mode: 'hybrid'
    })
  });
  const data = await res.json();
  console.log(JSON.stringify(data, null, 2));
})();

Context-only query (returns raw context for Claude to synthesize)

node -e "
const BASE = process.env.LIGHTRAG_SERVER_URL || 'http://YOUR_LIGHTRAG_HOST:YOUR_PERSONAL_PORT';
(async () => {
  const auth = await fetch(BASE + '/auth-status').then(r => r.json());
  const token = auth.access_token;
  const res = await fetch(BASE + '/query', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': 'Bearer ' + token
    },
    body: JSON.stringify({
      query: 'QUERY_HERE',
      mode: 'hybrid',
      only_need_context: true
    })
  });
  const data = await res.json();
  console.log(typeof data === 'string' ? data : JSON.stringify(data, null, 2));
})();

Response format

When presenting results to the user:

Be concise — summarize, don't dump raw JSON
Cite the source type when relevant (e.g., "from a stored decision on 2026-03-15")
Flag potentially stale information (anything >30 days old)
If no results found, say so clearly — don't fabricate

Infrastructure

Server: YOUR_LIGHTRAG_HOST:YOUR_PERSONAL_PORT
Auth: Bearer token from /auth-status (guest/disabled mode)
Env var: LIGHTRAG_SERVER_URL
