To interact with the workspace GraphRAG knowledge graph, use the `workflow.graphrag.*` REPL command namespace via `mcpserver-repl --agent-stdio`. GraphRAG combines graph-based retrieval with semantic search, enabling richer context retrieval than vector-only approaches.
To interact with the workspace GraphRAG knowledge graph, use the workflow.graphrag.* REPL command namespace via mcpserver-repl --agent-stdio. GraphRAG combines graph-based retrieval with semantic search, enabling richer context retrieval than vector-only approaches.
GraphRAG is disabled by default. Confirm it is active for the workspace before calling any operations — workflow.graphrag.status will report enabled: false if it has not been configured.
To inspect whether GraphRAG is enabled, initialized, and indexed for the active workspace:
type: request
payload:
requestId: req-20260409T120000Z-status-001
method: workflow.graphrag.status
params: {}
type: result
payload:
requestId: req-20260409T120000Z-status-001

Key state values: disabled, uninitialized, idle, indexing, indexed, error.
To rebuild the GraphRAG index from the current corpus:
type: request
payload:
requestId: req-20260409T120001Z-index-001
method: workflow.graphrag.index
params:
force: false
Set force: true to rebuild even when no corpus changes are detected. The response reports the post-index status including whether the job was started immediately or queued.
To run a natural-language query against the indexed graph:
type: request
payload:
requestId: req-20260409T120002Z-query-001
method: workflow.graphrag.query
params:
query: What authentication mechanisms does the system support?
mode: local
maxChunks: 10
includeContextChunks: true
maxEntities: 20
maxRelationships: 20
communityDepth: 2
responseTokenBudget: 2000
Valid mode values:
local — focuses on directly relevant entities and their immediate relationships; lower latencyglobal — traverses community structure for broad thematic answers; higher coveragedrift — follows conceptual drift to surface related but non-obvious connectionsAll params except query are optional. The result includes an answer, source citations, and optionally the raw chunks, entities, and relationships used:
type: result
payload:
requestId: req-20260409T120002Z-query-001
result:
query: What authentication mechanisms does the system support?
mode: local
answer: |
The system supports API key authentication via the X-Api-Key header,
workspace-scoped token rotation on server restart, and HMAC-SHA256
marker signature verification for agent bootstrap.

JWT Authentication Design
The token service uses HS256 symmetric signing with a 256-bit workspace key.
Tokens expire after 1 hour. Refresh tokens use RS256 and expire after 30 days.
The JwtValidator class validates token signatures and extracts claims.

Common error codes for GraphRAG operations:
graphrag_disabled — GraphRAG is not enabled for this workspacegraphrag_not_indexed — corpus exists but has not been indexed yet; call index firstdocument_not_found — no document with the specified IDentity_not_found — no entity with the specified IDrelationship_not_found — no relationship with the specified IDingestion_error — text could not be chunked or storedindex_error — indexing operation failed; check status for lastErrorTo add new knowledge and make it immediately queryable:
workflow.graphrag.status to verify GraphRAG is enabled: true and isIndexed: trueworkflow.graphrag.ingest with the raw text; set triggerReindex: false for batch ingestionworkflow.graphrag.entities.create to add curated entities from the textworkflow.graphrag.relationships.create to link new entities to existing onesworkflow.graphrag.index with force: false once all documents are ingestedworkflow.graphrag.query with mode: local to verify the new knowledge is retrievableFor large ingestion batches, ingest all documents first, then trigger a single index call at the end to minimize total indexing time.
