LoopGrid components for Langflow.
Drag signed decision evidence into Langflow flows. Record decisions, external actions, outcomes and reviews, then verify the captured evidence through the connected LoopGrid service.
lfx-loopgrid v0.1.0 · Langflow 1.12/LFX extension · Six LoopGrid components.
LoopGrid records evidence only. External nodes or services still execute the consequential business action.
Install the published LFX extension.
pip install lfx-loopgrid==0.1.0 langflow run
Restart Langflow after installation. The LoopGrid bundle should appear in the component palette.
Point components at the same LoopGrid workspace.
defaultA complete six-component flow can use ingest, read and review. Narrower flows should use smaller scopes.
Same evidence contract as Dify and n8n.
Create the decision envelope and proposed action evidence.
Append tool_executed after another component/service performs the action.
Append the authoritative downstream result.
Record approval/rejection when Core is awaiting human review.
Read the lifecycle and signed event history.
Ask the connected LoopGrid service to verify the chain/signatures.
Keep execution separate from evidence.
Agent / model component → LoopGrid Record Decision → policy / approval component → external action component → LoopGrid Record Action → downstream lookup / response → LoopGrid Record Outcome → LoopGrid Verify Decision
Pass the same decision_id through the flow. Do not use LoopGrid as the tool that actually performs the refund, payment or account mutation.
Service verification and offline verification are different checks.
Only map fields that should become evidence. Verification confirms captured integrity/provenance; it does not establish decision correctness or legal compliance.
Make evidence a reusable flow component.
Use the published extension when native Langflow discoverability matters, or use LoopGrid's REST/MCP paths for more generic capture.
