Deterministic decision engine with receipts. Define rules in YAML, query a graph, get proof.
Connect Cruxible to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Deterministic decision engine with receipts. Define rules in YAML, query a graph, get proof. The cruxible mcp server is what makes that connection.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
incident_impacts_supplier — Incident -> Supplierrelationship — incident_impacts_supplierError — DirectWriteRefusedError: Direct write to relationshipPer — type write_policy chooses direct, proposal-only, or mint-only admission;Prompted — EnforcedLayer — JobCruxible — Maintain claim lifecycle, execute exact reads and bounded actions, enforce policy, and attach receipts and outcomesKit — KindThe server ships on PyPI as cruxible, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Cruxible's toolset — incident_impacts_supplier, relationship, Error and 5 more — is a fair guide to whether it matches your workflow. It is maintained by cruxible-ai; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
