GraphQL
Build product, inventory, order, and operations screens over the same command-backed graph the console uses.
Explore GraphQLDevelopers
Build against the contract the operator console uses.
GraphQL for reads and writes. MCP for AI agents. A first-party CLI for inspection. Every action leaves a receipt you can replay. Build once and reuse the same shape across surfaces.
Reference system
Every developer surface resolves to one trusted source.

Surfaces
Hosted surfaces, one operating contract.
MCP tools
Give trusted agents typed tools for reads, previews, approvals, and governed actions without screen scraping.
Explore MCPkf CLI
Use `kf` for terminal inspection, local bootstrap bundles, focused operator workflows, and receipt-friendly JSON.
Open CLI guideCommand registry
State changes enter as typed commands with policy, idempotency, events, and receipts attached.
See command modelEvents and webhooks
Subscribe downstream systems to signed operational events with retries, redrive, and audit evidence.
Verify webhooksAgents
Connect external and first-party agents through the same API, MCP, approval, and receipt boundaries as people.
Explore agentsControls
Approvals, receipts, and guides stay beside the APIs.
Schema explorer
Open the GraphiQL v4 surface wired for the configured read-only endpoint. Until that endpoint is published for your cell, use it alongside the static reference.
Open explorerSchema map
Visual graph of every entity, query, mutation, and type. It introspects the configured endpoint when available and falls back gracefully when the endpoint is offline.
Open schema mapConnectors as modules
Source and Destination connector packages share manifest, RBAC, rate limits, and audit. Build one, inherit the rest.
Open connector surfaceTraceability
Canonical KarmanFlow correlation IDs, W3C trace context, GraphQL reports, MCP reports, and partner header rules.
Open trace guideApprovals + receipts
High-risk actions bind approval context before execution. Every command leaves a typed receipt you can replay.
Open approvals surfaceEvent catalog
Every domain event is named, versioned, and registered. Webhooks and the relay subscribe to the same catalog.
Open event catalogUniversal Commerce Protocol
Documented .well-known/ucp discovery with standard dev.ucp catalog aliases, canonical cart and checkout model coverage, extension UI metadata, and tenant-bound signatures for preview cells that enable it.
Open UCP surfaceWebhooks (Standard Webhooks v1)
HMAC-SHA256 signed deliveries with replay protection, idempotent webhook-id, 8-attempt fixed backoff, secret rotation with overlap, and ReplayWebhookDelivery for redrive.

Reference pages stay aligned with sandbox-proven contracts.
GraphQL, MCP, CLI, webhooks, commands, agents, and skills share one command and receipt boundary.
Hosted references stay aligned with the sandbox-proven contracts, including schema map, explorer, CLI help, trace reports, and webhooks.
Use the quickstart with hosted preview credentials, then move into reference pages for exact flags and payloads.
Get started
Five steps to a working preview tenant.
The quickstart walks through access, tenant setup, seeded demo data, and your first inspection through the CLI. The shape mirrors the hosted preview environment.
