Run

Node.js 22+.

npm ci
npm run dev
npm test
npm run typecheck
npm run build

Public MCP endpoint: https://mcp.edenbuilds.me/mcp. Tools: accord_describe, accord_evaluate. No upstream business systems are connected to this endpoint.

Local gateway

export ACCORD_GATEWAY_TOKEN="$(openssl rand -hex 32)"
npm run gateway

Configure your MCP client for http://127.0.0.1:4318/mcp with its secure bearer-header configuration. The default gateway/example.json forwards to the public read-only preview. Override ACCORD_CONFIG for another configuration file. Upstream credentials are environment references via tokenEnv; do not commit credentials. Policies use namespaced exact tool names.

Boundaries

The public site is a developer preview, not a hosted enterprise service. Hosted tenancy, durable quotas, OAuth brokering, billing, persistent approvals/audit export, semantic caching, fleet management, and compliance assurance are planned. The local gateway is single-process, loopback-only, and designed for trusted evaluation upstreams. Its counters reset on restart. Workbench samples are fictional and labeled. No model is called.

See security and the full strategy before extending the gateway.
