Dicker Data

Dicker Data MCP Server

MCP server for Dicker Data's B2B partner/reseller REST API - pricing and stock lookup, order placement and tracking, and invoices, for AI assistants and the WYRE Conduit gateway.

Authentication

Dicker Data does not offer self-serve API signup. Request access from [email protected] or [email protected] to receive a long-lived AccountCode + AccessToken pair.

Every real API call additionally requires a short-lived AccessKey, obtained by exchanging the AccountCode/AccessToken via POST /api/AccessKeyRequest. This server handles that exchange (and its refresh, on expiry) internally - callers only ever need to supply the long-lived credentials.

Configuration

Copy .env.example and set the variables below.

Variable	Required	Description
DICKERDATA_ACCOUNT_CODE	For stdio and AUTH_MODE=env	Long-lived account code issued by Dicker Data. Gateway mode does not read this.
DICKERDATA_ACCESS_TOKEN	For stdio and AUTH_MODE=env	Long-lived access token issued by Dicker Data. Gateway mode does not read this.
MCP_TRANSPORT	No	stdio (default) or http.
AUTH_MODE	No	gateway (Docker image and Compose default) or env. Gateway mode requires X-DickerData-Account-Code and X-DickerData-Access-Token on each /mcp request and never falls back to DICKERDATA_*. env uses those variables after S2S auth succeeds.
CONDUIT_S2S_SECRET	Yes for HTTP	Service-to-service secret. The HTTP server logs an error and exits non-zero when this is empty or a known placeholder. Compose will not start without it. Never commit a real value.
MCP_ALLOW_INSECURE_DEV	No	Set to exactly 1 only for local development to start HTTP without CONDUIT_S2S_SECRET. The process logs a warning, does not enforce X-Gateway-S2S, and binds 127.0.0.1 only. A non-loopback MCP_HTTP_HOST is overridden and logged. A placeholder secret still refuses to start.
MCP_HTTP_HOST	No	Bind address when a secret is configured. Unset means 0.0.0.0. The container image sets 0.0.0.0. Ignored in favor of 127.0.0.1 when the insecure-dev bypass is on.
MCP_HTTP_PORT	No	HTTP port. Defaults to 8080.
LOG_LEVEL	No	debug, info (default), warn, or error.

/health stays unauthenticated, does not require X-Gateway-S2S, and does not read vendor credentials. The stdio transport does not use CONDUIT_S2S_SECRET.

HTTP authentication

With MCP_TRANSPORT=http and CONDUIT_S2S_SECRET set, every /mcp request must include X-Gateway-S2S. The value is t=<unix seconds>,v1=<hex hmac-sha256>. The hex digest is HMAC-SHA256 over the exact ASCII string t=<unix seconds> (the same prefix that appears in the header), keyed with CONDUIT_S2S_SECRET, encoded as 64 lowercase hex characters. The timestamp must be within 300 seconds of the server clock. A missing or invalid header returns 401. The secret is never written to logs or the response.

X-Gateway-S2S: t=1710000000,v1=<64 lowercase hex chars>

Known placeholders are rejected at startup and do not count as a configured secret: changeme, change-me, secret, example, placeholder, replace-me, your-secret, your-s2s-secret, s2s-secret, replace-with-a-real-secret. Generate a value with openssl rand -hex 32.

In AUTH_MODE=gateway, /mcp also requires X-DickerData-Account-Code and X-DickerData-Access-Token. Those headers are the only Dicker Data credentials for that request. A request missing either returns 401 and does not fall back to DICKERDATA_ACCOUNT_CODE / DICKERDATA_ACCESS_TOKEN.

• dickerdata_get_invoice_details - line-item detail for a sales order/invoice.

Scope

This is a v1 / MVP surface covering the core distributor workflow (pricing, ordering, tracking, invoicing). Explicitly out of scope for now: Microsoft CSP/ESD subscription management, Autodesk subscriptions, and annuity-order endpoints - these are much larger, vendor-specific surfaces distinct from core distribution. They can be added as a follow-up if there's demand.

Development

npm install
npm run build
npm test
npm run lint   # tsc --noEmit

Docker

The image listens on 0.0.0.0 inside the container (MCP_HTTP_HOST) and defaults to AUTH_MODE=gateway. Publish the port on loopback and pass the S2S secret. In gateway mode the account code and access token arrive on each request as X-DickerData-Account-Code and X-DickerData-Access-Token; they are not read from the environment.

docker build -t dicker-data-mcp .
docker run \
  -e CONDUIT_S2S_SECRET="$(openssl rand -hex 32)" \
  -p 127.0.0.1:8080:8080 \
  dicker-data-mcp

Do not pass a known placeholder such as your-s2s-secret or changeme. Startup treats those as unset and exits. Compose refuses to start when CONDUIT_S2S_SECRET is unset, sets AUTH_MODE=gateway, does not pass DICKERDATA_ACCOUNT_CODE or DICKERDATA_ACCESS_TOKEN, and publishes 127.0.0.1:8080:8080. A project .env is interpolation only — do not add env_file to the gateway service.

CONDUIT_S2S_SECRET="$(openssl rand -hex 32)" docker compose up

Single-tenant HTTP (AUTH_MODE=env) still requires the S2S secret, then uses DICKERDATA_ACCOUNT_CODE and DICKERDATA_ACCESS_TOKEN:

docker run \
  -e CONDUIT_S2S_SECRET="$(openssl rand -hex 32)" \
  -e AUTH_MODE=env \
  -e DICKERDATA_ACCOUNT_CODE=your-account-code \
  -e DICKERDATA_ACCESS_TOKEN=your-access-token \
  -e MCP_HTTP_HOST=0.0.0.0 \
  -p 127.0.0.1:8080:8080 \
  dicker-data-mcp

Local HTTP without a secret is development-only. It binds 127.0.0.1 and logs a warning. A non-loopback MCP_HTTP_HOST (including 0.0.0.0) is overridden and that override is logged:

MCP_ALLOW_INSECURE_DEV=1 npm run start:http

A signed gateway request:

curl -sS http://127.0.0.1:8080/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -H "x-gateway-s2s: $X_GATEWAY_S2S" \
  -H "x-dickerdata-account-code: $DICKERDATA_ACCOUNT_CODE" \
  -H "x-dickerdata-access-token: $DICKERDATA_ACCESS_TOKEN" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
