Crewhu

Crewhu MCP Server

A Model Context Protocol (MCP) server for Crewhu — customer feedback, employee engagement, and gamification platform. Enables AI assistants to manage surveys, badges, prizes, and user engagement data.

This is a Model Context Protocol (MCP) server that connects Claude (or any MCP-compatible AI) to your Crewhu environment.

Part of the [MSP Claude Plugins](https://github.com/WYRE-AI) ecosystem — a growing suite of AI integrations for the MSP stack. Built by MSPs, for MSPs.

Installation

npm install @wyre-ai/crewhu-mcp

Configuration

Copy .env.example and set the variables below. Leave CONDUIT_S2S_SECRET empty in that file.

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

HTTP authentication

With MCP_TRANSPORT=http and a real CONDUIT_S2S_SECRET, every /mcp request must include X-Gateway-S2S. A missing or invalid header returns 401 before any vendor credential is read.

The header is an HMAC proof:

X-Gateway-S2S: t=<unix seconds>,v1=<hex hmac-sha256>

v1 is the hex-encoded HMAC-SHA256 of the ASCII string t= (the same t= prefix and value), keyed with CONDUIT_S2S_SECRET. The timestamp must be within 300 seconds of the server clock.

t=$(date +%s)

sig=$(printf 't=%s' "$t" | openssl dgst -sha256 -hmac "$CONDUIT_S2S_SECRET" -hex | awk '{print $NF}') curl -sS "http://127.0.0.1:8080/mcp" \ -H "X-Gateway-S2S: t=${t},v1=${sig}" \ -H "X-Crewhu-Api-Token: $CREWHU_API_TOKEN" \ -H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

In AUTH_MODE=gateway, /mcp also requires X-Crewhu-Api-Token. A missing or blank header returns 401 and does not fall back to CREWHU_API_TOKEN.

Usage

Running with Claude Desktop

Add to your Claude Desktop claude_desktop_config.json:

{

"mcpServers": { "crewhu-mcp": { "command": "npx", "args": ["@wyre-ai/crewhu-mcp"], "env": { "CREWHU_API_TOKEN": "your-crewhu-api-token" } } } }

Running with Claude Code (CLI)

claude mcp add crewhu-mcp \

-e CREWHU_API_TOKEN=your-value \ -- npx -y @wyre-ai/crewhu-mcp

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 a real S2S secret. In gateway mode, the Crewhu token arrives on each request as X-Crewhu-Api-Token; it is not read from the environment. Startup exits if CONDUIT_S2S_SECRET is empty or a known placeholder.

docker build -t crewhu-mcp .

docker run \ -e CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \ -p 127.0.0.1:8080:8080 \ crewhu-mcp

Compose refuses to start when CONDUIT_S2S_SECRET is unset, defaults AUTH_MODE to gateway, publishes 127.0.0.1:8080:8080, and does not set CREWHU_API_TOKEN:

CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" docker compose up

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

docker run \

-e CONDUIT_S2S_SECRET="$CONDUIT_S2S_SECRET" \ -e AUTH_MODE=env \ -e CREWHU_API_TOKEN=your-value \ -p 127.0.0.1:8080:8080 \ crewhu-mcp

Local HTTP without a secret is development-only. It binds 127.0.0.1 only and logs a warning. A non-loopback MCP_HTTP_HOST is ignored:

MCP_TRANSPORT=http MCP_ALLOW_INSECURE_DEV=1 npm start
