MCP Help Article Server

A Model Context Protocol (MCP) server that serves help articles to tenants. Each tenant's AI (Claude) connects to this server and can search and retrieve articles — scoped to shared content + their own tenant-specific content.

MCP Tools Exposed

search_articles

Search help articles by natural language query, scoped to the calling tenant.

{
  "tool": "search_articles",
  "parameters": {
    "query": "how do I reset my password",
    "tenant_id": "acme"
  }
}

get_article

Fetch the full content of a specific article. Access denied if the article belongs to a different tenant.

{
  "tool": "get_article",
  "parameters": {
    "article_id": "shared-001",
    "tenant_id": "acme"
  }
}

Tenant Isolation

Every request must carry a tenant_id. The server returns:

• ✅ All shared articles

• ✅ Articles belonging to the requesting tenant

• ❌ Articles belonging to any other tenant (throws Access Denied)

Data Model

{
  id: "acme-001",
  tenant_id: "acme",       // "shared" | "<tenant_id>"
  title: "...",
  tags: ["onboarding", "crm"],
  content: "Full article text..."
}

How to extend

1. Add articles: Edit data/articles.js — set tenant_id to "shared" or a specific tenant.

2. Add a tenant: Add articles with a new tenant_id — no server changes needed.

3. Swap data source: Replace the in-memory array in data/articles.js with a DB query.

4. Add auth: Validate tenant_id against a JWT/API key before processing any tool call.

Simulate in browser

Open ui/simulator.html in any browser — no server needed. It simulates the full MCP request/response flow in-browser.
