Error / Guidance Messages

The tools return actionable hints when no results are found, suggesting alternative search approaches or parameter adjustments.

Local Development

Type check:

bun run type-check

Deploy:

wrangler deploy

Tail logs:

wrangler tail

Local Database Priority (Local -> D1)

At runtime the server resolves the database in this order:

1. Local file gospel-library.db (Node using better-sqlite3 if available, otherwise Bun's built-in sqlite)
2. Cloudflare D1 binding DB (only if no local file connection was established)

Place a SQLite dump named gospel-library.db in the project root to operate entirely offline. The same tools work unchanged.

Connecting a Client

There are two ways to connect to a client: locally and remotely. For developer use, local is recommended. Remote is easier to set up and uses the Cloudflare endpoint.

Local

Example config snippet:

{
  "mcpServers": {
    "gospel-library": {
      "command": "node",
      "args": ["/Users/path/to/repository/dist/stdio-server.js"],
      "env": { "GOSPEL_DB_PATH": "/Users/path/to/database/gospel-library.db"}
    }
  }
}

Remote

Option 1: One-Click Deploy (Recommended)

This will:

1. Fork the repository to your GitHub account
2. Set up a Cloudflare Workers deployment
3. Configure the D1 database automatically
4. Deploy your MCP server instance

Once deployed, use your Worker URL with the /sse endpoint in your MCP client.

Option 2: Manual Deployment

1. Clone this repository
2. Install dependencies: npm install
3. Set up Cloudflare Workers CLI: npm install -g wrangler
4. Login to Cloudflare: wrangler login
5. Create D1 database: wrangler d1 create gospel-library
6. Update database ID in wrangler.jsonc
7. Deploy: wrangler deploy

Option 3: Use Existing Deployment

No authentication is required to use this tool. You will need a client that supports remote MCP servers, such as Claude on a Pro plan or ChatGPT on a Pro plan.
