Error / Guidance Messages
The tools return actionable hints when no results are found, suggesting alternative search approaches or parameter adjustments.
Local Development
Type check: ``bash bun run type-check ``
Deploy: ``bash wrangler deploy ``
Tail logs: ``bash wrangler tail ``
Local Database Priority (Local -> D1)
At runtime the server resolves the database in this order:
- Local file
gospel-library.db(Node using better-sqlite3 if available, otherwise Bun's built-in sqlite) - 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: ``json { "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:
- Fork the repository to your GitHub account
- Set up a Cloudflare Workers deployment
- Configure the D1 database automatically
- Deploy your MCP server instance
Once deployed, use your Worker URL with the /sse endpoint in your MCP client.
Option 2: Manual Deployment
- Clone this repository
- Install dependencies:
npm install - Set up Cloudflare Workers CLI:
npm install -g wrangler - Login to Cloudflare:
wrangler login - Create D1 database:
wrangler d1 create gospel-library - Update database ID in
wrangler.jsonc - 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.
