**One-click deployment to Cloudflare Workers** - Sets up your own free MCP server instance in under 2 minutes.
## Tools Overview
Current active tools:
1. **get_exact_scripture** - Fetch an exact LDS scripture verse or short contiguous range
- **reference** (string, required): A verse or short range like "John 3:16", "Alma 32:27-28", "1 Nephi 3:7". Range limit: ≤50 verses.
- **Fuzzy matching supported**: "Matt 5:16" → "Matthew 5:16", "Omni 7" → "Omni 1:7", "Doc 121" → "D&C 121"

### 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:
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:
```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)**
[](https://deploy.workers.cloudflare.com/?url=https://github.com/adammharris/gospel-library-mcp)
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.

### Future Enhancements (Ideas)
* Ranking improvements or FTS.
* Citation generation referencing talk paragraphs.
* Caching of frequent queries.
* Footnotes
* Optionally allow for web scraping
* More resources from Gospel Library
