SilverBullet MCP Server

This skill provides an MCP server for interacting with SilverBullet, a self-hosted markdown-based note-taking app.

Installation

Via ClawdHub

clawdhub install silverbullet

Manual

cd ~/.clawdbot/skills/silverbullet
uv venv
source .venv/bin/activate
uv pip install -e .

Configuration

1. Set SilverBullet URL

export SILVERBULLET_URL="http://localhost:3000"

Or add to your shell profile (~/.zshrc / ~/.bashrc).

2. Configure mcporter

Add to ~/.mcporter/mcporter.json:

{
  "servers": {
    "silverbullet": {
      "command": "python",
      "args": ["{baseDir}/server.py"],
      "transport": "stdio",
      "env": {
        "SILVERBULLET_URL": "http://localhost:3000"
      }
    }
  }
}

Replace {baseDir} with the actual skill path (e.g., ~/.clawdbot/skills/silverbullet).

3. Verify Installation

mcporter list silverbullet

Should show all available tools.

Delete a page

mcporter call silverbullet.delete_page path:"drafts/old-note.md"

Check server status

mcporter call silverbullet.ping_server

Natural Language Examples

Once configured, you can ask Moltbot:

• "List all my SilverBullet pages"
• "Read my index page from SilverBullet"
• "Create a new page called 'Project Ideas' with a list of features"
• "Search for pages containing 'meeting' in the name"
• "Append today's notes to my journal"
• "What's the last modified date of my TODO page?"
• "Is my SilverBullet server running?"

Troubleshooting

Server not responding

1. Check if SilverBullet is running: curl http://localhost:3000/.ping
2. Verify SILVERBULLET_URL is set correctly
3. Check firewall/network settings

Permission denied errors

SilverBullet pages can be read-only. Check the X-Permission header or use get_page_metadata to verify permissions.

Tool not found

1. Verify mcporter config: cat ~/.mcporter/mcporter.json
2. Test server directly: python {baseDir}/server.py (should start without errors)
3. Check Python/uv installation: which python3 uv

{
  "mcpServers": {
    "silverbullet": {
      "command": "python",
      "args": ["/path/to/silverbullet-skill/server.py"],
      "env": {
