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).

"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

Check if SilverBullet is running: curl http://localhost:3000/.ping
Verify SILVERBULLET_URL is set correctly
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

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