## What it does

This server bridges external coding agents with a SilverBullet personal knowledge base. It surfaces tools from the silverbullet-ai extension over MCP, giving assistants like Claude Code and Cursor direct access to space contents.

Execution relies on Node.js 20 or higher. The package runs via `npx` and configures remote access using the `SB_URL` variable, alongside optional `SB_AUTH_TOKEN` and `SB_SPACE_ID` parameters.

A running SilverBullet instance without Runtime API enabled will reject requests. The silverbullet-ai plug must also be installed in the target space, ideally matching the MCP package version.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `SB_URL`, `SB_AUTH_TOKEN`, `SB_SPACE_ID` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

### Claude Code (native platform)

**Platform CLI**
```bash
claude mcp add --env SB_URL=<SB_URL> --env SB_AUTH_TOKEN=<SB_AUTH_TOKEN> --env SB_SPACE_ID=<SB_SPACE_ID> --transport stdio mcp-bridge -- npx -y silverbullet-ai-mcp
```

### Codex

**Platform CLI**
```bash
codex mcp add mcp-bridge --env SB_URL=<SB_URL> --env SB_AUTH_TOKEN=<SB_AUTH_TOKEN> --env SB_SPACE_ID=<SB_SPACE_ID> -- npx -y silverbullet-ai-mcp
```
Replace <…> with your own values

## When to use it
- query SilverBullet notes inside Claude Code and Cursor
- expose silverbullet-ai space actions to MCP-compatible assistants
- configure remote SilverBullet access via environment variables

## Example prompts
- Search my SilverBullet workspace for deployment instructions
- Review the linked notes in my SilverBullet space and outline the next steps
