Silverbullet MCP MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. This project provides a Model Context Protocol (MCP) server that acts as a bridge to your SilverBullet instance. It enables Large Language Models (LLMs) and other MCP-compatible clients to interact with your.
Once Silverbullet MCP is connected, these are the calls the assistant has available:
SB_AUTH_TOKEN — A secure token for SilverBullet to authenticate with this MCP server and for this MCP server to authenticate with SilverBulletMCP_TOKEN — A secure token for clients (e.g., your AI model) to authenticate with this MCP serverSB_API_BASE_URL — (Optional if running via docker-compose as defined) The base URL for the SilverBullet API. Defaults to http://silverbullet:3000 in thePORT — (Optional if running via docker-compose as defined) The port the MCP server will listen on. Defaults to 4000Example — http://localhost:4000/mcp?token=YOUR_MCP_TOKENYou will need 4 environment variables: MCP_SERVER_TOKEN, SB_AUTH_TOKEN, SB_API_BASE_URL, YOUR_MCP_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Installation goes through your MCP client rather than a global install: point it at mcp-remote on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
This sits in the cloud and infrastructure group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Silverbullet MCP's toolset — SB_AUTH_TOKEN, MCP_TOKEN, SB_API_BASE_URL and 2 more — is a fair guide to whether it matches your workflow. It is maintained by Ahmad-A0; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Silverbullet MCP's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
| Tool | What it does |
|---|---|
| SB_AUTH_TOKEN | A secure token for SilverBullet to authenticate with this MCP server and for this MCP server to authenticate with SilverBullet. |
| MCP_TOKEN | A secure token for clients (e.g., your AI model) to authenticate with this MCP server. |
| SB_API_BASE_URL | (Optional if running via docker-compose as defined) The base URL for the SilverBullet API. Defaults to http://silverbullet:3000 in the docker-compose.yml. |
| PORT | (Optional if running via docker-compose as defined) The port the MCP server will listen on. Defaults to 4000. |
| Example | http://localhost:4000/mcp?token=YOUR_MCP_TOKEN |
