  Please refer to the later sections;

• Q: What are some common MCP clients?

  • Refer to: https://github.com/punkpeye/awesome-mcp-clients or https://modelcontextprotocol.io/clients;

• Q: Does the plugin support authentication?

  • Version v0.2.0 now supports authentication. After setting the authentication token in the plugin settings, the MCP client needs to configure the authorization request header with the value Bearer YourToken;

• Q: Can it be used in Docker?

  • No, the plugin relies on a Node.js environment and does not support running on mobile devices or Docker.

    To support SiYuan deployed in Docker, it is recommended to switch to other MCP projects. Some relevant projects may be listed here.

    Alternatively, decouple this plugin from the SiYuan frontend.

How to Configure in an MCP Client?

Different MCP clients require different configuration methods. Please refer to the MCP client documentation.

MCP clients are continuously updated, so the configuration or usage instructions here may not be directly applicable and are for reference only.

Here, we assume: the plugin’s port is 16806, and the authorization token is abcdefg.

Modify the MCP application’s configuration, select the Streamable HTTP type, and configure the endpoint.

Clients Supporting Streamable HTTP

The following configuration uses Cherry Studio as an example. Different MCP clients may require different configuration formats—please refer to the MCP client documentation.

Plugin Without Authorization Token

1. Type: Select Streamable HTTP (streamablehttp);
2. URL: http://127.0.0.1:16806/mcp;
3. Headers: Leave empty;

Plugin With Authorization Token

1. Type: Select Streamable HTTP (streamablehttp);
2. URL: http://127.0.0.1:16806/mcp;
3. Headers: Authorization=Bearer abcedfg;

Clients Supporting Only Stdio

If the MCP client does not support HTTP-based communication and only supports stdio, a conversion method is needed.

Here, we use node.js + mcp-remote@next.

1. Download Node.js: https://nodejs.org/en/download

2. Install mcp-remote@next:

npm install -g mcp-remote@next  

The following configuration uses 5ire as an example. Different MCP clients may require different configuration formats—please refer to the MCP client documentation.

Plugin Without Authorization Token

Command:

npx mcp-remote@next http://127.0.0.1:16806/mcp  

Plugin With Authorization Token

Command:

npx mcp-remote@next http://127.0.0.1:16806/mcp --header Authorization:${AUTH_HEADER}  

Environment Variable:

Name: AUTH_HEADER
Value: Bearer abcdefg
