mcpnotion

gomcp-tool-notion

Notion tool for the Model Context Protocol

This is a sample MCP server that uses the Notion API to retrieve the content of a Notion page.

The Model Context Protocol SDK being used is the MCP Go SDK.

A description of the go MCP SDK can be found here.

Instructions

configuration file

The configuration file is a JSON file that defines the server information, logging, prompts, and tools.

copy the mcpnotion.json.sample file to mcpnotion.json and edit the values:

• set logging.file to the path where you want to store the log file
• set prompts.file to the path to the prompts.yaml file. There is a sample file at the top of this repository.
• set tools.configuration.notionToken to your Notion token

build the server

Get all the dependencies:

go mod tidy

Build the server:

make

This will create the mcpnotion binary in the bin directory.

integrate with Claude

You need to add your server to the Claude configuration file.

You can easily access this file from the Settings menu in Claude:

Add tour server in the mcpServers section (replace <absolute path> with the actual path to your files):

{
  "mcpServers": {
    "mcpnotion": {
      "command": "<absolute path>/mcpnotion",
      "args": ["--configFile", "<absolute path>/mcpnotion.json"]
    }
  }
}

You MUST restart Claude after adding the server.

Once Claude has restarted, you can check that the server is running by checking the log file you specified in the configuration file.

You can also check in the Claude UI that the server is running by clicking on the icon there:

Your server should appear in the list of Installed MCP Servers:

You can prompt Claude to use your server by mentioning it in your prompt.

For example, you can ask:

Can you summarise the content of the Notion page with the pageId xxxxxxxx?

When Claude is abut to call your function, it will ask you for authorization:

After you grant authorization, Claude will show the parameters of the call and the response from your server in the chat.

prompts access

If you want to access the prompts you have defines in your yaml file, you can access them from Claude:

You will then have a form to fill in the arguments for the prompt.

Note

If you also work on the MCP Go SDK itself, you can add this line to the go.mod file to use your local version of the SDK:

replace github.com/llmcontext/gomcp v0.2.0 => ../gomcp
