Feature Request: Selective Tool Loading for Notion MCP

[antonlvovych]

Summary

Add environment variables to enable/disable specific Notion MCP tools at runtime for better security, performance, and reduced context size.

Motivation

Currently all tools load by default. Teams often need only a subset - e.g., read-only agents only need search and fetch. Selective loading reduces token usage, improves security via least-privilege, and simplifies debugging.

Implementation

Environment Variables:

# Allow-list (only these tools load)
ENABLED_TOOLS=search,fetch,create-pages

# or

# Deny-list (everything except these)  
DISABLED_TOOLS=move-pages,duplicate-page,create-comment

Example Usage

Claude Desktop:

{
  "mcpServers": {
    "notion": {
      "command": "npx",
      "args": ["-y", "@notionhq/notion-mcp-server"],
      "env": {
        "NOTION_TOKEN": "ntn_****",
        "ENABLED_TOOLS": "search,fetch,create-pages"
      }
    }
  }
}

Docker:

docker run -e NOTION_TOKEN=ntn_**** \
  -e DISABLED_TOOLS=move-pages,duplicate-page \
  mcp/notion

Benefits

• Smaller schemas = faster discovery + lower token costs
• Least-privilege security for specific workflows
• Easier debugging with minimal tool surface
