WebMcpExperiments

This application consists of two angular projects:

• The element is a web component
• The shell is the main application and hosts the element.

Both applications register a WebMCP tool (using the @mcp-b/global polyfill) to show an alert.

Next I start the MCP-B Extension in Chrome and invoke one of the two MCP tools. It is actually invoked two times. 😳

I can work around this and skip initialization in the element by commenting out the import:

import '@mcp-b/global'; //initializing this again leads to every tool invocation happening twice.

Now MCP-B is only initialized in the shell and every tool is only invoked once.

I reported this as a bug: https://github.com/WebMCP-org/npm-packages/issues/136

✅ Now this is fixed since version @mcp-b/global@2.0.9.

Development
