Use agents, where you can select which individual tools to use from an MCP server.

Hi Danny, I tested using agents- used gpt-4o-mini from azureOpenAI for a single query - single action enabled - to navigate to a page

some 21k token got used up in single action and query.

The other agents made from google, openAI and anthropic also give similar response.

I'm experiencing an issue when trying to use the Playwright MCP, the browser_install command is failing with the following error:

Error: Failed to install browser:

WARNING: It looks like you are running 'npx playwright install' without first installing your project's dependencies.                                       To avoid unexpected behavior, please install your dependencies first, and then run Playwright's install command:                                        
npm install
npx playwright install

If your project does not yet depend on Playwright, first install the applicable npm package (most commonly @playwright/test), and then run Playwright's install command to download the browsers: 

npm install @playwright/test
npx playwright install

Hi!
I begin by first installing chromium for my application.

command = ["/bin/sh", "-c"]
args = ["apk add --no-cache chromium && node server/index.js"]

So before my application starts I ensure that the browser is installed pre-hand.

That's for the quick reply, @mansiibm! I'll give this a shot.
