02 / Tools & web research

Research with Grok.
Change your code with iolys.

Grok works on your solution through the tools supplied by iolys, under your permission mode. Its native Web Search and Fetch URL tools stay available for research.

IOLYS TOOLS

Inspect, change, and validate.

Read and search files, edit code, and run builds and tests. Tool activity and permission requests stay visible in the conversation. Grok’s own file and shell tools are not enabled.

TRY A PROMPT

“Trace this failing integration test across the solution and propose a fix.”

NATIVE WEB TOOLS

Read the source in context.

Ask Grok to search the web or read a public page, such as a migration guide or release note. When a search result arrives without citations, iolys flags it as unverified.

TRY A PROMPT

“Read this library’s migration guide and identify the changes needed in my project.”

See what Grok can use.

Open Tools and Skills beside the prompt. Fetch URL and Web Search appear under the selected Grok model; they cannot be switched off individually.

  • Add the relevant context.Type # to reference a file, or attach the active document or selection.
  • Keep control.Interactive mode asks before Grok edits files or runs commands through iolys.
  • Check what you read.Treat web results as research to verify, especially when they come without citations.

03 / Usage & cost

Follow each turn.
Check your account.

iolys records the token usage and the cost that Grok reports for each turn, and keeps them beside the answer.

  • Reported cost per turn.The conversation shows the USD amount returned by Grok, with input, output, cache, and reasoning tokens in its tooltip.
  • Account usage on request.Open Show usage from the chat toolbar to see the plan and the remaining included allowance when Grok reports it.
  • Missing data stays missing.When Grok does not report an allowance, iolys shows it as unavailable rather than guessing zero or full.

Reported costs are not invoices. Your Grok account remains the reference for allowance, balance, and billing.

Grok and Visual Studio 2026.

Visit the official Grok website ↗
How can I use Grok in Visual Studio for C#?

Install the iolys extension for Visual Studio 2026 and open your C# solution. Open Manage Providers in iolys and add Grok. Install the locally managed Grok Build CLI from the provider panel, then choose Connect and sign in with your Grok account in the browser. Refresh the models, choose a Grok model and a supported effort level, then start from your Visual Studio solution. You can then ask Grok to help with your C# and .NET code from the iolys workspace.

Is there a VSIX extension to use Grok in Visual Studio?

Yes. iolys is a VSIX extension for Visual Studio 2026, and Grok is one of the provider connections it ships with. Install the iolys VSIX once from the Visual Studio Marketplace, then add Grok from the Manage Providers panel; there is no separate VSIX per provider.

Can I use my Grok account in iolys?

Yes. Add Grok in Manage Providers, install the managed Grok Build CLI, and sign in with your Grok account in the browser. Access, allowance, and billing follow that account and its plan; iolys does not include Grok usage.

Is Grok the same as the Groq provider?

No. Grok Build is xAI’s coding agent, connected through its CLI and your Grok account. Groq is a separate API provider in iolys, and Grok models offered through API gateways such as OpenRouter use those gateways’ keys and billing.

Can I choose Grok’s reasoning effort level?

Yes, for models that advertise graded effort levels. Open the model options beside the prompt. grok-4.7 offers xhigh, high, medium, and low. Grok must confirm the selected model and effort before the prompt is sent.

Can Grok search the web and read documentation?

Yes. Grok’s native Web Search and Fetch URL tools are always available while Grok is selected. When a search result arrives without citations, iolys adds a warning that it could not be verified against retrieved pages.

Can Grok use Visual Studio build and test tools?

Yes. Grok uses the tools supplied by iolys to read and edit code, run builds, and run tests, under your permission mode. Grok’s own file, shell, and subagent tools are not enabled in this integration.

Can I see my Grok usage and costs?

Each turn shows the cost and tokens reported by Grok. Open Show usage from the chat toolbar for your plan and the remaining included allowance when Grok reports it. When Grok does not report an allowance, iolys shows it as unavailable rather than guessing.

How is the Grok CLI installed and updated?

Open Manage Providers and select Grok. iolys downloads the official Windows Grok Build CLI from xAI into its own managed folder, separately from any standalone installation, and can reinstall or uninstall it from the same panel.

Can I keep other providers configured?

Yes. Grok can sit alongside cloud APIs, local Ollama models, and other provider CLIs.
