# MCP & CLI testing

## Help agents run whole workflows with your tools.

Find the tool-call and context issues that stall agents mid-task, and fix them so your users’ agents can carry a workflow from start to finish.

[Start now for free](https://agents.withgauge.com)

[Read the guide](https://docs.withgauge.com/agents/guides/configure-a-scenario)

## Your tools, as agents meet them

Test authenticated MCP servers and APIs, CLIs, and native binaries in isolated sessions with the credentials each task needs.

## Every call on the record

See each tool call and command, its result, and where the agent went down the wrong path.

## Check every release

Run checks on pull requests with the Gauge GitHub App, or trigger hosted runs from your own CI.

## Can Gauge test authenticated MCP servers?

Yes. Hosted Gauge supports authenticated MCP servers and APIs, with the input versions and service credentials your task needs. The agent never sees your credentials directly.

## Can we test a release before it ships?

Yes. PR checks test candidate packages, executables, and skills using your existing build artifacts, then post results and session links on the pull request.

## Which coding agents and models can we test?

Gauge supports Claude Code, Codex, OpenCode, Pi, and Antigravity. The hosted Free plan includes open models on OpenCode and a first onboarding run on Claude Code and Codex at no cost. Upgrade to Pro or Enterprise for ongoing Claude Code and Codex runs and access to all supported agents.
