Tapp MCP server

Tapp

Tapp lets coding agents verify UI changes on real iOS, Android, and web surfaces, then turns reviewed proof into deterministic CI checks. It can inspect and drive screens, explore for technical failures, and save important journeys as replayable tests.

Exploration reports findings, coverage, evidence, and limits. Only the repository-connected gate returns pass, fail, or inconclusive. Tapp does not turn an autonomous crawl into a subjective "ship-ready" score.

Real evidence, not a mock: this public DemoApp run reached the requested iOS surface in three observed route actions. Watch 45 seconds of autonomous exploration or inspect a complete sanitized web evidence report.

Supported targets:

Windows hosts Android and web testing when their prerequisites are installed, and is the home of the Windows desktop target.

Give Tapp to your coding agent

After setup, the whole user prompt is:

Use Tapp to test this app.

The official skill teaches the agent to choose the smallest useful operation, handle repositories with multiple app targets, inspect visual evidence, and keep exploration observations separate from gate decisions.

Claude Code, Codex, Cursor, Copilot, and other Agent Skills clients (recommended):

npx -y skills add aarwitz/tapp --skill tapp

This installs the open Agent Skills workflow into the current project and lets the agent run the npm CLI directly. Inspecting, focused evidence, autonomous exploration, deterministic replay, and gating need no MCP server, plugin, account, API key, global Tapp install, or pasted prompt block. Add -g for a user-wide install, or --agent claude-code, --agent codex, and similar selectors to constrain the clients. Start or restart the agent from the application repository and use the short prompt above.

Claude Code — optional enhanced skill and MCP tools:

claude plugin marketplace add aarwitz/tapp
claude plugin install tapp@tapp
