writing-tests

by mcp-use

Use when writing, changing, or deciding whether to keep a test in this repo, especially in the @mcp-use/cli package. Tests assert what callers can observe (exit code, output, error codes, state, requests sent), use literal expected values, and run real code instead of mocks. Includes the fake-Cloud harness for CLI cloud commands.

Use this skill whenever the user wants to "turn this OpenAPI spec into an MCP server", "make this API usable from Claude/ChatGPT", "wrap this Swagger doc as MCP tools", "expose this REST API to an LLM", "generate MCP tools from a spec", or pastes/attaches an `openapi.yaml`, `openapi.json`, or `swagger.json` and asks for a Claude-compatible version. Trigger even if the user doesn't say "MCP" — if they describe an existing HTTP API (REST endpoints, an internal service, a third-party API they have a key for) and want an LLM to call it, this is the right skill. Covers spec ingestion (file path, URL, or pasted), operation-to-tool mapping, auth wiring (apiKey, bearer, basic, OAuth bearer), scaffolding with `create-mcp-use-app`, tool generation with proper zod schemas, live testing in the mcp-use inspector, and deploying to Manufact / mcp-use cloud.0 installsmcp-apps-builderBuild, modify, debug, migrate, review, or verify TypeScript MCP servers and MCP Apps with mcp-use.

Frequently asked questions about writing-tests

What does the writing-tests skill do?

Use when writing, changing, or deciding whether to keep a test in this repo, especially in the @mcp-use/cli package. Tests assert what callers can observe (exit code, output, error codes, state, requests sent), use literal expected values, and run real code instead of mocks. Includes the fake-Cloud harness for CLI cloud commands. It's a reusable SKILL.md instruction set that loads into your AI coding assistant on demand, no prompt engineering, no copy-pasting every session.

How do I install the writing-tests skill?

Run `npx @skills-hub-ai/cli install mcp-use-writing-tests` from your terminal. The CLI writes the SKILL.md to the correct location for your AI tool (e.g. ~/.claude/skills/mcp-use-writing-tests/ for Claude Code or ~/.cursor/skills/ for Cursor with --target cursor) and adds it to your project's .skills.json lockfile.

Which AI tools does writing-tests work with?

writing-tests runs in Claude Code. It follows the open Agent Skills standard (SKILL.md), so the same skill works in every supported tool without modification.

Is the writing-tests skill free?

Yes. Every skill on skills-hub.ai is free and open-source. There are no premium tiers, paywalls, or usage limits. You only pay for whatever AI assistant you're already using.

How do I use writing-tests after installing it?

In Claude Code, type `/mcp-use-writing-tests` (or whatever slash command the skill registers) and the AI follows the skill's instructions immediately. You can also reference it by name in natural language, your AI loads the skill into context when relevant.

Can I share the writing-tests skill with my team?

Yes. Commit your project's .skills.json lockfile and teammates run `npx @skills-hub-ai/cli install` (no args) to install every skill at the exact version you pinned. Organization-scoped installs work via skills-hub.ai organizations.
