The WireMock Cloud agent skills plugin gives coding agents specialised knowledge and workflows for building and managing mock APIs in WireMock Cloud. Once installed, your agent can generate complete API simulations, create and validate stubs, convert stubs to stateful or data-driven variants, author response templates, review a simulation for completeness, and search the WireMock Cloud documentation - all without leaving your editor or terminal.
Agent Skills is an open format for extending AI agents with domain-specific capabilities. A skill is a folder containing a
SKILL.md file with instructions and optional supporting resources. Agents discover skills at startup, load them when relevant, and follow the instructions to complete tasks.
Available skills
The plugin bundles eight skills:/build-api-simulation is a user-invocable slash command - type it to kick off a full API simulation workflow. The remaining skills are triggered automatically by context when relevant to the task at hand.
Supported agents
The Agent Skills format is supported by a growing number of coding agents, including Claude Code, Cursor, Codex CLI, GitHub Copilot, VS Code, and more.Two ways to connect
The skills need a WireMock Cloud MCP server to actually act on your behalf - it’s what lets a skill call the WireMock Cloud API to create mock APIs, manage stubs, and so on. WireMock Cloud ships the plugin in two variants that differ only in which server they talk to:
Install whichever matches your setup - not both, since they’d both register an MCP server named
wiremock.
- Installing the agent skills plugin - the remote variant, recommended for most users.
- Installing the local agent skills plugin - the local variant, for offline setups or when you need locally stored HTTP request credentials.
Skills vs MCP
The WireMock Cloud agent skills and the WireMock MCP server are complementary:- MCP gives your agent tools - the ability to call the WireMock Cloud API, search stubs, manage mock APIs, and make HTTP requests.
- Skills give your agent expertise - knowledge of WireMock Cloud concepts, best practices, and multi-step workflows that orchestrate those tools effectively.
