The skill sets up a visual feedback toolbar and an associated MCP server for Next.js projects. It involves downloading and executing packages from the npm registry and introduces an indirect prompt injection surface by feeding browser-based annotations directly into the agent's context.

What does this agent skill do?
Agentation Setup
Set up the toolbar and, when requested, connect it to the user's coding agent. A visible toolbar and a healthy MCP server do not prove that browser feedback reaches the agent. Verify that final step before calling setup complete.
Steps
-
Inspect the project
- Read the project's instructions and detect its package manager.
- Look for
agentationand an existing<Agentation>mount before installing. - If already mounted, inspect its
endpointand current MCP setup. Do not exit just because the component exists, and do not add a duplicate mount. - Install
agentationif missing, using the existing lockfile's package manager.
-
Choose the connection mode from the request
- For MCP or live agent feedback, use the same HTTP server URL as the agent.
The default local server is
http://localhost:4747; preserve an existing custom port or proxy URL. Never assume the browser and agent use the same machine when the project is remote. - For manual copy/paste only, omit
endpointand explain that feedback remains in this browser. Do not silently enable a server connection. - If the intended mode is unclear, ask one brief question while inspecting the existing project. Keep working on independent setup checks.
- For MCP or live agent feedback, use the same HTTP server URL as the agent.
The default local server is
-
Add or update the component
For a Next.js App Router project, render in the root layout's body after children. For Pages Router, render after
Componentinpages/_app. Preserve any existing callbacks and options.import { Agentation } from "agentation"; // Use the actual server URL selected above for MCP sync: {process.env.NODE_ENV === "development" && ( <Agentation endpoint="http://localhost:4747" /> )}The package provides its own client boundary. Keep the application's root layout server-rendered unless the project has another reason to change it.
-
Configure the agent when MCP was requested
- Use the project's existing MCP client and configuration conventions.
- The launch command must include the
serversubcommand:npx -y agentation-mcp server. - For supported agents,
npx add-mcp "npx -y agentation-mcp server"is one setup option. For Claude Code, useclaude mcp add agentation -- npx -y agentation-mcp serveror the init wizard. - Apply the same custom port to the server command and component endpoint.
- Restart or reconnect the agent when its configuration requires it. Do not create a second HTTP server on a port already owned by the working server.
-
Verify the complete connection
- Run
npx agentation-mcp doctorfor service diagnostics. For a custom URL, usedoctor --http-url <url>when supported by the installed version. - Open the app and create one clearly identified test annotation through the
toolbar. Read it with
agentation_get_all_pendingor session-scoped tools. - Check the exact test comment and page, not just a nonzero count or health response. Leave unrelated annotations alone.
- If annotations are empty, check the component endpoint, browser network failures/CORS, and whether the agent and browser point to the same server.
- If browser or MCP tools are unavailable, say exactly which part remains unverified and give the user this final check. Do not claim live sync works.
- Run
Notes
- The development guard prevents the toolbar from appearing in production.
- Agentation requires React 18 or newer.
- Installing the toolbar does not install, configure or connect an MCP server.
- Manual copy mode is supported and does not need a running server.
