Build and validate experimental WebMCP tools for an existing web page. Use when an agent needs to expose a site's real workflows as page tools, create webmcp.init.js, define deterministic checks, or compare WebMCP with accessibility-tree automation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Generate and validate page WebMCP tools Create a durable artifact that exposes a real page workflow through WebMCP and proves that the tool behaves like the existing UI. ## Output Save the work under: ```text artifacts/<domain>/<task>/ manifest.json webmcp.init.js eval.json eval-report.md ``` ## Workflow 1. Define the user goal, required initial page state, allowed actions, and consequential actions that need explicit confirmation. 2. Explore the page with agent-browser. Record the existing UI behavior, success signal, failure states, and recovery path. 3. Write `manifest.json` with the goal, required state, available tools, expected calls, expected UI changes, recovery cases, and excluded secrets. 4. Create `webmcp.init.js` and `eval.json`. Prefer declarative WebMCP for semantic HTML forms. Use imperative tools only when the workflow cannot be expressed declaratively. 5. Load the script before navigation: ```bash agent-browser --init-script ./webmcp.init.js open https://example.com agent-browser webmcp list agent-browser webmcp invoke <tool> --params @fixture.json ``` …

How to install
mdr add fcakyon/claude-codex-settings/webmcp-gen@sha256:5af2f258eef98e78The line at the top of this page pins the label git:20261001.f7836da, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
