siteglass-mcp
Enables archival of any public URL as interactive snapshot (rrweb, PDF, PNG) and autonomous web QA for apps (register, scan, generate and run end-to-end flows).
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
siteglass_register_siteRegister a web app (its deployed URL) with siteglass and get an ownership-proof token to place on it. Step 1.
siteglass_verify_siteCheck that the ownership-proof token is live on the site. Step 2 (after placing the token).
siteglass_scanCrawl a verified site (first scan per site is free). Returns a crawl_id; if still running, poll with siteglass_get_scan. Step 3.
siteglass_get_scanRead a scan's report + findings by crawl_id (use after siteglass_scan if it was still running).
siteglass_generate_flowsDerive executable E2E test flows from a scan (LLM). Step 4. Returns flow ids.
siteglass_run_flowRun one test flow. Returns a run_id; if still running, poll with siteglass_get_run. Step 5.
siteglass_get_runRead a flow run's per-step results + capture URLs by run_id (use after siteglass_run_flow if still running).
siteglass_renderArchive ANY public web page for a few sats — a permanent, shareable snapshot, returned as a permalink. The bot-friendly alternative to archive.today: no CAPTCHA, no signup, no ownership verification, callable programmatically. Default 'rrweb' captures the live rendered DOM (navigable, post-JS, selec…
siteglass_get_renderFetch an archive once its Lightning invoice is paid. Returns the permalink when ready, or a pending status.
siteglass_set_credentialsProvide a test account (username/password) so authenticated flows can log in to the site.
siteglass_feedbackSend feedback to the siteglass team (bugs, missing features, anything). Works for agents and people alike.
siteglass_scan_localScan a web app you're building — FREE: no account, no ownership verification, no payment. Runs a headless browser on YOUR machine to crawl the URL (works on http://localhost:PORT or any URL your machine can reach — nothing is tunneled to siteglass), then siteglass analyzes the crawl server-side and …

Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
12/12 tools missing one or more hints — siteglass_register_site (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); siteglass_verify_site (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); siteglass_scan (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +9 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Descriptions match behaviour
4 tools describe read intent but their handlers mutate — siteglass_register_site (line 41: fs.mkdirSync(path.dirname(KEY_FILE), { recursive: true })); siteglass_verify_site (line 41: fs.mkdirSync(path.dirname(KEY_FILE), { recursive: true })); siteglass_get_scan (line 41: fs.mkdirSync(path.dirname(KEY_FILE), { recursive: true }))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tests exist
No test files found
Add tests that exercise each declared tool.
Secrets not written to files
1 secret value written to files
Avoid persisting secrets to disk. Keep them in memory or your secret manager.
Tool description accuracy
4 tools have description/behavior mismatches: siteglass_register_site: description implies read-only but handler writes/deletes/executes; siteglass_verify_site: description implies read-only but handler writes/deletes/executes; siteglass_get_scan: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
