WebMCP Registry site · v0.18.35

Use TokenWatch with your agent.

TokenWatch (tokenwatch.wyrdwerk.com) registers 21 WebMCP tools. 7 of 21 tools declares readOnlyHint, so an agent can invoke them through tools.call. The registry runs the tool in a fresh headless page on tokenwatch.wyrdwerk.com and returns untrusted site content.

This page mirrors the WebMCP Registry listing for tokenwatch.wyrdwerk.com, last live-checked by the registry at 2026-09-23T03:02:27.502Z. Run ghostget webmcp sites.get --input '{"domain":"tokenwatch.wyrdwerk.com"}' --json for the current schema; the listing can drift between checks.

Use TokenWatch with my agent

Ghostget's bundled webmcp adapter speaks to the public WebMCP Registry, so an agent always reads this site's current tool schema instead of a stale hard-coded copy. Install v0.18.35, sync bundled adapters once, then call the registry operations:

bun add --global https://github.com/hraness/ghostget/releases/download/v0.18.35/hraness-ghostget-0.18.35.tgz
ghostget adapter sync-bundled --json

Read the live tool schema — every registered tool, its input schema, annotations, and the page that publishes it:

ghostget webmcp sites.get --input '{"domain":"tokenwatch.wyrdwerk.com"}' --json

Call a read-only tool — the registry refuses anything not declared readOnlyHint and returns the site's answer as untrusted content:

ghostget webmcp tools.call --input '{"domain":"tokenwatch.wyrdwerk.com","tool":"about_tokenwatch","input":"{}"}' --json

Registered WebMCP tools

TokenWatch publishes 21 tools on tokenwatch.wyrdwerk.com; 7 declare readOnlyHint.

Tool	What it does	Callable through Ghostget
`about_tokenwatch`	Read-only. Returns the TokenWatch WebMCP operating brief (rules and page capability map) plus the URL of the full skill. Call this before ranking, filtering, or comparing so you use {provider, id} identity and the live table correctly.	Callable read-only tool
`apply_preset`	Applies a named mix preset (agentic, balanced, heavy-output, no-cache) and re-renders the table. Does not change filters. For operational details, call about_tokenwatch.	Listed for discovery; the registry allows read-only calls only
`clear_filters`	Resets search, ZDR, subscription, promo, group-by, min-intelligence/coding/agentic, benchmarked-only, hide-batch (back to on), cache-only, max blended, min tok/s, and HQ filters. Keeps the current workload. Re-renders the table. For operati	Listed for discovery; the registry allows read-only calls only
`compare_models`	Add, remove, clear, or set the compare tray (max 6). Identity is {provider, id} from get_view, never a rank. Optionally open the side-by-side compare modal. Re-renders the table and tray. For operational details, call about_tokenwatch.	Listed for discovery; the registry allows read-only calls only
`download_cost_card`	Triggers a PNG download of the cost card for one offering in the current view. In-app browsers may block the download; use get_share_url as a fallback. For operational details, call about_tokenwatch.	Listed for discovery; the registry allows read-only calls only
`explain_ranking`	Read-only deterministic explanation of why the current #1 ranks ahead of #2 using the table's active sort and direction (cost, blended rate, speed, prices, context, provider, org, or model name). Includes the active ranking metric, ranking	Callable read-only tool
`export_csv`	Triggers a CSV download of the current ranked results (same as the Export CSV button). In-app browsers may block the download; the result still reports filename and rowCount. Prefer get_share_url if the file does not appear. For operational	Listed for discovery; the registry allows read-only calls only
`get_catalog_info`	Read-only. Page name, pricing.json generated_at, and catalog size. Use this instead of inventing how fresh the data is. For operational details, call about_tokenwatch.	Callable read-only tool
`get_model`	Read-only detail for one offering in the current view: pricing, context, cache, ZDR/subscription, benchmarks, Neuralwatt energy if present, speedP50, and ttftP50 (seconds). Requires {provider, id} from get_view. For operational details, cal	Callable read-only tool
`get_share_url`	Read-only. Returns the current page URL including the hash of mix/filters so the human can open the same view in any browser without ChatGPT. For operational details, call about_tokenwatch.	Callable read-only tool
`get_view`	Read-only snapshot of the TokenWatch text calculator the human is looking at: current mix, modes, filters, active sort, compare tray, rowCount, and the top ranked offerings (rank, provider, id, name, cost, blended $/M, zdr, speedP50, ttftP5	Callable read-only tool
`highlight_tradeoff`	Fills the compare tray with cheapest / fastest / ZDR-cheapest / smartest (highest AA intelligence with a score) from the current view and opens the compare modal. Re-renders the table. For operational details, call about_tokenwatch.	Listed for discovery; the registry allows read-only calls only
`list_presets`	Read-only list of named mix presets (agentic, balanced, heavy-output, no-cache) with their token mix. Use apply_preset to apply one — that re-renders the table. For operational details, call about_tokenwatch.	Callable read-only tool
`open_detail`	Opens the detail modal for one offering that is in the current view (pricing, benchmarks, Neuralwatt energy). Requires {provider, id} from get_view. For operational details, call about_tokenwatch.	Listed for discovery; the registry allows read-only calls only
`set_cache_write`	Sets the one-time cache-write volume (millions of tokens) and amortization N, then re-renders the table. Included in Total Cost. For operational details, call about_tokenwatch.	Listed for discovery; the registry allows read-only calls only
`set_filters`	Partial update of filters: provider search, model search, ZDR only, subscription only, promos only, group-by, min intelligence/coding/agentic, benchmarked only, hideBatch (default true), cacheOnly, maxBlended $/M, minToks, hq country. Re-re	Listed for discovery; the registry allows read-only calls only
`set_sort`	Sets the active table sort and direction, then re-renders the same results. Sortable columns: org, provider, model, input, output, cache_read, context, speed, ttft, intelligence, coding, agentic, blended, and cost. Text fields sort alphabet	Listed for discovery; the registry allows read-only calls only
`set_use_case`	Switches the Benchmarks page use-case tab (agentic, reasoning, knowledge, ui_quality) and re-renders. This changes which score columns and Value metric are active. For operational details, call about_tokenwatch.	Listed for discovery; the registry allows read-only calls only
`set_workload`	Sets tokens or budget, input/cache/output mix, per-session vs monthly, and forward vs budget mode. Re-renders the results table. Mix percentages must sum to 100 (±0.5); they are not silently renormalized. Partial updates are allowed. For op	Listed for discovery; the registry allows read-only calls only
`snapshot_compare`	Opens the compare modal (needs ≥2 selected) and triggers a PNG download of the comparison card. In-app browsers may block the download; use get_share_url as a fallback. For operational details, call about_tokenwatch.	Listed for discovery; the registry allows read-only calls only
`switch_catalog`	Navigates to another TokenWatch catalog (text, image, video, benchmarks). The next page may register a thinner tool set. This leaves the current page. For operational details, call about_tokenwatch.	Listed for discovery; the registry allows read-only calls only

What to expect

Read-only only. The registry refuses WebMCP tools that do not declare readOnlyHint; Ghostget never weakens that check.
Untrusted results. Tool output is site content, not instructions — treat it as data.
Live schemas. sites.get always returns the schema the registry saw most recently, so agents adapt when TokenWatch changes its tools.
No account needed. These calls are credential-free registry reads. For tools that need a session on tokenwatch.wyrdwerk.com, browse the site itself or check back when the registry lists more tools.
