Claude Code: deny. ### `delete_resource` - The name "delete_resource" says "delete": a word for removing or ending something. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Delete a BrewPage resource (HTML page, site, KV store, JSON document, or file) using the owner token. ``` ### `republish_site` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Republish (full-replace) an existing multi-file BrewPage site in place at the SAME URL/ID. Requires owner token. The uploaded bundle becomes the complete new file set — files absent from it are removed, new files added, matching files overwritten. Single-page: pass `entryContent`. Multi-page: pass `files` (array of `{path, content}`). Optional `entry` overrides the default `index.html`. Republishing preserves existing expiry. Old publications (made before 5 October 2026) are read-only: 409 OLD_PUBLICATION_READ_ONLY. Limits (call get_limits for current values): a request is at most 25 MB; a site at most 200 files, 5 MB per file and 20 MB in total; each path at most 380 characters. System files (.DS_Store, __MACOSX/ and similar) are skipped and never count; files with an unsupported extension or a too-long path are skipped and listed in notices. Entry: `entry`, else root index.html, else the shallowest HTML file. Errors: 400 = a site limit exceeded (the message names it and what to do), invalid path or no HTML file; 413 = request over 25 MB, too many files and form fields, or a file name/path too long; 422 = no servable file left. ``` ### `set_kv` - The name "set_kv" says "set": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Set or update a key in an existing BrewPage KV store. Requires owner token. The key name `hosting` is reserved. Old publications (made before 5 October 2026) are read-only: 409 OLD_PUBLICATION_READ_ONLY. ``` ### `update_html` - The name "update_html" says "update": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Update an existing BrewPage HTML/Markdown page. Requires owner token. Returns the updated page metadata. The link and delivery mode never change on update; an advisory deliveryModeReason and delivery notice are included when the new content uses browser features that may not work fully on a BrewPage link. Old publications (made before 5 October 2026) are read-only: 409 OLD_PUBLICATION_READ_ONLY. ``` ### `update_json` - The name "update_json" says "update": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Update an existing BrewPage JSON document. Requires owner token. Accepts a JSON object, array, or a JSON-encoded string. Old publications (made before 5 October 2026) are read-only: 409 OLD_PUBLICATION_READ_ONLY. ``` ## Can't be undone (5) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `publish_file` - The name "publish_file" says "publish": a word for a change that another call does not undo. - Tag outbound: The name "publish_file" says "publish": it sends or publishes something to other people. The input takes a URL (input.url): a request to a URL can carry data to whoever runs it. Description, as the server wrote it: ```untrusted-server-text Upload a file to BrewPage via URL. Repository defaults: 5 MiB for files/audio, 20 MiB for video. Returns its primary share link and owner token. Does not expose password or TTL inputs. Returns manageUrl (private): give it to the user privately; never publish it. Secrets allowed; likely ones are flagged in notices. For a secret: private namespace + password. ``` ### `publish_html` - The name "publish_html" says "publish": a word for a change that another call does not undo. - Tag outbound: The name "publish_html" says "publish": it sends or publishes something to other people. Description, as the server wrote it: ```untrusted-server-text Publish HTML or Markdown content to BrewPage (repository default limit 5 MiB). Returns its primary share link and owner token. Supports password protection, custom TTL, optional filename, and an opt-in top toolbar (showTopBar). When deliveryMode is omitted for a `public` page, the server may publish it on its own subdomain if the page needs browser features a BrewPage link does not provide; the result then includes deliveryModeReason and a delivery notice. Markdown raw HTML is allowlisted: scripts, styles, event handlers, forms and embeds are removed. Always share the returned URL. Returns manageUrl (private): give it to the user privately; never publish it. Secrets allowed; likely ones are flagged in notices. For a secret: private namespace + password. ``` ### `publish_json` - The name "publish_json" says "publish": a word for a change that another call does not undo. - Tag outbound: The name "publish_json" says "publish": it sends or publishes something to other people.

Repository defaults: 1 MiB per value, 1,000 keys per store; the key name `hosting` is reserved. Returns its primary share link and owner token. Returns manageUrl (private): give it to the user privately; never publish it. Secrets allowed; likely ones are flagged in notices. For a secret: private namespace + password. ``` ### `publish_site` - The name "publish_site" says "publish": a word for a change that another call does not undo. - Tag outbound: The name "publish_site" says "publish": it sends or publishes something to other people. Description, as the server wrote it: ```untrusted-server-text Publish an HTML site to BrewPage. Single-page: pass `entryContent`. Multi-page: pass `files` (array of `{path, content}`). Optional `entry` overrides default `index.html`. Use its returned primary link and retain the owner token. Limits (call get_limits for current values): a request is at most 25 MB; a site at most 200 files, 5 MB per file and 20 MB in total; each path at most 380 characters. System files (.DS_Store, __MACOSX/ and similar) are skipped and never count; files with an unsupported extension or a too-long path are skipped and listed in notices. Entry: `entry`, else root index.html, else the shallowest HTML file. Errors: 400 = a site limit exceeded (the message names it and what to do), invalid path or no HTML file; 413 = request over 25 MB, too many files and form fields, or a file name/path too long; 422 = no servable file left. Returns manageUrl (private): give it to the user privately; never publish it. Secrets allowed; likely ones are flagged in notices. For a secret: private namespace + password. ``` ## Changes things (4) Creates or changes something that can be changed back. Claude Code: ask. ### `bind_token` - The description's first verb is "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text Add an owner token to your BrewPage profile (as publish). Needs an admin token of that profile. ``` ### `mint_token` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Mint a new profile token with an admin token; the new token is shown once. Scope publish (default) or admin; expiry 30d, 90d, 1y or never. ``` ### `set_visibility` - The name "set_visibility" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text Hide or show a public publication in the gallery and sitemap. Link unchanged. ``` ### `update_hosting` - The name "update_hosting" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text Change delivery mode for a NEW publication (not a site, not a non-public HTML-format page). Requires owner token; pass the current hostingVersion when known. Mismatches are reported, not rejected: a stale version still applies, and OLD links or forced subdomain modes stay unchanged; the result then carries a delivery notice. Content updates never change hosting. ``` ## Only reads (6) Looks things up and changes nothing. Claude Code: allow. ### `get_json` - The name "get_json" says "get": a word for reading. - Tag private-data: The description's first sentence says "fetch" and "document": it reads documents. Description, as the server wrote it: ```untrusted-server-text Fetch a published BrewPage JSON document by namespace and ID. ``` ### `get_kv` - The name "get_kv" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch a value from a BrewPage KV store by namespace, ID, and key. ``` ### `get_limits` - The name "get_limits" says "get": a word for reading. - Tag private-data: The description's first sentence says "get" and "file": it reads files. Description, as the server wrote it: ```untrusted-server-text Get the current BrewPage upload limits (GET /api/limits): request size, site file count, per-file and total size, ZIP expansion, path and name lengths, TTL default/maximum, allowed file extensions and skipped system files. Sizes are bytes. With BREWPAGE_OWNER_TOKEN set: also reach (token|profile) and ownerMaxTtlDays. Call it before publishing a large or multi-file site. ``` ### `get_page` - The name "get_page" says "get": a word for reading. - Tag untrusted-input: The description's first sentence says "fetch" and "html": it reads web pages, which anyone can write. Description, as the server wrote it: ```untrusted-server-text Fetch stored rendered HTML or format-specific code/text by namespace and ID. This reads API content, not the owner-only original-source endpoint or browser viewer. Protected reads use the password header. ``` ### `get_stats` - The name "get_stats" says "get": a word for reading. - Tag private-data: The description's first sentence says "get" and "file": it reads files. Description, as the server wrote it: ```untrusted-server-text Get BrewPage platform-wide usage statistics including page count, file count, and storage usage.
