Documentation

brewpage-mcp

MCP server for BrewPage -- publish and manage HTML, KV, JSON, and file content directly from AI assistants.

What is BrewPage

BrewPage is a free instant hosting platform designed for AI agents and developers. One POST request publishes HTML, Markdown, a multi-file site, a JSON document, or a binary file and returns a stable HTTPS short URL -- no accounts, no API keys, no infrastructure setup. Every resource carries an owner token returned at creation time: use it to update content in place (keeping the same URL), delete the resource, or authenticate list operations across sessions. brewpage-mcp exposes this API as fourteen typed MCP tools so any compatible agent -- Claude, Codex, Gemini, Cursor, Cline -- can publish, update, fetch, and manage BrewPage HTML, JSON, KV, and file content without leaving the conversation.

brewpage-mcp

Tools

Fourteen tools are available, grouped by resource: HTML, JSON, KV, Files, Sites, and Discovery. All write operations return an owner token; keep it to modify or delete the resource later. Any update (PUT) operation requires the original ownerToken -- it is the backend's authorization gate. password is optional on reads/creates; if set, it is sent as the X-Password header.

HTML

`publish_html`

Publish HTML or Markdown content to BrewPage. Returns a public URL and owner token.

Parameters: content (string), format (HTML | MARKDOWN, default HTML), namespace (optional -- omit to keep the page private/unlisted: reachable only by its link, not in the gallery, not indexed by search engines; pass public only when the user explicitly wants it gallery-listed and search-indexed), password (optional), ttlDays (1--30, default 15), filename (optional, used as title fallback), showTopBar (optional boolean -- adds a toolbar with filename, Download button, and theme toggle).

Example prompt that invokes this tool:

"Save this HTML report so I can share the link with my team."

publish_html(content="<h1>Report</h1>...", format="HTML", ttlDays=15)

`update_html`

Update an existing HTML or Markdown page in place, preserving its short URL. Requires the original ownerToken returned at creation.

Parameters: namespace (string), id (string), content (string, the new body), ownerToken (string), format (optional HTML | MARKDOWN | code, defaults to HTML).

Example prompt:

"Fix the typo in the report I published earlier -- same link."

update_html(namespace="public", id="aBcDeFgHiJ", content="<h1>Updated</h1>...", ownerToken="tok_...")

`get_page`

Fetch the content of a published BrewPage HTML page by namespace and ID.

Parameters: namespace (string), id (string), password (optional, if the page is password-protected).

Example prompt:

"Retrieve the content of my published page so I can continue editing it."

get_page(namespace="public", id="aBcDeFgHiJ")

Files

`publish_file`

Upload a file to BrewPage by fetching it from a URL. Returns a public URL and owner token. Supports images, PDFs, video, audio, code files, and archives.

Parameters: url (string, the source URL to fetch), namespace (optional -- omit to keep the file private/unlisted: reachable only by its link, not in the gallery, not search-indexed; pass public only to list and index it), filename (optional custom filename).

Example prompt:

"Upload this PNG and give me a shareable link."

publish_file(url="https://example.com/diagram.png")

Sites

`publish_site`

Publish a single-page or multi-file HTML site. Pass entryContent for a single page or files (array of {path, content}) for a multi-file site. Supports password protection, TTL, and owner token grouping.

Parameters: entryContent (string, mutually exclusive with files), files (array of {path, content}, mutually exclusive with entryContent), entry (optional entry file path, default index.html), namespace (optional -- omit to keep the site private/unlisted: reachable only by its link, not in the gallery, not search-indexed; pass public only to list and index it), password (optional), ttlDays (1--30, default 15), ownerToken (optional, groups site under an existing owner).

Example prompt:

"Deploy this static site with index.html and style.css."

publish_site(files=[{"path": "index.html", "content": "..."}, {"path": "style.css", "content": "..."}])

JSON

`publish_json`

Publish a JSON document to BrewPage. Returns a public URL and owner token. The body may be passed as a JSON string or as a structured object.

Parameters: json (string or object, the JSON payload), namespace (optional -- omit to keep the document private/unlisted: reachable only by its link, not in the gallery, not search-indexed; pass public only to list and index it), password (optional), ttlDays (optional, 1--30, default 15), tags (optional string[]).

Example prompt:

"Save this config blob as a JSON document I can fetch later."

publish_json(json={"mode": "dark", "version": 3}, ttlDays=15)

`get_json`

Fetch a published JSON document by namespace and ID.

Parameters: namespace (string), id (string), password (optional, sent as X-Password if set).

Example prompt:

"Read back the JSON document I just stored."

get_json(namespace="public", id="aBcDeFgHiJ")

`update_json`

Update an existing JSON document in place, preserving its short URL. Requires the original ownerToken.

Parameters: namespace (string), id (string), json (string or object, the new payload), ownerToken (string).

Example prompt:

"Bump the version field in that JSON doc to 4."

update_json(namespace="public", id="aBcDeFgHiJ", json={"mode": "dark", "version": 4}, ownerToken="tok_...")

KV

`publish_kv`

Create a new KV (key/value) entry. Returns a public URL and owner token. The KV entry is addressed by (namespace, id, key); this tool creates the entry and emits the generated id along with the owner token.

Parameters: key (string), value (string), namespace (optional -- omit to keep the KV store private/unlisted: reachable only by its link, not in the gallery, not search-indexed; pass public only to list and index it), password (optional), ttlDays (optional, 1--30, default 15), tags (optional string[]).

Example prompt:

"Store the API key under the label 'staging-token' so I can reuse it next session."

publish_kv(key="staging-token", value="abc123")

`set_kv`

Set or replace the value at an existing (namespace, id, key) slot. Requires the original ownerToken.

Parameters: namespace (string), id (string), key (string), value (string), ownerToken (string).

Example prompt:

"Update the staging-token value to the new secret."

set_kv(namespace="public", id="aBcDeFgHiJ", key="staging-token", value="def456", ownerToken="tok_...")

`get_kv`

Fetch the value stored at (namespace, id, key).

Parameters: namespace (string), id (string), key (string), password (optional, sent as X-Password if set).

Example prompt:

"What did I store under staging-token?"

get_kv(namespace="public", id="aBcDeFgHiJ", key="staging-token")

Discovery

`search_gallery`

Browse the public gallery of BrewPage pages, or list resources you own. Returns a paged result with metadata (id, title, view count, created date). All parameters are optional; with no parameters this returns the most recent public pages.

Parameters: q (optional search query), page (optional, 0-indexed), size (optional page size), sort (optional date | views), mine (optional boolean -- list only resources owned by ownerToken), ownerToken (required only when mine=true).

Example prompt:

"What did I publish last week?"

search_gallery(mine=true, ownerToken="tok_...", sort="date")

Management

`delete_resource`

Delete a BrewPage resource (HTML page, KV store, JSON collection, or file) using the owner token received at creation.

Parameters: type (html | kv | json | file), namespace (string), id (string), ownerToken (string).

Example prompt:

"Delete the page I just published -- namespace public, id aBcDeFgHiJ."

delete_resource(type="html", namespace="public", id="aBcDeFgHiJ", ownerToken="tok_...")

`get_stats`

Parameters: tz (optional IANA timezone string, e.g. Europe/Lisbon, defaults to UTC).

Example prompt:

"How many pages are currently hosted on BrewPage?"

get_stats()

Common LLM Query to BrewPage Tool Mapping

LLM query / intent	Tool	Notes
"Publish this HTML so I can share it"	`publish_html`	`format=HTML`; save `ownerToken`
"Share these meeting notes as a link"	`publish_html`	`format=MARKDOWN`; readable rendered output
"Host this AI-generated artifact"	`publish_html`	`namespace` optional; private/unlisted by default -- pass `public` to gallery-list + index
"Upload this image / PDF / video"	`publish_file`	Fetches from URL; inline preview on short URL
"Deploy this static site"	`publish_site`	Pass `files` array or `entryContent`
"Fix a typo in the page I shared -- same link"	`update_html`	Requires `ownerToken`; URL stays the same
"Remove the page I published"	`delete_resource`	Requires `ownerToken` from creation
"Read back the page I published"	`get_page`	Returns raw content for editing
"How many pages are on BrewPage?"	`get_stats`	Returns platform totals
"Store JSON state between turns"	`publish_json`	Returns short URL + owner token
"Read that JSON document back"	`get_json`	By `namespace` + `id`
"Update the JSON I stored"	`update_json`	Requires `ownerToken`; preserves URL
"Save a value under a label / key"	`publish_kv`	Create a new KV slot
"Change the KV value I stored"	`set_kv`	Requires `ownerToken`
"What did I store under that key?"	`get_kv`	By `namespace` + `id` + `key`
"List my published pages" / "What did I publish?"	`search_gallery`	Set `mine=true` + `ownerToken`
"Browse the public BrewPage gallery"	`search_gallery`	Optional `q`, `sort=date\|views`

Owner Token

Every publish response includes an owner token -- the only credential that allows updating or deleting your content. Save it. It cannot be recovered.

Reuse it via X-Owner-Token on subsequent creates to group resources under one owner.
Pass it to delete_resource to remove content.
Pass it to get_page (not needed for reads, but required for listing your own resources via the REST API).

Changelog

1.6.0 -- 2026-06-05

Private-by-default publishing. When namespace is omitted, all five publish tools (publish_html, publish_file, publish_site, publish_json, publish_kv) now send an explicit unlisted namespace (priv-<random>) instead of letting the backend default to public. Omitted namespace = unlisted (reachable only by its link, not gallery-listed, not search-indexed); pass namespace: "public" explicitly to list + index. Non-breaking: namespace stays optional.
Publish responses for non-public namespaces now append an "Unlisted link" notice explaining how to make content public.
Tool descriptions and README rewritten to reflect the private-by-default model.

1.5.0 -- 2026-05-21

Add 8 new MCP tools: update_html, publish_json, get_json, update_json, publish_kv, set_kv, get_kv, search_gallery.
Tool count: 6 -> 14. Full coverage of HTML update, JSON CRUD, KV CRUD, and gallery discovery (incl. owner-scoped listing via mine=true).
Update operations (update_html, update_json, set_kv) require the original ownerToken; password (when set) is forwarded as X-Password.

1.4.0 -- 2026-05-12

Sync to spec 1.31.0 -- adds raw text/* and application/octet-stream variants on POST /api/html; PUT mirror; 422 with supportedTypes.
