For AI agents — MCPBundles Directory API
Recommended: Directory API v1 over HTTP for detail and anonymous invoke when eligible (not MCP JSON-RPC on the publisher URL; no user MCPBundles credentials on v1).
GET https://www.mcpbundles.com/api/directory/v1/servers/cellpy-mcp-119b0a8172
GET https://www.mcpbundles.com/api/directory/v1/servers/cellpy-mcp-119b0a8172?live=1 (optional live refresh)
GET https://www.mcpbundles.com/api/directory/v1/servers/cellpy-mcp-119b0a8172/tools/<tool> (one tool: schema + invoke.url)
POST https://www.mcpbundles.com/api/directory/v1/servers/cellpy-mcp-119b0a8172/tools/{tool}
POST body: flat JSON of tool argument names and values; not an arguments wrapper. Replace {tool} with a tool name from GET detail.
Restricted agent shell (ChatGPT Codex desktop, some IDE sandboxes):
Default command sandboxes often block outbound network. curl exit 6 or "Could not resolve host" for www.mcpbundles.com is usually sandbox DNS — not evidence this site is down.
Retry the same Directory API GET with sandbox_permissions "require_escalated" and a one-sentence justification on the shell tool (Codex on-request approval). Do not tell the user the site is unreachable from sandbox curl alone.
Example justification: Run the public MCPBundles Directory API search outside the command sandbox to complete the user's MCP server lookup.
If the agent has browser access (e.g. Codex @Browser): open https://www.mcpbundles.com/?q=<query> or stay on this page — no shell network needed. Use WebMCP search_mcp_servers then get_mcp_server (document.modelContext / page tools; refresh with fetchTools or getTools if a tool id is missing from the snapshot). Read-only directory search; same index as Directory API v1 GETs. Neither WebMCP nor Directory API v1 uses user MCPBundles credentials.
Without a browser: after escalated curl fails, use GET https://www.mcpbundles.com/?q=<query> with Accept: text/markdown for ranked results.
Hub MCP (connected session): discover_mcp_servers — same filter semantics as search_mcp_servers.

Retrieve the complete block validation ruleset for this Cellpy account.
Call this tool BEFORE generating any block HTML or CSS.
The rules returned depend on the account's trust level — do not guess at them.

Get Image Upload Url — Mint a short-lived direct-upload URL for ONE image file, for use with
push_to_workspace/push_form_to_workspace's images array. Use this
INSTEAD OF base64-encoding an image into a tool call's data field
whenever you have real file/network access yourself (e.g. can run
curl or an equivalent HTTP request outside this conversation) —
inlining image bytes as base64 burns significant context/tokens for
no benefit once this exists, and is capped at 4 MB besides. If
there's more than one image, or you'r
Get Video Upload Url — Mint a short-lived direct-upload URL for ONE video file (mp4 or webm,
50 MB max), for use with push_to_workspace/push_form_to_workspace's
videos array. There is no base64/data option for video — the file is
always too large for that to be practical. Use this whenever you
have real file/network access yourself (e.g. can run curl or an
equivalent HTTP request outside this conversation). If there's more
than one video, or you're not sure you have that kind of access
(mobile app, Claude Desktop with
Get Media Upload Page Url — Mint a link to a browser page where the user can upload as many
images and videos as they want (up to 20 files total) directly from
their own device — no base64, no tool-call involvement at all.
Prefer this over get_image_upload_url/get_video_upload_url whenever
more than one file is involved, or whenever you can't tell if the
user has real file/network access (e.g. they're on the Claude
mobile app or Claude Desktop, neither of which can run a raw PUT
themselves) — those environments have no way
List Pending Uploads — Check what's been uploaded so far through a link from
get_media_upload_page_url. Call this after the user says they're
done uploading (or if you want to check progress). Returns each
file's key and filename, and whether it's an image or video — pass
the key straight into push_to_workspace/push_form_to_workspace's
images or videos array as { name, key, mimeType } (images can
alternatively use { data }). The user already confirmed rights via
a checkbox on the upload page itself, so you can set

Operate Cellpy?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal

Load Block — Load an existing published block version into the designer's Workspace.
Use this before modifying a block: load the version, read its html and css
with get_block, make the required changes, then push back with the
appropriate tool:
- If get_block reports Type: form → use push_form_to_workspace
- Otherwise → use push_to_workspace
Call list_blocks first to confirm the slug exists and see available versions.
Get Block — Retrieve the HTML and CSS source of a published block version.
Use this to read a block's current content before modifying it.
CLAUDE DESIGN WORKFLOW:
After retrieving the block content, check the 'Type' field in the response:
If Type is 'form':
This is a FORM BLOCK. After modifying html/css, push changes back with
push_form_to_workspace (NOT push_to_workspace) so the form field metadata
is preserved. Pass the fields array shown in the response (edit as needed).
If Type is not shown (we
Photo Search — Search for freely licensed stock photos from Pexels and Pixabay.
Call this tool when the block design requires a photo, background image, or illustration.
After selecting a result, pass its url in the images array of push_to_workspace
using the intended filename as name (e.g. name: "hero-bg.jpg").
No attribution markup is required for Pexels or Pixabay images in generated blocks.
Photos from Pexels and Pixabay are trusted sources — no rights confirmation needed.
PREREQUISITE: The user must ha
Save Api Keys — Save the user's Pexels and/or Pixabay API keys to their Cellpy account.
Call this after the user pastes their key(s) in response to a photo_search failure.
Only pass the keys the user actually provided — omit the other to leave it unchanged.
After saving, immediately retry the photo_search that originally failed.
Push To Workspace — Push a new or updated block into the designer's Workspace for review.
The block is NOT published to the CDN — the designer must open the Workspace
on cellpy.com and click 'Publish to Staging' before it goes live.
Call list_block_rules first to get the complete validation ruleset for this account.
Rules Claude must follow before calling this tool:
- HTML must be a single root <section> or <article> element. No <html>, <head>, or <body>.
- No <script>, <iframe>, <object>, <embed>, or <form> tags
Push Form To Workspace — Push a form block to the Designer's Cellpy Workspace for review and publishing.
Use this tool for lead capture forms. For web blocks (hero sections, pricing
tables, etc.), use push_to_workspace instead.
Full flow after calling this tool:
1. The form block lands in the Designer's Workspace at cellpy.com/workspace
2. The Designer reviews and edits it in the Workspace — they can adjust
field labels, types, order, and the success message using the visual
Fields editor without touching code
3.
List Blocks — List all blocks in your Cellpy account with their CDN URLs and versions.
Push Instant Update — Push a change directly to an ALREADY-LIVE container — no Workspace review,
no approval step. The change is visible on the real website within seconds.
Only use this when the user explicitly asks for an urgent/immediate change
(e.g. 'fix this typo on the live site right now', 'swap the banner for our
flash sale immediately'). For normal block authoring, use push_to_workspace
instead — it lets a human review before anything goes live.
This tool only works if the account owner has enabled 'Instan
Check Instant Update Readiness — Check whether a container is ready for push_instant_update WITHOUT pushing
any content — safe to call as often as needed. Use this before an instant
update if you want confidence first, especially for accounts on external
storage where credentials can go stale between checks. This tool never
writes block content; it only reports status.
