Install

How do I install the Just Publish MCP server?

Just Publish is a hosted endpoint at https://mcp.justpublish.ai/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 3 exposed · ~710 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
deploy ~277

Put a website live at a public URL. Use this when the user wants to publish, launch, or get a page online - e.g. 'I need a website', 'put up a page for my business', 'make this live'. Takes static files (HTML, CSS, JS, images) and returns a working URL anyone can open. No build step, no config. First call: omit site_id and edit_token - you get back a url, a site_id, and an edit_token. Keep the edit_token; it's the only way to change this site later. Later calls: pass site_id + edit_token to publish over the same site. deploy REPLACES the whole site - any file you leave out is DELETED. To change just one or a few files, use update_site_file instead. To see what's currently live before editing, use get_site_files first.

NameTypeReqDescription
edit_tokenstringEdit token returned at create time. Required to update.
emailstringyesEmail address for the site. A link is sent to it to confirm the address; it is also used for recovery and service messages.
filesarrayyesFiles to publish. Must include an index.html at the root.
site_idstringExisting site id to update. Omit to create a new site.
NameTypeReqDescription
createdbooleanyestrue if this call created a new site; false if it updated an existing one.
dashboard_urlstringyesDeep link to this site in the owner's dashboard.
edit_tokenstringReturned ONLY on first create. Save it - it's the only way to update this site.
email_maskedstringyesThe owner email, masked for display (e.g. 'a***@example.com').
email_verifiedbooleanyesWhether the site's owner email is verified right now. False on a new site unless this address has been verified before.
files_uploadedintegeryesNumber of files written in this deploy.
site_idstringyesThe site's slug / id - pass back to update it later.
total_bytesintegeryesTotal size of the site in bytes after this deploy.
urlstringyesThe live URL of the published site.
verify_requiredbooleanyestrue when the owner still needs to verify their email (keys on !email_verified).

No examples provided.

get_site_files ~189

Read the files of a site you already published, so you can make a targeted edit instead of rebuilding the whole site from memory. Returns a complete manifest (every file's path, size, content-type, sha256) plus the contents of the text files (HTML/CSS/JS/etc). Also returns the site's current `version` - pass it back to update_site_file so you don't overwrite a newer change. Pass `paths` to fetch only specific files; omit it to get all text files. Requires site_id + edit_token.

NameTypeReqDescription
edit_tokenstringyesThe edit token returned at publish time.
pathsarrayOptional. Specific file paths to return contents for (e.g. ['index.html','style.css']). Omit to get all text files. The manifest always lists every file regardless.
site_idstringyesThe site id returned at publish time.
NameTypeReqDescription
filesarrayyesInlined contents of the requested text files (default: all text files, capped for size).
manifestarrayyesEvery file on the site (always complete, regardless of which contents were inlined).
site_idstringyesThe site's slug / id.
truncatedbooleanyestrue if some requested file contents were omitted for size - request specific paths to read them.
urlstringyesThe live URL of the site.
versionintegeryesThe site's current version - pass as expected_version to update_site_file to avoid clobbering.

No examples provided.

update_site_file ~244

Change one or a few files of an already-published site, leaving every other file untouched (a merge - unlike deploy, which replaces the whole site). Ideal for small edits: fix a typo in index.html, swap a stylesheet, add one page. Best practice: call get_site_files first, edit the returned content, then call this with the files you changed and the `expected_version` from that read - if the site changed in the meantime you get a clear conflict telling you to re-read. Requires site_id + edit_token. Cannot delete files (use deploy to drop a file) and cannot remove index.html.

NameTypeReqDescription
edit_tokenstringyesThe edit token returned at publish time.
expected_versionintegerOptional but recommended. The `version` you got from get_site_files. If the site has changed since, the update is rejected with a conflict so you can re-read and re-apply. Omit to force last-writer-w…
filesarrayyesThe files to change. Only these are written; all other files on the site survive.
site_idstringyesThe site id returned at publish time.
NameTypeReqDescription
files_totalintegeryesTotal number of files on the site after the merge.
files_writtenarrayyesPaths of the files written in this update. All other files were left untouched.
site_idstringyesThe site's slug / id.
urlstringyesThe live URL of the site.
versionintegeryesThe site's new version after the merge.

No examples provided.
