An MCP server to operate your Sapiens Sintéticos account from Claude Code, or any MCP client, in your own account. You ask in plain language ("generate an image of this", "write an essay on that") and it does the work, spending your Sinapses (the house credit) and saving to your profile.

Sapiens Sintéticos is an AI prototyping lab. This server is the exoskeleton: image, video, article, voice, music, a personal Repertório (the creative memory the rest reads from), and the community, all from a single conversation.

Account-gated by design

You connect with a Sapiens account (Google or email), no API key, no card. Accounts and login live on the site, never here. No account yet? Create one at sapiensinteticos.com. Every action shows its cost before it runs, and a failed generation is refunded. The remote endpoint is fail-closed: no valid session, nothing runs.

Connect

Claude Code: the plugin. One install brings the house skills, native to Claude Code (they load when the topic matches and show up under /), and the Sapiens server, running on your computer:

/plugin marketplace add inhabitants/sapiens-mcp
/plugin install sapiens-sinteticos@sapiens-sinteticos

Node 18+. On enable, Claude Code asks for optional keys: fal, Kie, WaveSpeed and Replicate. Fill in only the ones you have. Blank, you generate with Sinapses. Filled in, you generate on your own provider credit, with no house margin, and the key stays in your system's credential store. To connect your account, generate a code at /conectar-claude and tell Claude "connect my Sapiens account, code XXXX-XXXX". More in plugins/sapiens-sinteticos.

Remote (any MCP client, streamable HTTP). Point your client at:

https://www.sapiensinteticos.com/api/mcp/mcp

with the header Authorization: Bearer <sessionToken>. Generate the token at sapiensinteticos.com/conectar-claude. Identity is always the bearer, so there is no local login on the remote transport. Keep the www: the bare domain redirects, and the redirect drops the header.

Local (any MCP client, npm / stdio). Your client runs npx -y sapiens-mcp. In Claude Code, without the plugin:

claude mcp add sapiens -- npx -y sapiens-mcp

Node 18+. The backend URL is built in, nothing to configure. Then log in: open /conectar-claude while signed in, generate the code (XXXX-XXXX, valid for 5 minutes), and run sapiens_meta with action: "login" and code: "XXXX-XXXX". The 30-day token is saved to ~/.sapiens-mcp/session.json.

Works in Gemini CLI, Cursor, Antigravity, Claude Code and any MCP-speaking client. Only the way you add it changes.

What you can ask (and the cost in Sinapses)

The Claude side always warns the cost before spending. Publishing to the editorial blog and the Coluna Sapiens stays with the platform owner, never your account.

Troubleshooting

• "sessionToken expired" / "Sapiens account not connected". The 30-day token lapsed or was never saved. Open /conectar-claude signed in, generate a fresh code, and run sapiens_meta action=login code=XXXX-XXXX.
• A tool or a new capability went missing after an update. The client runs via npx -y sapiens-mcp (unpinned) and may be stuck on an old cache. Check what is running with sapiens_meta action=version (binary version, latest on npm, and upToDate). If upToDate:false, clear the npx cache and restart the client. With the plugin: /plugin, Installed tab, Sapiens Sintéticos, Update now, then /reload-plugins.
• "Invalid arguments". The message already names the field that is missing or wrong, redo the call with what it asks. Do not repeat the same failing call (3 failures in a row make the client mark the server unreachable for about a minute, an anti-loop breaker).
• Low balance before generating. sapiens_meta action=credits (or action=subscription for the per-bucket detail) shows what is left before you spend on image, music, or video.

Privacy

The server only talks to the public Sapiens backend (Convex). With your own key (fal, Kie, WaveSpeed or Replicate), generations go from your computer straight to that provider, and each key only ever goes to its own provider's address. Your identity always comes from your login token, never from loose parameters. Each account only touches what is its own.

The house

Sister properties from the same Borderless house:

• sapiensinteticos.com: the studio, and this server's home.
• aitag.app: a curated directory of AI tools (BR and EU). The Sapiens Repertório pulls from this catalog.
• helenai.wtf: Helen, the house's autonomous humanized AI brand (music, chat, comics). The style anchor of Sapiens.
