Genna MCP Connector

What is the Genna connector

The Genna connector lets you manage your brands’ social media content directly from your AI assistant, using the Model Context Protocol (MCP). With it, your assistant can plan, draft, and design posts for your brands, organize your media gallery, research reference accounts, read your own pages’ performance analytics, and — only when you say so — publish or schedule content to your connected social channels.

It is a remote MCP server operated by Genna Technologies, Inc. at https://mcp.genna.co/mcp, using the Streamable HTTP transport and OAuth 2.1 authentication. It works with any MCP-compatible AI assistant or agent that supports remote connectors, in chat apps and developer tools alike.

Using the connector requires a Genna account. Everything the connector does is governed by the Genna Terms of Service and the Genna Privacy Policy.

How it works: you stay in control

Genna is an assistive tool, and the connector follows the same principles as the Genna app:

• Drafts first. Creating a post produces a draft inside your Genna workspace — nothing is posted anywhere. You can review every draft in the chat or open it in the Genna editor.
• Human review and approval. Content reaches a social network only when you explicitly ask your assistant to publish or schedule it. The connector marks publishing tools as destructive so compliant assistants ask for your confirmation before calling them.
• Scoped permissions. Publishing requires a separate mcp:publish permission that you grant (or withhold) when you connect. Without it, the connector can create and edit drafts but can never post.
• Your accounts only. The connector acts only on brands in your Genna workspace and social accounts you have connected and are authorized to manage.

Connect your AI assistant to Genna

Chat assistants (custom connectors)

1. Open your assistant’s connectors or integrations settings and choose to add a custom/remote MCP connector.
2. Enter the endpoint: https://mcp.genna.co/mcp.
3. You are redirected to Genna’s secure sign-in and consent screen. Sign in, choose which brands the connector may access, and which permissions to grant (read, write, publish).
4. Approve. Your assistant is now connected — start a chat and ask it about your brands.

CLI and developer MCP clients

Add the connector with your client’s standard flow, using the endpoint https://mcp.genna.co/mcp and the Streamable HTTP transport. The OAuth flow starts automatically on first use.

Advanced users can alternatively authenticate with a Genna API key created in the Genna app, sent as a Bearer token in the Authorization header.

Disconnecting

You can revoke the connector’s access at any time: remove the connector in your assistant’s settings, or revoke the grant from your Genna account settings. Access grants expire automatically after 12 months, and idle refresh tokens after 90 days.

Permissions & security

• OAuth 2.1 with authorization-code flow and mandatory PKCE (S256), served over TLS with certificates from recognized authorities.
• Granular scopes: mcp:read (view brands, posts, analytics), mcp:write (create and edit drafts, upload media), mcp:publish (publish or schedule to connected channels). Unknown or empty scopes are rejected.
• Brand allowlist: each grant or API key can be restricted to specific brands; ownership is re-verified on every call.
• Short-lived tokens: access tokens expire after 30 minutes; refresh tokens rotate on every use, and reuse of an old token revokes the entire grant.
• Credentials hashed at rest: API keys and refresh tokens are stored only as SHA-256 hashes.
• Full audit trail: every tool call is recorded in your account’s activity history — identifiers only, never your conversation content.

What you can do

Design rendering in the design workflow

The Genna connector is design-focused software: it produces social post designs — slides with your brand’s identity, typography, and layout:

• There is no standalone image generator. No tool takes a free-form prompt and returns an image.
• Images are only ever rendered for the slides of an existing post draft — the post’s title, caption, per-slide texts, format, and brand identity drive the visuals.
• Per-slide refinements (adjust, regenerate, replace) operate on one slide of one post and are bounded by revision limits.
• Uploading media to the gallery ingests files you already have; it generates nothing.

In short

Genna generates images the way a slide-design tool does: as part of producing a designed asset you asked for — never as a general-purpose image generation service.

Publishing safeguards

• Publishing and scheduling require the separate mcp:publish permission.
• Both tools are annotated as destructive, so compliant assistants confirm with you before calling them.
• Publishing fails safely if the brand has no connected social account.
• Every publish is additionally recorded as a dedicated audit event in your account history.
• Scheduled posts can be reviewed and managed in the Genna app before they go out.

Data access & privacy

The connector accesses only the data needed to perform the action you asked for, within the brands you allowed:

• Accessed on request: your brand profiles, posts and drafts, media gallery, connected social accounts, your own pages’ analytics, your products, audience personas, saved reference accounts, and industry news items.
• Never accessed: your conversations with your assistant, its memory, or uploaded files beyond the tool parameters the assistant sends; other users’ workspaces; private content of any third-party account.
• Logging: tool calls are audited with identifiers only — no conversation data and no generated content is stored in audit logs.
• Media uploads go directly to Genna’s cloud storage over pre-signed URLs; server-side URL fetches are validated to block private networks and unsafe schemes.

How Genna collects, uses, and retains personal information is described in the Genna Privacy Policy. For data-protection questions, contact privacy@genna.co.

Usage limits & credits

• Requests are rate-limited per credential to keep the service healthy.
• Rendering a post’s images debits one generation credit from your Genna plan, exactly as in the Genna app. The assistant is informed of this in the tool description, and the connector fails with a clear message if your plan has no credits left.
• Per-slide AI refinements draw on each slide’s revision allowance; swapping in a gallery image is always free.
• Responses are kept compact by design; media previews are size-capped, and you can request a single slide instead of a full post to save tokens.

Example prompts

• “Create an Instagram carousel for my brand about our new product launch — suggest a few ideas first, then draft it and show me the images before anything is published.”
• “Here are three photos from today’s event — post them as a carousel on my Instagram with a caption you write, and schedule it for tomorrow at 9am.”
• “How did my last 10 posts perform? Which format got the best save rate, and what should I post next based on that?”
• “Make slide 2’s image warmer and remove the text overlay, then publish the post.”
