SupraPrompt.ai — Desktop Extension (.mcpb)

Connect SupraPrompt.ai to Claude (Cowork & Desktop) and turn rough product-marketing briefs into precision AI Briefings — battle cards, positioning, launch messaging, buyer personas, competitive intel and more — without leaving Claude.

Requires a paid SupraPrompt.ai plan. The free tier is web-app only.

Install (Cowork / Claude Desktop)

1. Create an API key at supraprompt.ai/mcp (starts with sp_live_).

2. Download SupraPrompt.mcpb (this repo / the latest release).

3. Open Claude Settings → Extensions and drag the .mcpb in (or double-click it).

4. When prompted, paste your API key. It's stored in your OS keychain — never in plain config.

5. Ask: "Use SupraPrompt to list available content types."

No JSON editing, no environment variables, no OAuth.

How it works

.mcpb bundles only run local stdio servers, but the SupraPrompt MCP server is remote HTTPS (https://supraprompt.ai/api/mcp). So this extension ships a tiny zero-dependency stdio→HTTPS bridge (server/index.mjs): Claude launches it locally, it reads the SUPRAPROMPT_API_KEY injected from the prompted user_config, and forwards every MCP message to the server with an Authorization: Bearer header.

Tools

Build

npm install        # dev-only: @anthropic-ai/mcpb
npm run validate   # schema-check manifest.json
npm run pack       # produces SupraPrompt.mcpb

Distribution tracks

Both authenticate to the same endpoint with the same sp_live_… key.

Notes

• The published supraprompt-mcp npm package is deprecated (it targets a stale endpoint and returns HTML). Use this .mcpb instead.

• Node ≥ 18 (Claude bundles a runtime; no local Node install required).
