Cloud App Store

Manage the Flow Nexus application marketplace: discover, publish, deploy, and analyze applications and templates.

Quick Start

// Search for authentication apps
const apps = await mcp__flow-nexus__app_search({
  search: "authentication",
  category: "backend",
  featured: true
});

// Deploy a template
await mcp__flow-nexus__template_deploy({
  template_name: "express-api-starter",
  deployment_name: "my-api",
  variables: {
    api_key: "your_api_key",
    database_url: "postgres://..."
  }
});

// Publish your own app
await mcp__flow-nexus__app_store_publish_app({
  name: "My Auth Service",
  description: "JWT-based authentication microservice",
  category: "backend",
  source_code: sourceCode,
  tags: ["auth", "jwt", "express"]
});

MCP Tools Reference

App Discovery

// Search apps
mcp__flow-nexus__app_search({
  search: "query string",      // Search term
  category: "backend",         // Category filter
  featured: true,              // Featured apps only

Usage Examples

Example 1: Finding and Deploying an API Template

// Search for API templates
const templates = await mcp__flow-nexus__template_list({
  category: "backend",
  featured: true
});

// Find the Express starter
const expressTemplate = templates.templates.find(
  t => t.name.includes("express")
);

// Get template details
const details = await mcp__flow-nexus__template_get({
  template_id: expressTemplate.id
});

console.log("Required variables:", details.variables);

// Deploy the template
const deployment = await mcp__flow-nexus__template_deploy({
  template_id: expressTemplate.id,
  deployment_name: "my-express-api",
  variables: {
    database_url: process.env.DATABASE_URL,
    jwt_secret: process.env.JWT_SECRET,
    port: "3000"
  },
  env_vars: {
    NODE_ENV: "production"
  }
});

console.log(`Deployed at: ${deployment.url}`);

Example 2: Publishing a New Application

// Prepare your application
const sourceCode = `
const express = require('express');
const jwt = require('jsonwebtoken');

const app = express();
app.use(express.json());

// JWT authentication middleware
const authenticate = (req, res, next) => {
  const token = req.headers.authorization?.split(' ')[1];
  if (!token) return res.status(401).json({ error: 'Unauthorized' });

  try {
    req.user = jwt.verify(token, process.env.JWT_SECRET);
    next();
  } catch {
    res.status(401).json({ error: 'Invalid token' });
  }
};

// Routes
app.post('/login', (req, res) => {
  const { username, password } = req.body;
  // Authentication logic
  const token = jwt.sign({ username }, process.env.JWT_SECRET);
  res.json({ token });
});

app.get('/protected', authenticate, (req, res) => {
  res.json({ message: 'Protected data', user: req.user });
});

module.exports = app;
`;

// Publish to app store
const published = await mcp__flow-nexus__app_store_publish_app({
  name: "JWT Auth Service",
  description: "A complete JWT authentication service with Express.js. Includes login, token verification, and protected route middleware.",
  category: "backend",
  source_code: sourceCode,
  version: "1.0.0",
  tags: ["authentication", "jwt", "express", "middleware", "security"],
  metadata: {
    author: "Your Name",
    license: "MIT",
    repository: "https://github.com/yourname/jwt-auth-service"
  }
});

console.log(`App published with ID: ${published.app_id}`);

Example 3: Analyzing App Performance

// Get your app's analytics
const analytics = await mcp__flow-nexus__app_analytics({
  app_id: "your_app_id",
  timeframe: "30d"
});

console.log(`
App Performance Report (Last 30 Days):
- Total Downloads: ${analytics.downloads}
- Active Users: ${analytics.active_users}
- Average Rating: ${analytics.rating}/5
- Revenue: ${analytics.revenue} rUv credits
`);

// Get market trends
const market = await mcp__flow-nexus__market_data();

console.log(`
Market Overview:
- Total Apps: ${market.total_apps}
- Total Downloads: ${market.total_downloads}
- Trending Categories: ${market.trending.categories.join(', ')}
`);

Example 4: Managing Installed Apps

// List installed apps
const installed = await mcp__flow-nexus__app_installed({
  user_id: "your_user_id"
});

for (const app of installed.installed_apps) {
  // Get details for each installed app
  const details = await mcp__flow-nexus__app_get({
    app_id: app.app_id
  });

  console.log(`${details.name} v${app.version} - Installed: ${app.installed_at}`);
}

Execution Checklist

Integration Points

With Sandboxes

// Deploy template to sandbox for testing
const sandbox = await mcp__flow-nexus__sandbox_create({
  template: "node"
});

await mcp__flow-nexus__template_deploy({
  template_name: "express-api-starter",
  variables: { sandbox_id: sandbox.sandbox_id }
});

With Payments

// Track app revenue
const balance = await mcp__flow-nexus__ruv_balance({
  user_id: "publisher_id"
});

// Revenue from published apps appears in balance
