Visual setup and architecture guide for App

01 // How It Works & Runtime Architecture

Provides a deterministic data integration layer for conversational agents. It connects to target data sources, executes parameterized queries against structured schemas, and formats tabular and vector results into concise token-efficient payloads for downstream reasoning.

04 // Client Configuration (claude_desktop_config.json)

{
  "mcpServers": {
    "app": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-app"
      ]
    }
  }
}

Paste into your client configuration file (e.g. ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%/Claude/claude_desktop_config.json on Windows).

05 // Step-by-Step Installation

Verified Process
  1. 1

    Clone the upstream repository from GitHub: https://github.com/reactive-resume/app

  2. 2

    Review prerequisites and install runtime dependencies using pip or npm as outlined in the repository documentation

  3. 3

    Set necessary API keys and configuration parameters in your local environment

  4. 4

    Invoke the skill from your AI agent pipeline or command-line interface to verify execution

06 // Execution Boundaries & Security Safeguards

● Context Protection

Keeps heavy parsing and raw file structures external to the LLM. Only sanitized excerpts and structured returns are injected into agent memory turns.

● Directory Allowlisting

Enforce explicit directory allowlists and permission scopes in client configuration to ensure autonomous tool calls never breach system boundaries.

● Process Isolation

Executes in an isolated local child process communicating strictly over JSON-RPC via stdio with explicit process timeouts.

07 // Frequently Asked Questions

FAQ Schema Included

What is App and how does it empower AI agents?

App is an open-source data capability designed for AI clients and autonomous agents. A one-of-a-kind resume builder that keeps your privacy in mind. Completely secure, customizable, portable, open-source and free forever. Try it out today!.

How do I install and configure App?

Follow the step-by-step installation: 1) Verify your runtime (Node.js 18+), 2) Add the configuration snippet into your AI client settings (e.g. claude_desktop_config.json), 3) Restart the client to initialize tool execution.

Which AI clients and developer harnesses support App?

App is compatible with all AI tools supporting tool-calling and the Model Context Protocol (MCP), including Claude Desktop, Cursor, Claude Code CLI, Windsurf, OpenCode, and custom agent runtimes.

What security boundaries and sandboxing safeguards does App enforce?

App executes locally with strict directory allowlists and permission scopes. Heavy parsing and raw file structures stay external to the LLM context window to prevent memory saturation and unauthorized access.

Is App free and open source?

Yes, App is published under the MIT open-source license. You can inspect the source code and contribute on GitHub at https://github.com/reactive-resume/app.
