## Overview

#### Purpose and Entry Points
This is a small Node.js-oriented repository with a root server entry point and a workspace-local application script. No README content or source details are provided, so business behavior and framework choice are not established.

- Root runtime entry: `server.js`
- Workspace application module: `workspace/app.js`
- Dependency manifest/lockfile: `package.json`, `package-lock.json`

#### Runtime Bootstrap
`server.js` is the likely process bootstrap: it should own application startup, listener/process lifecycle, and delegation into application code. `workspace/app.js` is the likely implementation boundary for the workspace application logic.

Control flow is expected to begin at `server.js` and enter `workspace/app.js`; confirm actual imports and npm scripts before modifying startup behavior.

#### Application Boundary
`workspace/app.js` is the central application boundary available in the tree. It should be treated as the location for request handling, command handling, or other application orchestration, depending on what `server.js` invokes.

The repository does not expose separate route, service, persistence, or domain directories. Consequently, these concerns may currently be colocated in:

- `workspace/app.js`
- `server.js`

#### Workspace Data Surface
The `workspace/` directory contains text artifacts that may be application inputs, outputs, or scratch/state files:

- `workspace/notes.txt`
- `workspace/test.txt`
- `workspace/todo.txt`

`workspace/{{$json.filename}}` appears to be a literal templated filename rather than a resolved generated file. Any workflow that writes workspace files should establish whether this is intentional template syntax, an automation artifact, or a filename bug.

#### Dependencies and Infrastructure
Node package metadata is present:

- `package.json`
- `package-lock.json`

These files define the material runtime dependencies and available package scripts, but their contents are not supplied. No database, queue, cloud service, container setup, CI configuration, or frontend asset pipeline is visible in the provided tree.

#### Important Boundaries
The principal boundaries are:
1. **Process/bootstrap boundary:** `server.js` starts and configures the runtime.
2. **Application boundary:** `workspace/app.js` performs the application’s core work.
3. **Filesystem boundary:** application behavior may read or write files under `workspace/`.
4. **Dependency boundary:** external packages are declared through `package.json` and locked by `package-lock.json`.

Before extending the system, inspect `package.json`, `server.js`, and `workspace/app.js` to determine the actual launch command, module wiring, exposed interface, and workspace-file semantics.

Main entry points: [`package.json`](https://github.com/anu5565/mcp-prj/blob/main/package.json) (Package Manifest), [`server.js`](https://github.com/anu5565/mcp-prj/blob/main/server.js) (Server Bootstrap), [`workspace/app.js`](https://github.com/anu5565/mcp-prj/blob/main/workspace/app.js) (Application Module), [`package-lock.json`](https://github.com/anu5565/mcp-prj/blob/main/package-lock.json) (Dependency Lockfile)
