**The main entry point for the DeusData/codebase-memory-mcp application is located in [`src/main.c`](https://github.com/DeusData/codebase-memory-mcp/blob/main/src/main.c) at the `main` function defined on line 654.**

The **DeusData/codebase-memory-mcp** repository is a C-based project that requires understanding its startup sequence to extend or debug the application. The program’s execution begins in a specific source file that handles initialization and argument parsing before launching the core logic.

## Locating the Main Entry Point in src/main.c

The definitive start of execution resides in the **[`src/main.c`](https://github.com/DeusData/codebase-memory-mcp/blob/main/src/main.c)** file. This C source file contains the standard entry point that the operating system calls when launching the executable.

### The main Function Implementation

At line 654 of [`src/main.c`](https://github.com/DeusData/codebase-memory-mcp/blob/main/src/main.c), you will find the function definition that serves as the application’s entry point:

```c
int main(int argc, char **argv) {
    // initialization, argument parsing, and program startup
    …
    return exit_code;
}

```

This function accepts command-line arguments through the standard `argc` and `argv` parameters, processes them, and returns an integer exit code to the shell. The ellipsis (`…`) in the source indicates where the application performs its specific initialization routines, memory allocation, and service startup before entering the main execution loop.

### Build Configuration with Makefile.cbm

The project's build system, defined in **`Makefile.cbm`**, compiles [`src/main.c`](https://github.com/DeusData/codebase-memory-mcp/blob/main/src/main.c) and links the `main` function as the executable’s entry point. When you run the build command (typically `make -f Makefile.cbm`), the linker resolves the `main` symbol defined in [`src/main.c`](https://github.com/DeusData/codebase-memory-mcp/blob/main/src/main.c) as the program's starting address.

## Understanding the Entry Point Structure

The `main` function in [`src/main.c`](https://github.com/DeusData/codebase-memory-mcp/blob/main/src/main.c) follows the standard C program structure. It handles the transition from operating system control to application logic by:

1. Parsing command-line arguments passed via `argc` and `argv`
2. Initializing data structures and memory pools
3. Setting up the MCP (Model Context Protocol) server context
4. Returning an appropriate exit status to the caller

```c
/* src/main.c - simplified structure */
int main(int argc, char **argv) {
    int exit_code = 0;
    
    /* Parse configuration from CLI args */
    // ...
    
    /* Initialize codebase memory service */
    // ...
    
    return exit_code;
}

```

## Supporting Documentation and Files

While [`src/main.c`](https://github.com/DeusData/codebase-memory-mcp/blob/main/src/main.c) contains the executable entry point, the **[`README.md`](https://github.com/DeusData/codebase-memory-mcp/blob/main/README.md)** file provides high-level overview of the repository structure and build instructions. Refer to this file for dependencies and compilation prerequisites before attempting to build from `Makefile.cbm`.

## Summary

- The **main entry point** for DeusData/codebase-memory-mcp is located in [`src/main.c`](https://github.com/DeusData/codebase-memory-mcp/blob/main/src/main.c) at line 654.
- The entry function uses the standard signature **`int main(int argc, char **argv)`**.
- **`Makefile.cbm`** handles the compilation and linking process that establishes this function as the program start.
- The `main` function manages initialization, argument parsing, and returns an exit code to the operating system.

## Frequently Asked Questions

### Where is the main entry point defined in DeusData/codebase-memory-mcp?

The main entry point is defined in [`src/main.c`](https://github.com/DeusData/codebase-memory-mcp/blob/main/src/main.c) at line 654. This file contains the `main` function that the operating system executes when launching the application binary.

### What is the function signature of the main entry point?

The function signature is `int main(int argc, char **argv)`. This standard C signature accepts an argument count and argument vector, enabling the program to process command-line inputs before initializing the MCP server components.

### How is the entry point compiled into the executable?

The **`Makefile.cbm`** build script compiles [`src/main.c`](https://github.com/DeusData/codebase-memory-mcp/blob/main/src/main.c) and links it with other object files. The linker specifically resolves the `main` symbol in [`src/main.c`](https://github.com/DeusData/codebase-memory-mcp/blob/main/src/main.c) as the entry point for the final binary, creating the executable that starts at this function.

### Are there any initialization routines before the main logic runs?

Yes. Inside the `main` function at line 654, the code performs initialization steps including argument parsing, memory allocation, and service setup before transitioning to the primary application logic. These routines prepare the codebase memory MCP environment for operation.
