Codebase Memory MCP License: MIT Terms Explained

Codebase Memory MCP is released under the MIT License, a permissive open-source license that grants unrestricted rights to use, modify, distribute, and sublicense the software, provided that the original copyright notice and license terms are preserved in all copies.

The DeusData/codebase-memory-mcp repository provides a Memory-Code-Parser (MCP) engine for indexing and querying source code with ZSTD compression. Understanding the codebase memory MCP license ensures compliant integration into both proprietary and open-source projects.

MIT License Permissions

The MIT License governing this codebase grants four fundamental rights:

• Free use – No restrictions on application type, including commercial products.
• Modification – Freedom to alter any portion of the source code, including components in src/ and internal/cbm/.
• Distribution – Authority to share original or derivative versions, provided the LICENSE file and copyright notice accompany the distribution.
• Sublicensing – Ability to incorporate the code into projects under different license terms.

The software is provided "as is" without warranty of any kind, as stated in the LICENSE file at the repository root.

License File Location and Structure

The complete legal text resides in the repository's LICENSE file. This document governs all original source code, including:

• src/ – Core MCP implementation and engine logic
• tests/ – Test suite ensuring correctness and stability
• internal/cbm/ – Internal components, including the native ZSTD storage backend

All files within these directories fall under the MIT License unless otherwise specified.

Third-Party Dependencies

The repository includes a vendored/ directory containing third-party libraries bundled with the project. These components maintain their own respective licenses, which may differ from the MIT terms covering the primary codebase. Review individual license files within vendored/ before redistribution to ensure full compliance.

Code Example Under MIT Terms

The following C code demonstrates basic initialization using the cbm.h API. This example, like all files in the repository, is subject to MIT License terms requiring attribution:

/* example.c – Simple integration of Codebase Memory MCP */
#include "cbm.h"

int main(void) {
    /* Initialize the MCP engine */
    cbm_engine *engine = cbm_engine_new();
    if (!engine) {
        fprintf(stderr, "Failed to create MCP engine\n");
        return 1;
    }

    /* Load a source file into memory */
    const char *path = "example.c";
    cbm_source *src = cbm_load_source(engine, path);
    if (!src) {
        fprintf(stderr, "Unable to load %s\n", path);
        cbm_engine_free(engine);
        return 1;
    }

    /* Perform a simple query */
    const char *query = "function";
    cbm_results *res = cbm_query(engine, src, query);
    printf("Found %zu occurrences of \"%s\"\n", res->count, query);

    /* Clean up */
    cbm_results_free(res);
    cbm_source_free(src);
    cbm_engine_free(engine);
    return 0;
}

When distributing applications containing this code, you must include the original MIT License notice covering the cbm.h header and implementation files.

Summary

• Codebase Memory MCP from DeusData is distributed under the MIT License.
• The LICENSE file at the repository root contains the full legal text applicable to src/, tests/, and internal/cbm/.
• Permissive terms allow commercial use, modification, and private or public distribution with minimal requirements.
• Attribution required – All copies must retain the original copyright notice and license text.
• Third-party code in vendored/ may have separate licensing terms that require additional compliance steps.

Frequently Asked Questions

Is Codebase Memory MCP free for commercial use?

Yes. The MIT License explicitly permits commercial applications without royalty or usage fees. You may integrate the MCP engine into proprietary products, including functions from src/ and the ZSTD storage backend in internal/cbm/, provided you include the original copyright notice and license text.

What are the requirements when redistributing modified versions?

When distributing modified versions of the codebase, you must include the original MIT License text and copyright notice found in the LICENSE file. This requirement applies whether you distribute source code or compiled binaries containing modified versions of cbm_engine_new() or other components.

Does the MIT license cover dependencies in the vendored/ directory?

No. The vendored/ directory contains third-party libraries that maintain their own separate licenses. While the core MCP functionality in src/ and internal/cbm/ is MIT-licensed, you must review individual license files within vendored/ to ensure compliance when redistributing those specific components.

Where can I find the full license text in the repository?

The complete MIT License text is located in the LICENSE file at the root of the DeusData/codebase-memory-mcp repository. This file governs all source code except where noted in third-party subdirectories.
