Codelogic MCP Server

What is Codelogic MCP Server about?

Codelogic MCP Server offers two impact‑analysis tools—codelogic-method-impact and codelogic-database-impact—that query CodeLogic’s backend APIs to determine how changes to code methods or database entities affect a project. These tools are exposed via the Model Context Protocol (MCP) so AI assistants (e.g., Copilot, Claude, Cursor) can invoke them automatically during code suggestions.

How to use Codelogic MCP Server?

1. Install Astral uv (or uvx) as the runtime.
2. Add an MCP server entry to your IDE’s mcp.json (VS Code, Cursor, Claude Desktop, Windsurf, etc.).
3. Provide required environment variables (CODELOGIC_SERVER_HOST, CODELOGIC_USERNAME, CODELOGIC_PASSWORD, CODELOGIC_WORKSPACE_NAME, optional CODELOGIC_DEBUG_MODE).
4. Restart the IDE; the tools become available in the AI assistant’s tool palette.
5. Prompt the assistant to analyze a method, class, or database entity; the server returns impact data that the assistant can surface to the user.

Key features of Codelogic MCP Server

• Method impact analysis – evaluates ripple effects of changes to a specific method within a class.
• Database impact analysis – evaluates effects on tables, views, or columns.
• Cross‑IDE configuration – ready‑to‑use snippets for VS Code, Cursor, Claude Desktop, Windsurf.
• Debug mode – optional detailed logs and raw impact JSON for troubleshooting.
• Version pinning – specify exact package version via codelogic-mcp-server@<version>.
• Compatibility notes – v0.4.0+ requires CodeLogic API ≥ 25.10.0.

Use cases of Codelogic MCP Server

• Safe refactoring – quickly verify that renaming a method won’t break dependent code.
• Database schema evolution – assess downstream impacts before altering columns or tables.
• Code review assistance – AI reviewers can automatically surface impact summaries.
• On‑the‑fly debugging – developers can ask the assistant why a change caused a failure, with impact data supplied instantly.

FAQ from the Codelogic MCP Server

Q: Which languages are supported? A: The server is intended for Java, JavaScript/TypeScript, and C# (.NET) codebases. It does not support Python or other languages.

Q: Do I need a CodeLogic account? A: Yes. Set CODELOGIC_USERNAME, CODELOGIC_PASSWORD, and CODELOGIC_SERVER_HOST in the env block.

Q: What if I am on macOS and uvx fails? A: Use the workaround detailed in the README – replace uvx with uv and adjust the command arguments accordingly.

Q: How can I enable detailed logs? A: Set CODELOGIC_DEBUG_MODE to true. Log files appear in the OS temporary directory under codelogic-mcp-server.

Q: Can I pin a specific version? A: Yes. Change the args entry to codelogic-mcp-server@<semver>.

codelogic-mcp-server

An MCP Server to utilize Codelogic's rich software dependency data in your AI programming assistant.

Components

Tools

The server implements two tools:

• codelogic-method-impact: Pulls an impact assessment from the CodeLogic server's APIs for your code.
  • Takes the given "method" that you're working on and its associated "class".
• codelogic-database-impact: Analyzes impacts between code and database entities.
  • Takes the database entity type (column, table, or view) and its name.

Install

Pre Requisites

The MCP server relies upon Astral UV to run, please install

MacOS Workaround for uvx

There is a known issue with uvx on MacOS where the CodeLogic MCP server may fail to launch in certain IDEs (such as Cursor), resulting in errors like: See issue #11

Failed to connect client closed

This appears to be a problem with Astral uvx running on MacOS. The following can be used as a workaround:

1. Clone this project locally.
2. Configure your mcp.json to use uv instead of uvx. For example:

{
  "mcpServers": {
    "codelogic-mcp-server": {
      "type": "stdio",
      "command": "<PATH_TO_UV>/uv",
      "args": [
        "--directory",
        "<PATH_TO_THIS_REPO>/codelogic-mcp-server-main",
        "run",
        "codelogic-mcp-server"
      ],
      "env": {
        "CODELOGIC_SERVER_HOST": "<url to the server e.g. https://myco.app.codelogic.com>",
        "CODELOGIC_USERNAME": "<my username>",
        "CODELOGIC_PASSWORD": "<my password>",
        "CODELOGIC_WORKSPACE_NAME": "<my workspace>",
        "CODELOGIC_DEBUG_MODE": "true"
      }
    }
  }
}

3. Restart Cursor.
4. Ensure the Cursor Global Rule for CodeLogic is in place.
5. Open the MCP tab in Cursor and refresh the codelogic-mcp-server.
6. Ask Cursor to make a code change in an existing class. The MCP server should now run the impact analysis successfully.

Configuration for Different IDEs

Visual Studio Code Configuration

To configure this MCP server in VS Code:

1. First, ensure you have GitHub Copilot agent mode enabled in VS Code.

2. Create a .vscode/mcp.json file in your workspace with the following configuration:

{
  "servers": {
    "codelogic-mcp-server": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "codelogic-mcp-server@latest"
      ],
      "env": {
        "CODELOGIC_SERVER_HOST": "<url to the server e.g. https://myco.app.codelogic.com>",
        "CODELOGIC_USERNAME": "<my username>",
        "CODELOGIC_PASSWORD": "<my password>",
        "CODELOGIC_WORKSPACE_NAME": "<my workspace>",
        "CODELOGIC_DEBUG_MODE": "true"
      }
    }
  }
}

Note: On some systems, you may need to use the full path to the uvx executable instead of just "uvx". For example: /home/user/.local/bin/uvx on Linux/Mac or C:\Users\username\AppData\Local\astral\uvx.exe on Windows.

3. Alternatively, you can run the MCP: Add Server command from the Command Palette and provide the server information.

4. To manage your MCP servers, use the MCP: List Servers command from the Command Palette.

5. Once configured, the server's tools will be available to Copilot agent mode. You can toggle specific tools on/off as needed by clicking the Tools button in the Chat view when in agent mode.

6. To use the Codelogic tools in agent mode, you can specifically ask about code impacts or database relationships, and the agent will utilize the appropriate tools.

Pinning the version

instead of using the latest version of the server, you can pin to a specific version by changing the args field to match the version in pypi e.g.

    "args": [
      "codelogic-mcp-server@0.2.2"
    ],

Version Compatibility

This MCP server has the following version compatibility requirements:

• Version 0.3.1 and below: Compatible with all CodeLogic API versions
• Version 0.4.0 and above: Requires CodeLogic API version 25.10.0 or greater

If you're upgrading, make sure your CodeLogic server meets the minimum API version requirement.

Debug Logging

When CODELOGIC_DEBUG_MODE=true, debug files are written to the system temporary directory:

• Windows: %TEMP%\codelogic-mcp-server (typically C:\Users\{username}\AppData\Local\Temp\codelogic-mcp-server)
• macOS: /tmp/codelogic-mcp-server (or $TMPDIR/codelogic-mcp-server if set)
• Linux: /tmp/codelogic-mcp-server (or $TMPDIR/codelogic-mcp-server if set)

Debug files include:

• timing_log.txt - Performance timing information
• impact_data_*.json - Raw impact analysis data for troubleshooting

Finding your log directory:

import tempfile
import os
print("Log directory:", os.path.join(tempfile.gettempdir(), "codelogic-mcp-server"))

Testing

Running Unit Tests

The project uses unittest for testing. You can run unit tests without any external dependencies:

python -m unittest discover -s test -p "unit_*.py"

Unit tests use mock data and don't require a connection to a CodeLogic server.

Integration Tests (Optional)

If you want to run integration tests that connect to a real CodeLogic server:

1. Copy test/.env.test.example to test/.env.test and populate with your CodeLogic server details
2. Run the integration tests:

python -m unittest discover -s test -p "integration_*.py"

Note: Integration tests require access to a CodeLogic server instance.
