Uniquity Mcp Server

Uniquity MCP Server

Overview

Uniquity MCP Server is a server that makes the functions of UniquityReporter available to external tools and AI agents via MCP (Model Context Protocol).

UniquityReporter: UniquityReporter

• Enables the analysis functions of UniquityReporter to be called from MCP Host or AI agents.
• Separates core logic and interface to improve maintainability and extensibility.
• Makes it available from various clients through a standardized protocol.

Release Note

• 0.1.0
  • Initial version

MCP Host Settings

Required and Optional Environment Variables

• Required (Must be passed from MCP Host)
  • GITHUB_TOKEN: Token for GitHub API
  • OPENAI_API_KEY: OpenAI API key
  • TAVILY_API_KEY: Tavily API key
• Optional (If not specified, the default values in config/config.js will be used)
  • openaiModel: Name of the OpenAI model to use (e.g., o3-mini, gpt-4.1-nano, etc.)
  • logEnabled: Enable/disable log output (on/off)

Example MCP Host Configuration

{
  "uniquity-mcp": {
    "command": "npx",
    "args": [
      "-y",
      "uniquity-mcp@latest"
    ],
    "env": {
      "GITHUB_TOKEN": "{apikey}",
      "OPENAI_API_KEY": "{apikey}",
      "TAVILY_API_KEY": "{apikey}"
    }
  }
}

• Secrets in env settings are required.
• This MCP does not support report and log file saving.
• If file saving is required, save the standard output to a file on the Host side.

List of Provided Tools (MCP Server)

1. analyze_repository

• Description: Generates a similarity analysis report for the specified GitHub repository. The report is always returned in Markdown format to standard output.
• Return Value: Report body in Markdown format (standard output)

Argument	Type	Required	Description
repositoryUrl	string	Yes	GitHub repository URL to analyze
openaiModel	string	No	Name of the OpenAI model to use (e.g., o3-mini, gpt-4.1-nano, etc.)
logEnabled	string	No	Enable/disable log output (on/off, default: off)

2. list_tools

• Description: Returns a list of tools provided by the MCP Server and their specifications (arguments and return values).
• Return Value: Array of tools available in the MCP Server (including name, description, parameterSchema, returnSchema for each tool)

Argument	Type	Required	Description
None

---

This makes it clear to MCP Hosts and clients "what tools are available" and "how to call them."

Notes

• MCP Server supports standard output only.
• openaiModel and logEnabled can be dynamically specified as tool arguments.
• Optional values can be omitted, and if omitted, the default values of UniquityReporter will be used.

Version Management of Dependency Package (uniquity-reporter)

• The dependency of uniquity-reporter in package.json is specified as ^1.4.4.

  • This allows minor and patch updates to be automatically followed, but major version updates (such as 2.x) will not be automatically followed.
  • If you want to guarantee "always the latest," perform version updates and releases of the MCP Server itself, and recommend users to use npx uniquity-mcp@latest.

• Note on npx Cache Behavior

  • npx caches the retrieved packages and dependencies.
  • If you want to always use the latest version of the package and dependencies, explicitly specify "uniquity-mcp@latest" as in the MCP Host configuration example, and guide users to clear the cache (npx clear-npx-cache, etc.) for safety.

• If there are specification changes or significant updates to the dependency package, promptly version up the MCP Server and announce it in the release notes or README.

Architecture Overview

• This repository manages only the implementation of the MCP Server and depends on the uniquity-reporter npm package for core logic.
• Receives requests from MCP Host, calls UniquityReporter CLI, and returns the results.
• Uses standard input/output (stdin/stdout) based inter-process communication.
• Reports are always output to standard output and are not saved to files.
