ai-validation-mcp

AI Validation MCP Server

Independent AI code validation service — analyzes your tests for bias, missing edge cases, and coverage gaps. Works as an MCP server for AI coding agents and IDEs.

Why

AI-generated code increases production incidents 43% YoY. General-purpose assistants generate tests as a side effect, not as a core function. This server provides specialized, independent validation — a second opinion on your test quality.

Installation

npm install ai-validation-mcp

MCP Configuration

Add to your MCP client config (e.g. claude_desktop_config.json):

{
  "mcpServers": {
    "ai-validation": {
      "command": "npx",
      "args": ["-y", "ai-validation-mcp"],
      "env": {
        "ANTHROPIC_API_KEY": "your-key-here"
      }
    }
  }
}

Requires an Anthropic API key for analysis.

Tools

validate_tests

Analyze existing tests for bias, missing edge cases, and quality issues.

Parameter	Type	Required	Description
sourceCode	string	Yes	The source code to validate against
testCode	string	Yes	The existing test code to analyze
language	string	No	Programming language (default: typescript)

Returns: bias warnings, missing edge case suggestions, overall quality score.

suggest_edge_cases

Suggest comprehensive edge cases for a given function.

Parameter	Type	Required	Description
sourceCode	string	Yes	The source code to analyze
language	string	No	Programming language (default: typescript)

Returns: categorized edge cases (happy path, error handling, boundary, type coercion, integration).

coverage_gap_analysis

Identify untested code paths, branches, and logic gaps.

Parameter	Type	Required	Description
sourceCode	string	Yes	The source code to analyze
testCode	string	Yes	The existing test code to evaluate
language	string	No	Programming language (default: typescript)

Returns: coverage score, gap details, suggested tests to close gaps.

Modes

• --cached (default) — Uses saved responses from ./fixtures/. No API calls.
• --live — Real Anthropic API calls. Overwrites fixtures.
