Coverity MCP Server

A TypeScript Model Context Protocol (MCP) server that connects AI agents to Black Duck Coverity Connect for static analysis defect management.

Give your AI coding assistant direct access to Coverity projects, streams, and defect data — so it can find issues, understand their root cause via event traces, and fix them in your codebase.

Features

• List projects — browse all Coverity projects you have access to

• List streams — view analysis streams, optionally filtered by project

• Search issues — find defects by stream with filters for checker, impact, status, and pagination

• Get issue details — retrieve full defect info including the event trace (code path leading to the defect) and triage data

• Two transport modes — stdio for Claude Desktop / CLI, HTTP for web-based integrations

Prerequisites

• Node.js >= 20.11.0

• Access to a Coverity Connect instance with REST API enabled

• A Coverity authentication key (generated from your Coverity Connect user settings)

Quick Start

git clone https://github.com/baxishrey/Coverity-MCP-Server-Typescript.git
cd Coverity-MCP-Server-Typescript
npm install
npm run build

Create a .env file from the example:

cp .env.example .env

Edit .env with your Coverity Connect credentials:

COVERITY_HOST=coverity.example.com
COVERITY_PORT=8443
COVERITY_SSL=true
COVERITY_USER=your_username
COVERITY_AUTH_KEY=your_auth_key

Run the server:

npm start          # stdio transport (default)
npm run start:http # HTTP transport on port 3000

Claude Desktop Configuration

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "coverity": {
      "command": "node",
      "args": ["/path/to/Coverity-MCP-Server-Typescript/build/index.js"],
      "env": {
        "COVERITY_HOST": "coverity.example.com",
        "COVERITY_PORT": "8443",
        "COVERITY_SSL": "true",
        "COVERITY_USER": "your_username",
        "COVERITY_AUTH_KEY": "your_auth_key"
      }
    }
  }
}

For HTTP transport mode, use the MCP endpoint URL instead:

{
  "mcpServers": {
    "coverity": {
      "type": "http",
      "url": "http://localhost:3000/mcp"
    }
  }
}

Tools

list_projects

List all Coverity projects the authenticated user can access.

Parameters: none

Returns: project name, key, description, and associated streams.

list_streams

List Coverity streams, optionally filtered by project name.

Returns: stream name, language, description, and parent project.

search_issues

Search for static analysis defects in a Coverity stream.

Returns: CID, checker, type, impact, status, file, and function for each defect.

get_issue_details

Get full details for a specific defect, including the event trace that shows the code path leading to the issue.

Returns: complete defect information with triage data (action, classification, severity, owner) and event chain (step-by-step code path with file and line numbers).

Resources

coverity://server-info

Read-only resource showing the current Coverity server connection configuration (host, port, SSL, user). Does not expose the authentication key.

Typical Workflow

A code agent using this server would typically:

1. list_projects — discover available projects

2. list_streams — find the relevant stream for the codebase

3. search_issues — find defects (filter by impact: "High" for critical ones)

4. get_issue_details — get the event trace for a specific defect

5. Read the source file at the reported location and apply a fix based on the event trace

Adding a New Tool

Create a file in src/tools/ — it will be auto-discovered at startup:

import { z } from "zod";
import type { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import type { RegisterableModule } from "../registry/types.js";

export default {
  type: "tool",
  name: "my-tool",
  description: "Does something useful",
  register(server: McpServer) {
    server.tool("my_tool", "Description", {
      param: z.string().describe("A parameter"),
    }, async ({ param }) => {
      return { content: [{ type: "text", text: `Result: ${param}` }] };
    });
  },
} satisfies RegisterableModule;
