Configuration

The server requires the following environment variables:

• SEQ_BASE_URL (optional): Your Seq server URL (defaults to ‘http://localhost:8080’)
• SEQ_API_KEY (required): Your Seq API key

seq-ops Skill

This repo includes a Claude skill for Seq log analysis and incident investigation. Once the MCP server is connected, the skill guides Claude through structured investigations — health checks, incident triage, post-deployment monitoring — and produces consistent, actionable reports.

Install the skill:

# From the releases page, download seq-ops.skill, then:
claude skill install seq-ops.skill

Or install directly from this repo:

npx skills add ahmad2x4/mcp-server-seq

The skill automatically activates when you ask things like “morning health check”, “something is broken in prod”, “check the logs for timeouts”, or “investigate the PPSR integration”.

Usage with Claude Code

Run the following command to add the server:

claude mcp add --transport stdio \
  --env SEQ_BASE_URL=http://localhost:5341 \
  --env SEQ_API_KEY=your-api-key \
  seq -- npx -y mcp-seq

To share the configuration with your team, use the --scope project flag (saves to .mcp.json):

claude mcp add --transport stdio --scope project \
  --env SEQ_BASE_URL=http://localhost:5341 \
  --env SEQ_API_KEY=your-api-key \
  seq -- npx -y mcp-seq

Windows users: Replace npx -y mcp-seq with cmd /c npx -y mcp-seq to avoid “Connection closed” errors.

Verify the server is connected by running /mcp inside Claude Code.

Usage with Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "seq": {
      "command": "npx",
      "args": ["-y", "mcp-seq"],
      "env": {
        "SEQ_BASE_URL": "your-seq-url",
        "SEQ_API_KEY": "your-api-key"
      }
    }
  }
}
