ahmad2x4 mcp server seq

MCP Server for Seq's API endpoints for interacting with your logging and monitoring system. This server provides comprehensive access to Seq's API features through the Model Context Protocol.

• get_signals - Fetch signals with filtering options
  • Filter by owner ID
  • Filter shared/private signals
  • Support for partial matches

• get_events - Retrieve events with extensive filtering options
  • Filter by signal IDs
  • Custom filter expressions
  • Configurable event count (max 50)
  • Flexible time range options
  • Date range filtering

• get_alert_state - Retrieve the current state of alerts

• signals - List all shared signals with detailed information
  • Signal ID
  • Title
  • Description
  • Sharing status
  • Owner information

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

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".

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.

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"
      }
    }
  }
}

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run dev

Run tests:

npm run test-script

The get-events tool supports the following time range options:

• 1m - Last minute
• 15m - Last 15 minutes
• 30m - Last 30 minutes
• 1h - Last hour
• 2h - Last 2 hours
• 6h - Last 6 hours
• 12h - Last 12 hours
• 1d - Last day
• 7d - Last 7 days
• 14d - Last 14 days
• 30d - Last 30 days

Install globally via npm:

npm install -g mcp-seq

Or use directly with npx — no installation required (as shown in the configuration examples above).

Since MCP servers communicate over stdio, debugging can be challenging. The server implements proper error handling and logging for all operations. You can run the test script to verify functionality:

npm run test-script

The server implements comprehensive type safety using:

• TypeScript for static type checking
• Zod schema validation for runtime type checking
• Proper error handling and response formatting
