SigNoz

Download the pre-built binary for your platform from the GitHub Releases page, or install it via Go. The binary is a single self-contained executable with no additional runtime dependencies.

# macOS Apple Silicon
curl -L https://github.com/SigNoz/signoz-mcp-server/releases/latest/download/signoz-mcp-server_darwin_arm64.tar.gz | tar xz

# macOS Intel
curl -L https://github.com/SigNoz/signoz-mcp-server/releases/latest/download/signoz-mcp-server_darwin_amd64.tar.gz | tar xz

# Linux amd64
curl -L https://github.com/SigNoz/signoz-mcp-server/releases/latest/download/signoz-mcp-server_linux_amd64.tar.gz | tar xz

# Or via Go
go install github.com/SigNoz/signoz-mcp-server/cmd/server@latest

Log in to your SigNoz instance and navigate to Settings > API Keys. Generate a new key and copy it — this is what authenticates the MCP server to your SigNoz instance.

Move the extracted binary to a directory on your PATH or to a known absolute path, as you will reference this path in your Claude Desktop configuration.

mv signoz-mcp-server /usr/local/bin/signoz-mcp-server
chmod +x /usr/local/bin/signoz-mcp-server

Edit claude_desktop_config.json to add the SigNoz server in stdio mode. Replace the URL and API key with your actual values. For SigNoz Cloud you can also use the hosted HTTP endpoint.

Quit and relaunch Claude Desktop. Ask Claude to list available SigNoz tools or run a simple query like 'Show me all available metrics' to confirm the connection is working.
