Seq MCP: Datalust Seq logs and SQL for IntelliJ IDEA and JetBrains IDEs

Search Datalust Seq logs from your IDE. Seq MCP is an IntelliJ IDEA plugin for structured log search, SQL queries and AI-assisted debugging in compatible JetBrains IDEs. It exposes 18 tools through the IDE's bundled Model Context Protocol (MCP) server, so a connected AI assistant can investigate application events alongside your project.

Features

• Search structured log events by filter and time range, convert fuzzy text to strict filters, and wait for new matching events.
• Run Seq SQL queries and return structured JSON rows or CSV results.
• Inspect saved SQL queries, signals, workspaces and dashboards.
• Check server capabilities and credential permissions, and create event permalinks when supported by the server and credentials.
• Store default API keys and workspace credential overrides in JetBrains Password Safe.

Requirements

• IntelliJ IDEA or a compatible JetBrains IDE with the bundled MCP Server plugin (com.intellij.mcpServer). The declared minimum IntelliJ Platform build is 263 (2026.3), with no upper bound. The build and Plugin Verifier target IntelliJ IDEA Ultimate 263.7307.200; this does not establish compatibility with every other IDE or later build.
• A reachable Datalust Seq server containing the logs you want to investigate. Use an API key with permission to read the required data when the server requires authentication; anonymous access depends on server configuration. Available operations depend on server capabilities and credential permissions.
• An MCP-compatible AI assistant connected to the IDE's bundled MCP server. This plugin extends that server; it does not run a standalone MCP server or install Seq.

Installation and setup

1. Install Seq MCP from JetBrains Marketplace in a compatible IDE.
2. Enable the IDE's bundled MCP server and connect your assistant using the JetBrains MCP server setup guide.
3. Ask your assistant to call SeqEnableIntegration for the project you want to investigate, or open Settings | Tools | Seq MCP and check Enable for this project.
4. Ask your assistant to call SeqConfigureConnection with the server URL and credentials, or enter them in the SEQ_SERVER_URL, SEQ_API_KEY and workspace-specific key fields in IDE settings and apply. These fields are plugin settings, not required environment variables.
5. Wait for project indexing to finish, then ask your connected assistant to search recent errors or run a Seq SQL query.

See the MCP tools, query examples and troubleshooting. Visit the project repository or report an issue with your IDE build, plugin version and failing tool name, omitting API keys and private log data.

Development
