• An MCP-compatible AI coding assistant (for example, Augment, Claude Code, Claude Desktop, or GitHub Copilot in VS Code 1.99+)

New Functionality

Tools

• CheckIDSConventions tool: Look up IDS conventions and best practices by using natural language queries against a curated knowledge base included with the MCP server.
• CheckTaskScriptConventions tool: Look up task script conventions and best practices by using natural language queries against a curated knowledge base included with the MCP server.
• IDSValidator tool: Validate that your IDS artifacts comply with IDS standards. Optionally checks compatibility with previously published IDS versions when configured with --config.
• GenerateElasticsearchJSON tool: Generate an elasticsearch.json file from an IDS directory for use with Elasticsearch indexing.

Prompts

• IDSResearch prompt: Research scientific instruments, software, or techniques to understand their data structures and requirements for IDS development.
• AnalyseExampleFiles prompt: Analyze example files from scientific instruments or software to understand data formats, structures, and patterns for IDS design.

Command-Line Options

• --enable-tool flag: Enable specific tools on the MCP server. This flag is mutually exclusive with the --disable-tool flag.
• --disable-tool flag: Disable specific tools on the MCP server. This removes the tool from the list of available tools in the MCP server and the MCP instructions.
