For reference:

getMCPFeatures

• is called from the forge app as app.containers.getMCPFeatures(instance, instanceWithMCPServers.mcpServers) see code in PR 7604
• and this drivers handler forwards this to the launcher here as part of PR 571

callMCPTool

• is called from the forge app as commandMethod(instance, endpoint, ...commandData) see code in PR 7604
• and this drivers handler forwards this to the launcher here as part of PR 571

readMCPResource

• is called from the forge app as commandMethod(instance, endpoint, ...commandData) see code in PR 7604
• and this drivers handler forwards this to the launcher here as part of PR 571

Pull request overview

Adds new driver passthrough methods to support “Insights”/MCP operations by proxying requests from Forge to the launcher’s /flowforge/command endpoint.

Changes:

• Added JSDoc typedefs for MCP endpoint specification and access tokens.
• Added getMCPFeatures, callMCPTool, and readMCPResource methods that forward MCP commands to the project container’s command endpoint.
