# MCP Toolchain Manager ## Purpose Detect, explain, validate, and record tool capabilities needed by WebDev Agent Kit skills without turning tool setup into automatic or unsafe behavior. This skill exists to keep MCP usage deliberate. It identifies which capabilities are required for the current workflow, which providers are already available, which providers are missing, what each missing capability blocks, which fallback is allowed, and what official source must be verified before installation or configuration is proposed. ## When To Use Use this skill when: - a selected skill declares capability dependencies in `tool-capabilities-manifest.json`; - a task requires rendered UI verification, official documentation lookup, project context retrieval, visual references, GitHub metadata, or another external capability; - the agent needs to audit available vs missing MCP servers, native tools, connectors, or fallbacks; - the user asks what MCP servers or tools are required for the skill pack; - the user asks to install, configure, validate, or troubleshoot MCP tools; - `project/mcp-profile.md` must be created or refreshed; - a missing tool limitation must be reported before fallback behavior. Use this skill in `Standard Workflow` or `Deep Workflow` when tool capability affects the current slice. It may also be used in `Lightweight Workflow` only when the user directly asks about MCP/tool availability or when a missing already-required capability prevents a narrow task from...
