v2.2.0 — MCP Tools: Fetch, Memory, Filesystem

What's New

Three new built-in MCP tools, configured during relay onboard:

Fetch MCP

• Read any web page as clean markdown
• The AI can fetch documentation, articles, API responses, and changelogs
• Requires uvx (Python package runner) — the wizard checks and offers to install it

Memory MCP

• Persistent knowledge graph across conversations
• The AI remembers your preferences, project facts, decisions, and conventions
• Stored in ~/.relay/memory.jsonl (respects --dev mode)

Filesystem MCP

• Read and write files outside the current project directory
• Restricted to user-configured directories for safety
• Useful for cross-project operations, reading logs, writing output files

Onboarding Improvements

• OpenCode detection — Step 1 now checks if OpenCode is installed and offers npm i -g opencode-ai@latest
• Reorganized wizard — 5 clear steps: OpenCode → Bot Token → User ID → MCP Tools → Voice
• Dependency checks — warns about missing uvx for Fetch MCP with install option
• Cross-platform — works on Linux, macOS, and Windows

Other Changes

• /mcp command now shows numbered servers with action buttons
• Updated all documentation (README, CLAUDE.md, docs/)
