+# v0.1 Release — Design
+
+## Goal
+
+Get Distil to a clean, working v0.1 state: build passes, tests pass, docs reflect reality, MCP server implemented.
+
+## Scope
+
+### In scope
+
+- Fix broken build (kindling module type errors)
+- Commit uncommitted kindling integration work
+- Update stale APS plans to reflect actual milestone status
+- Update README and CLAUDE.md to match reality
+- Implement `@distil/mcp` package (MCP server exposing all analysis layers)
+- Add `distil mcp` CLI subcommand
+- Ensure CI passes on main
+
+### Out of scope (deferred)
+
+- npm publishing / registry setup
+- Semantic search (M5)
+- Multi-language support (M7)
+- Monorepo workspace detection
+
+## Architecture
+
+### MCP Server (`@distil/mcp`)
+
+New package at `packages/distil-mcp/`. Exposes Distil analysis via Model Context Protocol using stdio transport.
+
+**Tools:**
+
+- `distil_tree` — File tree structure
+- `distil_extract` — L1 AST extraction
+- `distil_calls` — L2 call graph
+- `distil_impact` — L2 impact analysis
+- `distil_cfg` — L3 control flow graph
+- `distil_dfg` — L4 data flow graph
+- `distil_slice` — L5 program slicing
+
+**Dependencies:** `@distil/core`, `@modelcontextprotocol/sdk`
+
+**Transport:** stdio (started via `distil mcp` or configured in editor settings)
+
+## Workstreams
+
+1. **Fix build + kindling** — Fix type errors, commit kindling module, verify build + tests
+2. **Project hygiene** — Update APS plans, README, CLAUDE.md
+3. **MCP server** — New package implementing MCP protocol
+
+Streams 2 and 3 can run in parallel after stream 1 completes.
