 ## Project Purpose
 
-UnrealDocGenerator is a tool for generating documentation from Unreal Engine C++ header files. The `samples/` directory contains representative Unreal Engine headers used as test inputs:
-
-- `samples/GeomUtils.h` — Small utility header (~6 KB): geometry/math helpers in `UE::AI` namespace
-- `samples/AIController.h` — Medium header (~22 KB): `AAIController` class with movement, behavior tree, perception, and blackboard integration
-- `samples/GameplayTagsManager.h` — Large/complex header (~43 KB): `UGameplayTagsManager` singleton with tag trees, INI/DataTable loading, and editor support
-
-These samples cover a range of complexity (free functions, large classes, deeply nested types, macros, delegates) suitable for stress-testing a parser or doc generator.
+UnrealDocGenerator is a tool for generating documentation from Unreal Engine C++ header files and exposing it to Claude via an MCP server for item-granularity lookups.
 
 ## Current State
 
-Implementation complete. Three Python files + a Claude Code skill:
+Implementation complete. Four Python files + MCP registration:
 - `ue_parser.py` — Parses UE headers into dataclasses
 - `ue_markdown.py` — Renders parsed data as Markdown (ultra-compact format, documented items only)
 - `generate.py` — CLI entry point; two-pass pipeline (parse-all → build type index → render-all)
-- `.claude/skills/ue-api/SKILL.md` — Claude Code skill; queries docs via `$UE_DOCS_PATH`, falls back to `$UE_ENGINE_ROOT` source headers
+- `ue_mcp_server.py` — MCP server exposing 5 tools for item-granularity doc lookups
+- `.mcp.json` — Registers the MCP server with Claude Code (stdio transport)
 
 ## Usage
 
 ```bash
-python generate.py samples/ docs/          # process directory → docs/
-python generate.py samples/AIController.h docs/   # single file
+python generate.py <input> [input2 ...] <output_dir>
+
+python generate.py Runtime/Engine/ Runtime/AIModule/ docs/   # multiple directories
+python generate.py Runtime/Engine/Classes/GameFramework/Actor.h docs/  # single file
 ```
 
 Output: one `.md` per `.h` + `docs/type-index.txt` (compact `TypeName: path/to/File.md` lookup).
 
-Agent lookup pattern: `grep "^AController:" docs/type-index.txt` → instant single-line result.
+The last argument is always the output directory. All preceding arguments are inputs (files or directories, processed recursively).
+
+## MCP Server
+
+`ue_mcp_server.py` exposes 5 tools Claude can call directly:
+
+| Tool | Purpose |
+|---|---|
+| `search_types(pattern)` | Regex search over `type-index.txt` — locate a type before fetching details |
+| `get_class_overview(class_name)` | Compact view: description + inherits + property/function name lists |
+| `get_member(class_name, member_name)` | Full doc for one function or property (all overloads) |
+| `get_file(relative_path)` | Full `.md` file — use when you need delegates, enums, or multiple classes |
+| `search_source(pattern, path_hint)` | Grep UE source `.h` files via `$UE_ENGINE_ROOT` |
+
+Requires `pip install mcp`. Reads `$UE_DOCS_PATH`; `search_source` also requires `$UE_ENGINE_ROOT`.
+
+Typical query flow: `search_types` → `get_class_overview` → `get_member` (~3 calls, ~15 lines vs ~100 lines for a full file read).

 - `find_matching_close()` extracts balanced `{}`/`()` while skipping `//`, `/* */`, and string literals.
 - Only items with actual C++ doc comments (`/** */`) are included in output (`_has_doc()` filter).
 - Two-pass pipeline in `generate.py`: Pass 1 parses all files, Pass 2 renders with cross-reference links.
+- Multi-input: each `(header, base)` pair tracks its own base dir for correct relative output paths.
 - Inline cross-references: base class names linked to their `.md` when in corpus (`_make_type_link()`).
-- No "See also" section — inline links in `*Inherits*:` lines cover cross-file navigation.
 - Deprecated functions excluded from output (`not f.is_deprecated` in visibility filter).
 - Enums with no value descriptions use compact inline format (`Values: A, B, C`) instead of a table.
 - Placeholder descriptions (`------//`) filtered by `_PLACEHOLDER_RE` in `_fn_body()`.
 
 ## Critical Gotchas
 
-- **Never** use `\s` inside a `[...]` character class with `*?` on C++ source — causes catastrophic regex backtracking (hangs on `AIController.h`). Use line-based scanning instead.
+- **Never** use `\s` inside a `[...]` character class with `*?` on C++ source — causes catastrophic regex backtracking. Use line-based scanning instead.
 - Identifier regex must be `r'\w+'`, **not** `r'[\w:~]+'` — the latter consumes `public:` as one token, breaking access specifier detection (all members become `private`).
 - Module name casing: use `_caps_to_camel()` (not `.title()`) — `AIMODULE.title()` → `Aimodule` instead of `AIModule`.
