+# MCP Server Mode (`grokkit mcp`)
+
+Grokkit can run as an **MCP (Model Context Protocol)** server, allowing AI coding agents like **Claude Code**, Cursor, or other MCP-compatible clients to call Grokkit tools directly during their workflows.
+
+## What is MCP?
+
+MCP is a protocol that lets LLMs call external tools and access resources in a standardized way. By running `grokkit mcp`, you turn Grokkit into a service that other AI tools can use.
+
+## Starting the MCP Server
+
+```bash
+grokkit mcp
+```
+
+This starts the server over **stdio** (standard input/output), which is the default transport used by Claude Code and most MCP clients.
+
+The server will run until the client disconnects.
+
+## Available Tools
+
+When running in MCP mode, the following tools are available:
+
+- **`lint_code`** — Run linter on a file and return results
+- **`analyze_code`** — Deep project analysis with educational report
+- **`generate_docs`** — Generate documentation comments for a source file
+- **`generate_tests`** — Generate unit tests for supported languages
+- **`generate_commit_msg`** — Generate conventional commit message from staged changes
+- **`run_recipe`** — Execute a named recipe from `.grokkit/recipes/`
+
+## Configuration
+
+You can control MCP behavior in your config file (`~/.config/grokkit/config.toml` or `./config.toml`):
+
+```toml
+[mcp]
+enabled = true
+tools = ["lint_code", "analyze_code", "generate_docs"]
+resources = ["recipes://local", "prompts://language"]
+```
+
+## Example Usage with Claude Code
+

+# 🔨 Workon Guide
+
+The `workon` command automates starting and completing work on todo items and fixes. It integrates with Grokkit's in-repo todo system, Git branching, and Grok AI to keep your workflow uniform and consistent.
+
+### Why use Workon?
+
+- **Automated Workflow**: Moves todo items, creates branches, generates work plans, and commits — all in one command.
+- **AI Work Plans**: Grok generates a concrete, numbered implementation plan tailored to each item.
+- **Branch Conventions**: Automatically prefixes branches with `feature/` or `fix/` for clean git history.
+- **Completion Tracking**: Moves items to completed, updates the todo index, and commits the change.
+- **Optional Integrations**: Logs work start via `cnadd` and opens your configured IDE automatically.
+
+### Usage
+
+```bash
+# Start working on a queued todo item
+grokkit workon my-todo-item
+
+# Start a fix (creates a new .md in doing/)
+grokkit workon my-bugfix -f
+
+# Custom commit message
+grokkit workon my-feature -M "feat: begin API redesign"
+
+# Complete a todo item (move to completed/, update index)
+grokkit workon my-todo-item -c
+
+# Complete a fix (move to completed/, no index update)
+grokkit workon my-bugfix -c -f
+```
+
+### Options
+
+| Flag      | Short | Description                                         | Default                                  |
+|-----------|-------|-----------------------------------------------------|------------------------------------------|
+| --message | -M    | Custom commit message                               | "Start working on \<todo_item_title\>"   |
+| --fix     | -f    | Treat as fix instead of todo                        | false                                    |
+| --complete| -c    | Complete the item (cannot be combined with -M)      | false                                    |
+
+### How It Works
+
+#### Starting Work (default)
+
+1. **Bootstraps todo structure** — Creates `todo/queued/`, `todo/doing/`, and `todo/completed/` directories if they don't exist.
+2. **Moves or creates the item**:
+   - **Todo mode** (default): Moves `todo/queued/<title>.md` to `todo/doing/<title>.md`.
+   - **Fix mode** (`-f`): Creates a new `todo/doing/<title>.md` with a skeleton `## Work Plan` heading.
+3. **Creates a git branch** — `feature/<title>` for todos, `fix/<title>` for fixes. If the branch already exists, checks it out instead.
+4. **Generates a Work Plan** — Sends the item content to Grok and appends a numbered implementation plan to the markdown file.
+5. **Commits** — Stages the `todo/` directory and commits with the default or custom message.
+6. **Optional post-steps** (graceful fallbacks if unavailable):
+   - Logs the start of work via `cnadd` (if installed).
+   - Opens the repository in your configured IDE.
+
+#### Completing Work (`-c`)
+
+1. Moves `todo/doing/<title>.md` to `todo/completed/<title>.md`.
+2. For non-fix items: updates `todo/README.md` — removes the entry from `## Queued` and appends it to `## Completed`.
+3. Commits the change with the message `Complete work on <title>`.
+
+### Todo Folder Structure
+
+Workon assumes and maintains this in-repo ticketing layout:
+
+```
+todo/
+  README.md        # Index of all items (Queued / Completed sections)
+  queued/           # Items waiting to be worked on
+    my-feature.md
+    another-item.md
+  doing/            # Items currently in progress
+    active-item.md
+  completed/        # Finished items
+    done-item.md
+```
+
+If the `todo/` folder doesn't exist, `workon` creates it automatically.
+
+### Configuration
+
+The workon command respects two config keys in `~/.config/grokkit/config.toml`:
+
+```toml
+[commands]
+  workon.model = "grok-4-1-fast-non-reasoning"  # Model for work plan generation
+  workon.ide = "code"                            # IDE command to open repo (e.g. "code", "goland", "nvim")
+```
+
+If `workon.ide` is empty or unset, the IDE step is silently skipped. If `cnadd` is not installed, logging is silently skipped.
+
+### Title Handling
+
+- Spaces in the title are automatically replaced with dashes.
+- The title is used as both the markdown filename (without prefix) and the branch name (with `feature/` or `fix/` prefix).
+
+### Examples
+
+```bash
+# Full workflow: queue an item, work on it, complete it
+echo "# Add caching" > todo/queued/add-caching.md
+grokkit workon add-caching
+# ... do the work ...
+grokkit workon add-caching -c
+
+# Quick fix workflow
+grokkit workon fix-null-pointer -f
+# ... fix the bug ...
+grokkit workon fix-null-pointer -c -f
+```

+# MCP Server Feature
+
+**Description**: Add an MCP (Model Context Protocol) server mode to grokkit, exposing its capabilities as tools and resources for Claude Code and other MCP-compatible clients.
+
+## Problem It Solves
+
+Grokkit's AI-powered code operations (linting, docs, test generation, analysis) are locked behind the CLI. MCP integration lets external AI clients invoke them programmatically, composing grokkit's strengths with broader workflows.
+
+## Benefits
+
+- **Composability**: Claude Code (or any MCP client) can call grokkit tools mid-conversation.
+- **No core changes**: New `grokkit mcp` command wraps existing functionality via interfaces.
+- **Stdio transport**: No HTTP server to manage — Claude Code pipes stdio directly.
+- **Recipes as resources**: MCP clients can browse and invoke workflow recipes.
+- **Leverages existing architecture**: `AIClient` and `GitRunner` interfaces already support dependency injection.
+
+## Architecture Notes
+
+Grokkit is well-suited for this:
+
+- **Interface-based design**: `AIClient` and `GitRunner` are already abstractions — inject real implementations into MCP tool handlers.
+- **Clean package separation**: Each internal package (grok, git, linter, recipe, prompts) maps naturally to an MCP tool.
+- **Cobra command tree**: Adding `cmd/mcp.go` is trivial.
+- **Streaming caveat**: MCP tools return complete results, so use `StreamSilent` (captures without printing) rather than `Stream`.
+- **File-writing tools** (`edit`, `workon`): Need careful scoping so the MCP client understands what changed.
+
+## High-Level Implementation
+
+### Phase 1: Foundation
+
+1. **Add MCP Go SDK** (e.g., `github.com/mark3labs/mcp-go`) to `go.mod`.
+2. **Create `internal/mcp/server.go`** — MCP server that registers tools and resources.
+3. **Create `cmd/mcp.go`** — `grokkit mcp` command that starts the stdio server.
+
+### Phase 2: Tools
+
+Wrap existing functionality as MCP tools. Priority order:
+
+| Tool | Wraps | Notes |
+|------|-------|-------|
+| `lint_code` | `internal/linter` | Stateless. File path in, results out. |
+| `generate_commit_msg` | `cmd/commit.go` logic | Reads git diff, calls Grok, returns message. |
+| `analyze_code` | `cmd/analyze.go` + `internal/prompts` | File in, analysis out. |
+| `generate_docs` | `cmd/docs.go` | File in, docs out (9 styles available). |
+| `generate_tests` | `cmd/testgen.go` | File in, tests out. |
+| `run_recipe` | `internal/recipe` | Recipe name + params in, results out. |
+
+Each tool handler:
+- Extracts core logic from the Cobra `RunE` function into a reusable function.
+- Injects real `AIClient` and `GitRunner` implementations.
+- Returns complete text results (no streaming to client).
+
+### Phase 3: Resources
+
+| Resource | Source | Description |
+|----------|--------|-------------|
+| `recipes://local` | `.grokkit/recipes/` | Project-local workflow recipes |
+| `recipes://global` | `~/.local/share/grokkit/recipes/` | Global recipes |
+| `prompts://language` | `.grokkit/prompts/` | Language-specific analysis prompts |
+
+## Flags / Config
+
+| Key | Description |
+|-----|-------------|
+| `mcp.enabled` | Enable MCP server mode |
+| `mcp.tools` | List of tools to expose (default: all) |
+| `mcp.resources` | List of resources to expose (default: all) |
+
+## Implementation Notes
+
+- **Entry point**: `grokkit mcp` starts stdio server, blocks until EOF.
+- **No breaking changes**: Entirely additive — new command, new package.
+- **Testing**: Mock `AIClient` and `GitRunner` interfaces; table-driven tests per tool.
+- **Effort**: Medium (~300-500 LOC). SDK does the protocol heavy lifting.
+- **Prereqs**: Choose and evaluate a Go MCP SDK.
+
+## ROI
+
+**High**. Turns grokkit from a standalone CLI into a composable service:
+
+| Capability | Standalone | With MCP |
+|------------|-----------|----------|
+| Lint | `grokkit lint` | Claude calls it mid-review |
+| Docs | `grokkit docs` | Claude generates docs in context |
+| Tests | `grokkit testgen` | Claude generates + validates tests |
+| Recipes | `grokkit recipe` | Claude orchestrates multi-step workflows |
+| Analysis | `grokkit analyze` | Claude gets language-aware code analysis |
+## Work Plan
+
+1. **Evaluate and add MCP SDK**  
+   - Research Go MCP SDKs (`github.com/mark3labs/mcp-go` or equivalent).  
+   - Add to `go.mod`, run `go mod tidy`.  
+   - Commit: `feat(mcp): add MCP SDK dependency`.
+
+2. **Implement MCP server foundation** (`internal/mcp`)  
+   - Create `internal/mcp/server.go`: Initialize stdio server, register tools/resources.  
+   - Inject real `AIClient` and `GitRunner` impls.  
+   - Use `StreamSilent` for non-streaming results.  
+   - Commit: `feat(mcp): add MCP server foundation`.
+
+3. **Add `cmd/mcp.go`**  
+   - Cobra command `grokkit mcp` to start stdio server.  
+   - Add config flags: `--tools`, `--resources` (comma-separated).  
+   - Blocks until EOF.  
+   - Test: Manual `grokkit mcp` + simple MCP client.  
+   - Commit: `feat(mcp): add grokkit mcp CLI command`.
+
+4. **Extract reusable functions from existing commands**  
+   - `lint_code`: Extract from `cmd/lint.go` → `internal/linter.RunLint(path) string`.  
+   - `generate_commit_msg`: Extract from `cmd/commit.go` → `internal/git.GenerateCommitMsg() string`.  
+   - Commit per extraction: `refactor(lint): extract reusable lint function`.
+
+5. **Implement Phase 2 tools** (priority order, 1 commit per 2 tools)  
+   - Register each as MCP tool in `server.go`.  
+   - `lint_code`, `analyze_code`.  
+   - `generate_docs`, `generate_tests`.  
+   - `generate_commit_msg`, `run_recipe`.

+# `grokkit workon`
+
+**Description**: Automates the initiation of new todo item and fix development. 
+
+1. selects a todo item out of the todo queue and moves it to the "doing" folder; 
+2. creates a branch based on the item; 
+3. generates a plan for implementation (amending it to the todo item under the heading "Work Plan");
+4. commits the plan to the branch.
+5. [optional] logs the beginning of the work using `cnadd` (if available).
+6. [optional] opens the branch in the IDE (specified in the config).
+
+**Assumptions**:
+
+Grokkit is being customized to suit my own development workflow. So, there are a number of features that may not be translatable to other developers' habits. As such, this feature assumes that the repository has a "todo" folder with a "queued", "doing" and "completed" subfolder, that function as the in-situ ticketing system. If the "todo" folder is not present, grokkit will create it.
+
+Also, if no IDE is specified in the config, the `workon` command will default to not opening the editor. If `cnadd` is not available, the `workon` command will default to not logging the beginning of the work.
+
+**Benefits**:
+
+1. Boosts productivity by automating routine tasks.
+2. Makes it easier to track the progress of the work.
+3. Makes feature development more uniform and consistent.
+
+**Usage**:
+```
+grokkit workon <todo_item_title> [[-m '<custom_commit_message>'] [-f]] | [-c]
+```
+
+**Arguments**:
+- `<todo_item_title>`: The item to be worked on. 
+  - If this is a todo, then there should be a Markdown entry in the queued folder with the same name, which will be moved to the doing folder. That should also be the name of the branch. 
+  - If this is a fix, then use the argument as a branch name and as the name of a markdown file to be created, where the Work Plan will be stored in the "doing" folder. 
+  - In both instances, If spaces are present, replace them with dashes.
+
+- `-m '<custom_commit_message>'`: custom commit message to use for the branch. Default is "Start working on <todo_item_title>".
+
+- `-f`: This signifies a "fix" rather than a todo item (the default is always a todo item)
+
+- `-c`: "completes" the work item (note: cannot be used with other flags). This means: 
+  - If it is a todo, it will be moved to the "completed" folder, and the index readme will be updated. 
+  - If it is a fix, the work plan will be moved to the "completed folder". No index update is necessary. 
+  - In either case, the update will be committed to the branch.
