Tools

Codeine provides MCP tools for code reasoning and analysis.

Thinking & Reasoning

Tool	Description
`thinking`	Record reasoning steps, analysis, decisions
`session`	Manage reasoning sessions (start, context, end)
`items`	Query and manage thoughts, requirements, tasks
`project`	Project analytics (health, critical path, impact)

thinking

Record structured reasoning steps with thought chains.

await thinking({
  thought: "Analyzing the authentication module",
  thought_number: 1,
  total_thoughts: 3,
  thought_type: "analysis"
})

session

Manage reasoning sessions with persistence.

// Start a new session
await session({ action: "start", goal: "Refactor auth module" })

// Get current context
await session({ action: "context" })

// End session
await session({ action: "end" })

Code Analysis

Tool	Description
`code_inspection`	Python code analysis (26 actions)
`recommender`	Refactoring and test coverage recommendations
`diagram`	Generate UML diagrams (class, sequence, etc.)

code_inspection

Analyze code structure with 26 available actions:

list_modules - List all modules
list_classes - List all classes
describe_class - Get detailed class info
get_class_hierarchy - Inheritance hierarchy
find_usages - Find where code is used
find_callers - Find all callers
find_callees - Find all callees
analyze_dependencies - Module dependencies
get_complexity - Complexity metrics
get_architecture - Architecture overview

await code_inspection({
  action: "list_classes"
})

await code_inspection({
  action: "describe_class",
  target: "MyClass"
})

recommender

Get refactoring and test coverage recommendations.

await recommender({
  recommender_type: "refactoring"
})

await recommender({
  recommender_type: "test_coverage"
})

diagram

Generate UML diagrams in Mermaid format.

Diagram types:

class_hierarchy - Inheritance tree
class_diagram - Class with methods
sequence - Method call sequence
dependencies - Module dependencies

await diagram({
  diagram_type: "class_hierarchy",
  target: "BaseClass"
})

Instance Management

Tool	Description
`instance_manager`	Manage RETER instances and sources

instance_manager

Manage multiple RETER instances for different projects.

await instance_manager({
  action: "list"
})
