Developer MCP Server

A powerful context management system designed specifically for software development teams. The Developer MCP Server maintains persistent context across your coding sessions, ensuring you never lose track of your project's structure, dependencies, and progress.

Features

• Persistent Development Context: Pick up exactly where you left off in your last session, with complete context about the components, issues, and tasks you were working on.

• Session Management: Start new development sessions and record your achievements, task updates, and project status changes when you finish, creating a persistent record of your development activities.

• Dependency Tracking: Understand how components, features, and technologies relate to each other with a comprehensive dependency model.

• Project Status Insights: Get immediate visibility into project progress, including status of components, features, issues, and milestones.

• Component Context Retrieval: Understand any component's purpose, implementation details, dependencies, and related issues at a glance.

• Decision History: Track why architectural and implementation decisions were made, when, and by whom—no more guessing why something was built a certain way.

• Milestone Progress Tracking: Monitor progress toward project milestones and identify potential bottlenecks before they derail your timeline.

• Related Entity Discovery: Quickly find all related entities for any component, feature, or task to understand its complete context.

Entities

The Developer MCP Server recognizes the following types of entities in your software development context:

• Project: Overall software project or product
• Component: Module, service, package, or logical unit within a project
• Feature: Specific functionality being developed
• Issue: Bug, problem, or defect to be addressed
• Task: Work item or activity needed for development
• Developer: Team member working on the project
• Technology: Programming language, framework, library, or tool
• Decision: Important technical or architectural decision
• Milestone: Key project deadline or phase
• Environment: Development, staging, or production environment
• Documentation: Project documentation resource
• Requirement: Project requirement or specification

Relationships

The Developer MCP Server models the following relationships between entities, mirroring real-world software development dynamics:

• depends_on: Entity A requires Entity B to function
• implements: Component implements a feature
• assigned_to: Task is assigned to a developer
• blocked_by: Task is blocked by an issue
• uses: Component uses a technology
• part_of: Component is part of a project
• contains: Project contains a component
• works_on: Developer works on a project/component
• related_to: General relationship between entities
• affects: Issue affects a component
• resolves: Task resolves an issue
• created_by: Entity was created by a developer
• documented_in: Component is documented in documentation
• decided_in: Decision was made in a meeting
• required_by: Feature is required by a requirement
• has_status: Entity has a particular status
• depends_on_milestone: Task depends on reaching a milestone
• precedes: Task precedes another task (sequencing)
• reviews: Developer reviews a component
• tested_in: Component is tested in an environment

Environment Variables

The Developer MCP Server supports the following environment variables to customize where data is stored:

• MEMORY_FILE_PATH: Path where the knowledge graph data will be stored

  • Can be absolute or relative (relative paths use current working directory)
  • Default: ./developer/memory.json

• SESSIONS_FILE_PATH: Path where session data will be stored

  • Can be absolute or relative (relative paths use current working directory)
  • Default: ./developer/sessions.json

Example usage:

# Store data in the current directory
MEMORY_FILE_PATH="./dev-memory.json" SESSIONS_FILE_PATH="./dev-sessions.json" npx github:tejpalvirk/contextmanager-developer

# Store data in a specific location (absolute path)
MEMORY_FILE_PATH="/path/to/data/developer-memory.json" npx github:tejpalvirk/contextmanager-developer

# Store data in user's home directory
MEMORY_FILE_PATH="$HOME/contextmanager/developer-memory.json" npx github:tejpalvirk/contextmanager-developer

Available Tools

The Developer MCP Server provides the following tools:

• startsession: Starts a new development session and provides information about recent sessions, active projects, high-priority tasks, and upcoming milestones.

• loadcontext: Loads detailed context for an entity (project, component, feature, task, etc.) and tracks this context loading as part of the current session.

• endsession: Performs a structured analysis of the development session through multiple stages (summary, achievements, task updates, new tasks, project status) and records this information in the persistent knowledge graph.

• buildcontext: Creates new entities, relations, or observations in the knowledge graph.

• deletecontext: Removes entities, relations, or observations from the knowledge graph.

• advancedcontext: Retrieves information from the knowledge graph with different query types (graph, search, nodes, related, decisions, milestone).

Prompts

Here are some example prompts to use with the Developer MCP Server:

Starting a Session

"Start a new development session for me."

Loading Context

"Show me the current status of the AuthService project."
"Load the context for the UserProfile component."
"What are the open issues affecting the Payment feature?"
"Show me details about the upcoming Q2 Release milestone."

Recording Session Progress

"End my development session. I've been working on AuthService for 3 hours and completed user authentication flow implementation."
"Record my achievements for today: implemented password reset feature and fixed login redirect bug."
"Update the status of these tasks: Login Form is complete, User Registration is in progress."
"Create new tasks for the next sprint: Implement MFA, Add social login options."

Knowledge Graph Management

"Create a new feature called 'BillingSystem' in the ProjectX project."
"Create a relationship showing that PaymentComponent implements BillingSystem feature."
"Show me all components that depend on the DatabaseService."
"What decisions have been made about the authentication approach for ProjectX?"

Usage

The Developer MCP Server excels in scenarios like:

Context Continuity

"Let me see the component I was working on yesterday and all its dependencies."

The server retrieves your most recently accessed components along with their dependencies, issues, and related tasks, allowing you to instantly resume work without spending time reconstructing context.

Onboarding New Team Members

"Give me an overview of Project X's architecture and component structure."

New developers can quickly understand the project structure, key components, and their relationships—dramatically reducing the time needed to become productive on a new codebase.

Session Recording

"End my development session and record what I accomplished."

The server guides you through a structured process to document your achievements, task updates, and project status changes, preserving this context for future sessions and team members.

Architectural Decision Context

"Why was GraphQL chosen over REST for the API layer?"

The server retrieves the decision entity along with related meetings, developers involved, and the context in which the decision was made—preserving organizational knowledge that would otherwise be lost.

Dependency Analysis

"What would be affected if we modify the authentication service?"

Before making changes, developers can understand all components, features, and tasks that depend on a particular component, reducing the risk of unexpected breakages.

Project Progress Tracking

"What's our progress toward the Q2 release milestone?"

Project leads can instantly see the status of all tasks and features associated with a milestone, identifying at-risk items before they jeopardize the timeline.
