GreatScottyMac/context-portal: Context Portal (ConPort): A memory bank MCP server building a project-specific knowledge graph to supercharge AI assistants. Enables powerful Retrieval Augmented Generation (RAG) for context-aware development in your IDE.

A database-backed Model Context Protocol (MCP) server for managing structured project context, designed to be used by AI assistants and developer tools within IDEs and other interfaces.

Context Portal (ConPort) is your project's memory bank. It's a tool that helps AI assistants understand your specific software project better by storing important information like decisions, tasks, and architectural patterns in a structured way. Think of it as building a project-specific knowledge base that the AI can easily access and use to give you more accurate and helpful responses.

What it does:

• Keeps track of project decisions, progress, and system designs.
• Stores custom project data (like glossaries or specs).
• Helps AI find relevant project information quickly (like a smart search).
• Enables AI to use project context for better responses (RAG).
• More efficient for managing, searching, and updating context compared to simple text file-based memory banks.

ConPort provides a robust and structured way for AI assistants to store, retrieve, and manage various types of project context. It effectively builds a project-specific knowledge graph, capturing entities like decisions, progress, and architecture, along with their relationships. This structured knowledge base, enhanced by vector embeddings for semantic search, then serves as a powerful backend for Retrieval Augmented Generation (RAG), enabling AI assistants to access precise, up-to-date information for more context-aware and accurate responses.

It replaces older file-based context management systems by offering a more reliable and queryable database backend (SQLite per workspace). ConPort is designed to be a generic context backend, compatible with various IDEs and client interfaces that support MCP.

Key features include:

• Structured context storage using SQLite (one DB per workspace, automatically created).
• MCP server (context_portal_mcp) built with Python/FastAPI.
• A comprehensive suite of defined MCP tools for interaction (see "Available ConPort Tools" below).
• Multi-workspace support via workspace_id.
• Primary deployment mode: STDIO for tight IDE integration.
• Enables building a dynamic project knowledge graph with explicit relationships between context items.
• Includes vector data storage and semantic search capabilities to power advanced RAG.
• Serves as an ideal backend for Retrieval Augmented Generation (RAG), providing AI with precise, queryable project memory.
• Provides structured context that AI assistants can leverage for prompt caching with compatible LLM providers.
• Manages database schema evolution using Alembic migrations, ensuring seamless updates and data integrity.

Before you begin, ensure you have the following installed:

• Python: Version 3.8 or higher is recommended.
  • Download Python
  • Ensure Python is added to your system's PATH during installation (especially on Windows).
• uv: (Highly Recommended) A fast Python environment and package manager. Using uv significantly simplifies virtual environment creation and dependency installation.
  • Install uv

The recommended way to install and run ConPort is by using uvx to execute the package directly from PyPI. This method avoids the need to manually create and manage virtual environments.

In your MCP client settings (e.g., mcp_settings.json), use the following configuration:

{
  "mcpServers": {
    "conport": {
      "command": "uvx",
      "args": [
        "--from",
        "context-portal-mcp",
        "conport-mcp",
        "--mode",
        "stdio",
        "--workspace_id",
        "${workspaceFolder}",
        "--log-file",
        "./logs/conport.log",
        "--log-level",
        "INFO"
      ]
    }
  }
}

• command: uvx handles the environment for you.
• args: Contains the arguments to run the ConPort server.
• ${workspaceFolder}: This IDE variable is used to automatically provide the absolute path of the current project workspace.
• --log-file: Optional: Path to a file where server logs will be written. If not provided, logs are directed to stderr (console). Useful for persistent logging and debugging server behavior.
• --log-level: Optional: Sets the minimum logging level for the server. Valid choices are DEBUG, INFO, WARNING, ERROR, CRITICAL. Defaults to INFO. Set to DEBUG for verbose output during development or troubleshooting.

These instructions guide you through setting up ConPort for development or contribution by cloning its Git repository and installing dependencies.

1. Clone the Repository: Open your terminal or command prompt and run:

   git clone https://github.com/GreatScottyMac/context-portal.git
   cd context-portal

2. Create and Activate a Virtual Environment: In the context-portal directory:

   Activate the environment:

   • Linux/macOS (bash/zsh):

     source .venv/bin/activate

   • Windows (Command Prompt):

     .venv\Scripts\activate.bat

   • Windows (PowerShell):

     .venv\Scripts\Activate.ps1

3. Install Dependencies: With your virtual environment activated:

   uv pip install -r requirements.txt

4. Verify Installation (Optional): Ensure your virtual environment is activated.

   uv run python src/context_portal_mcp/main.py --help

   This should output the command-line help for the ConPort server.

Purpose of the --workspace_id Command-Line Argument:

When you launch the ConPort server, particularly in STDIO mode (--mode stdio), the --workspace_id argument serves several key purposes:

1. Initial Server Context: It provides the server process with the absolute path to the project workspace it should initially be associated with.
2. Critical Safety Check: In STDIO mode, this path is used to perform a vital check that prevents the server from mistakenly creating its database files (context.db, conport_vector_data/) inside its own installation directory. This protects against misconfigurations where the client might not correctly provide the workspace path.
3. Client Launch Signal: It's the standard way for an MCP client (like an IDE extension) to signal to the server which project it is launching for.

Important Note: The --workspace_id provided at server startup is not automatically used as the workspace_id parameter for every subsequent MCP tool call. ConPort tools are designed to require the workspace_id parameter explicitly in each call (e.g., get_product_context({"workspace_id": "..."})). This design supports the possibility of a single server instance managing multiple workspaces and ensures clarity for each operation. Your client IDE/MCP client is responsible for providing the correct workspace_id with each tool call.

Key Takeaway: ConPort critically relies on an accurate --workspace_id to identify the target project. Ensure this argument correctly resolves to the absolute path of your project workspace, either through IDE variables like ${workspaceFolder} or by providing a direct absolute path.

ConPort's effectiveness with LLM agents is significantly enhanced by providing specific custom instructions or system prompts to the LLM. This repository includes tailored strategy files for different environments:

• For Roo Code:

  • roo_code_conport_strategy: Contains detailed instructions for LLMs operating within the Roo Code VS Code extension, guiding them on how to use ConPort tools for context management.
  
  

• For CLine:

  • cline_conport_strategy: Contains detailed instructions for LLMs operating within the Cline VS Code extension, guiding them on how to use ConPort tools for context management.
  
  

• For Windsurf Cascade:

  • cascade_conport_strategy: Specific guidance for LLMs integrated with the Windsurf Cascade environment. Important: When initiating a session in Cascade, it is necessary to explicity tell the LLM:

  Initialize according to custom instructions
  

• For General/Platform-Agnostic Use:

  • generic_conport_strategy: Provides a platform-agnostic set of instructions for any MCP-capable LLM. It emphasizes using ConPort's get_conport_schema operation to dynamically discover the exact ConPort tool names and their parameters, guiding the LLM on when and why to perform conceptual interactions (like logging a decision or updating product context) rather than hardcoding specific tool invocation details.
  
  

How to Use These Strategy Files:

1. Identify the strategy file relevant to your LLM agent's environment.
2. Copy the entire content of that file.
3. Paste it into your LLM's custom instructions or system prompt area. The method varies by LLM platform (IDE extension settings, web UI, API configuration).

These instructions equip the LLM with the knowledge to:

• Initialize and load context from ConPort.
• Update ConPort with new information (decisions, progress, etc.).
• Manage custom data and relationships.
• Understand the importance of workspace_id. Important Tip for Starting Sessions: To ensure the LLM agent correctly initializes and loads context, especially in interfaces that might not always strictly adhere to custom instructions on the first message, it's a good practice to start your interaction with a clear directive like: Initialize according to custom instructions. This can help prompt the agent to perform its ConPort initialization sequence as defined in its strategy file.

When you first start using ConPort in a new or existing project workspace, the ConPort database (context_portal/context.db) will be automatically created by the server if it doesn't exist. To help bootstrap the initial project context, especially the Product Context, consider the following:

1. Create projectBrief.md: In the root directory of your project workspace, create a file named projectBrief.md.
2. Add Content: Populate this file with a high-level overview of your project. This could include:
   • The main goal or purpose of the project.
   • Key features or components.
   • Target audience or users.
   • Overall architectural style or key technologies (if known).
   • Any other foundational information that defines the project.
3. Automatic Prompt for Import: When an LLM agent using one of the provided ConPort custom instruction sets (e.g., roo_code_conport_strategy) initializes in the workspace, it is designed to:
   • Check for the existence of projectBrief.md.
   • If found, it will read the file and ask you if you'd like to import its content into the ConPort Product Context.
   • If you agree, the content will be added to ConPort, providing an immediate baseline for the project's Product Context.

If projectBrief.md is not found, or if you choose not to import it:

• The LLM agent (guided by its custom instructions) will typically inform you that the ConPort Product Context appears uninitialized.
• It may offer to help you define the Product Context manually, potentially by listing other files in your workspace to gather relevant information.

By providing initial context, either through projectBrief.md or manual entry, you enable ConPort and the connected LLM agent to have a better foundational understanding of your project from the start.

The ConPort server exposes the following tools via MCP, allowing interaction with the underlying project knowledge graph. This includes tools for semantic search powered by vector data storage.
