SpaceBridge-MCP is a server designed for seamless integration of AI tools with the SpaceBridge platform, improving issue management in software development environments. It offers tools to automate and manage issues across multiple platforms, reducing context switching and enhancing AI capabilities.

SpaceBridge-MCP

A Model Context Protocol (MCP) server that integrates with the SpaceBridge REST API (https://spacebridge.io/docs) to automate issue management across connected issue trackers.

SpaceBridge-MCP Overview

Overview

SpaceBridge-MCP is a Model Context Protocol (MCP) server designed to integrate AI development tools (like Claude code, Windsurf, Cursor) with the SpaceBridge issue aggregation platform. It allows developers to interact with their issue trackers directly from their coding environment via their AI assistant.

Core Benefits:

  • Reduced Context Switching: Manage issues (search, create, view) without leaving the development environment.
  • Automated Issue Tracking: Facilitates workflows where AI assistants can automatically find or create relevant issues associated with code changes (e.g., for commit messages).
  • Enhanced AI Context: Provides AI assistants with access to issue details (via get_issue_by_id), enabling more context-aware code generation and analysis.
  • Centralized Interaction: Leverages SpaceBridge to interact with multiple underlying issue trackers (Jira, GitHub Issues, etc.) through a single interface.

Functionality:

The server exposes MCP tools and resources that translate natural language requests from an AI assistant into SpaceBridge API calls. Key features include intelligent duplicate checking (using similarity search and LLM comparison) before issue creation and flexible handling of organization/project context.

Features

  • Resource: get_issue_by_id: Retrieves details for a specific issue using its SpaceBridge ID.
  • Tool: search_issues: Searches for issues based on a query string using either full-text or similarity search.
  • Tool: create_issue: Creates a new issue. Before creation, it performs a similarity search for potentially duplicate issues and uses an LLM to compare the top results against the new issue's content. If a likely duplicate is found, it returns the existing issue's ID; otherwise, it creates the new issue.
  • Tool: update_issue: Updates an existing issue.

Getting Started

Prerequisites

  • Python 3.9+
  • pip (Python package installer)
  • Access to a SpaceBridge instance and API key.
  • OpenAI API Key (for the create_issue tool's duplicate check).

Installation using pip

  1. Install the package: 
    pip install spacebridge-mcp

Installation from source

  1. Clone the repository: 
    git clone <repository-url>
cd spacebridge-mcp
  2. Create and activate a virtual environment (recommended): 
    # Use .venv as requested by user
python -m venv .venv
source .venv/bin/activate  # On Windows use `.venv\Scripts\activate`
  3. Install the package in editable mode, including development dependencies (for testing): 
    # Use the specific python from your virtual env if 'pip' isn't found directly
.venv/bin/python -m pip install -e ".[dev]"
# Or if 'pip' is correctly on PATH for the venv:
# pip install -e ".[dev]"
    Note: This installs the package such that changes to the source code are immediately reflected without reinstalling. Including [dev] installs packages needed for running tests, like pytest and respx.

Configuration

The server requires the following configuration values:

  • Required:
    • SPACEBRIDGE_API_KEY: Your API key for authenticating with SpaceBridge.
  • Optional (Configuration & Context):
    • SPACEBRIDGE_ORG_NAME: Explicitly sets the organization context. (Optional).
    • SPACEBRIDGE_PROJECT_NAME: Explicitly sets the project context. (Optional).
  • Optional (Duplicate Detection Behavior):
    • OPENAI_API_KEY: Your OpenAI API key. Required if you want to use OpenAI for duplicate checking. If not provided, the server falls back to threshold-based checking.
    • DUPLICATE_SIMILARITY_THRESHOLD: Sets the similarity score threshold (0.0 to 1.0) used for duplicate detection when OPENAI_API_KEY is not provided. (Default: 0.75).
    • OPENAI_API_BASE: Specifies a custom base URL for the OpenAI API (e.g., for local models or other providers). (Used only if OPENAI_API_KEY is set).
    • OPENAI_MODEL: Specifies the OpenAI model name to use for duplicate checks. (Default: gpt-4o). (Used only if OPENAI_API_KEY is set).

These values, along with organization/project context, can be provided in multiple ways. The server determines the final values based on the following order of precedence (highest first):

  1. Command-line Arguments: Pass arguments when running the server. These override all other methods.

    spacebridge-mcp-server \
  --spacebridge-api-key "YOUR_SB_KEY" \
  --openai-api-key "YOUR_OPENAI_KEY" \
  --org-name "YOUR_ORG" \        # Explicit Org Name
  --project-name "YOUR_PROJECT"  # Explicit Project Name
  # --project-dir "/path/to/your/project" # Optional: Specify dir for Git detection

    (Use spacebridge-mcp-server --help to see all available arguments.)

  2. Environment Variables: Set standard environment variables. These override .env files and Git detection.

    # Example setting required and some optional vars
export SPACEBRIDGE_API_KEY="YOUR_SB_KEY"
export OPENAI_API_KEY="YOUR_OPENAI_KEY" # If using OpenAI duplicate check
export SPACEBRIDGE_ORG_NAME="YOUR_ORG"
export SPACEBRIDGE_PROJECT_NAME="YOUR_PROJECT"
# Then run:
spacebridge-mcp-server

  3. .env File: Create a file named .env in the directory where you run the server. Environment variables and command-line arguments override values in this file.

    # .env file content
SPACEBRIDGE_API_KEY="YOUR_SB_KEY"
OPENAI_API_KEY="YOUR_OPENAI_KEY"
SPACEBRIDGE_ORG_NAME="YOUR_ORG"
SPACEBRIDGE_PROJECT_NAME="YOUR_PROJECT"

    The server automatically loads values from this file if it exists.

  4. Git Configuration Detection: If organization and project are not set via arguments or environment variables, the server attempts to detect them from the .git/config file.

    • It first checks in the directory specified by the --project-dir argument (if provided).
    • If --project-dir is not used, it checks the current working directory where the server was started.

Context Handling Priority:

The organization and project context used for API calls is determined as follows:

  1. Startup Context: The context determined during server startup (using the precedence above: Args > Env Vars > Git Detection) is used by default.
  2. Tool Parameter Fallback: If (and only if) the server could not determine the context during startup (e.g., no explicit config provided and not running in a Git repository), the optional org_name and project_name parameters provided in a tool call (search_issues, create_issue, update_issue) will be used as a fallback.

Note on Client Configuration: When configuring MCP clients like Claude code (see "Connecting MCP Clients" section), passing credentials or context via the client's --env flags effectively sets them as environment variables for the server process (Priority 2). This is the recommended way to provide explicit context in environments where Git detection might fail (like Windsurf or Cursor).

Running the Server

Once installed and configured, you can run the server using the command defined in pyproject.toml:

spacebridge-mcp-server

The server will start listening for MCP connections via standard input/output (stdio) by default.

Connecting MCP Clients

This server uses standard input/output (stdio) for communication. You need to configure your MCP client (e.g., Claude code, Windsurf, Cursor) to launch the spacebridge-mcp-server command and pass the required environment variables.

Configuration Steps:

  1. Install: Ensure spacebridge-mcp is installed (see Installation section). The spacebridge-mcp-server command should be available in your environment's path (e.g., inside your virtual environment's bin directory if installed from source, or globally if installed via pip install spacebridge-mcp).
  2. Find Server Path: Determine the full path to the spacebridge-mcp-server executable. If you installed in a virtual environment .venv, it might be /path/to/your/project/.venv/bin/spacebridge-mcp-server. If installed globally, you can often find it with which spacebridge-mcp-server (Linux/macOS) or where spacebridge-mcp-server (Windows).
  3. Add Server to Client: Use your MCP client's command for adding a new server.

Example using claude mcp add (Claude code):

claude mcp add spacebridge \
  /full/path/to/your/spacebridge-mcp-server \
  --scope user \
  --env SPACEBRIDGE_API_KEY="your-spacebridge-api-key" \
  --env OPENAI_API_KEY="your-openai-api-key" \
  • Replace /full/path/to/your/spacebridge-mcp-server with the actual path found in step 2.
  • Replace the placeholder API URL and keys with your actual credentials.
  • --scope user makes the server available across all your projects in Claude code. Use --scope project to limit it to the current project.

Other Clients (Windsurf, Cursor, etc.):

Refer to the specific documentation for your client. The general principle is the same: provide a name for the server and the command to execute it, ensuring the necessary environment variables (SPACEBRIDGE_API_KEY, OPENAI_API_KEY, and optionally SPACEBRIDGE_ORG_NAME, SPACEBRIDGE_PROJECT_NAME) are passed to the command's environment. Some clients might have dedicated fields for environment variables, while others might require a wrapper script. Passing SPACEBRIDGE_ORG_NAME and SPACEBRIDGE_PROJECT_NAME is recommended for clients where the server's working directory might not match the actual project directory (e.g., Windsurf, Cursor).

Usage Tips & Agentic Workflows

  • Automated Commit Messages: Configure your AI tool (e.g., via custom instructions or rules in Claude code, Windsurf, Cursor) to automatically reference relevant issue IDs when generating commit messages.
    • Example Rule/Instruction: "When generating a commit message, always ask the SpaceBridge-MCP tool to find or create an issue related to the changes and include the resulting issue ID (e.g., SB-123) in the commit message footer."
    • The AI can then use the search_issues or create_issue tool via this MCP server. If an issue exists, it gets the ID; if not, create_issue makes one and returns the new ID.
  • Context Augmentation: When asking your AI assistant to work on a feature or bug, provide the SpaceBridge issue ID. The assistant can then use the get_issue_by_id resource via this MCP server to fetch the full context (description, comments, status) directly from your tracker, leading to more informed code generation or analysis.
  • Quick Issue Creation: Simply ask your assistant "Create an issue about [brief description]" while coding. The create_issue tool will handle the similarity search and creation process.
