Overview

The hub-rest-api-python provides Python bindings for Hub REST API.

Paging and Black Duck v2022.2

In v2022.2 of Black Duck the REST API introduced a max page size to protect system resource usage. See the Black Duck release notes on Synopsys Community for the details of which API endpoints are affected. Users of the the python bindings here should leverage the Client interface which provides automatic paging support to make best use of these endpoints.

The old HubInstance interface and many of the examples using it do not perform paging and will break as a result of the changes in v2022.2.

Any issues related to the HubInstance Interface will be closed as Won't Fix

Any PRs with new or modified example scripts/utilities must use the client interface.

New in 1.0.0

Introducing the new Client class.

In order to provide a more robust long-term connection, faster performance, and an overall better experience a new Client class has been designed.

It is backed by a Requests session object. The user specifies a base URL, timeout, retries, proxies, and TLS verification upon initialization and these attributes are persisted across all requests.

At the REST API level, the Client class provides a consistent way to discover and traverse public resources, uses a generator to fetch all items using pagination, and automatically renews the bearer token.

See Client versus HubInstance Comparison and also read the Client User Guide on the Hub REST API Python Wiki.

Important Notes

The old HubInstance (in HubRestApi.py) keeps its existing functionality for backwards compatibility and therefore does not currently leverage any of the new features in the Client class.

We believe that the new features are compelling enough to strongly encourage users to consider moving from HubInstance to Client. See Client versus HubInstance Comparison.

Please give it a try and let us know what you think!

To use

from blackduck import Client
import logging
import os

logging.basicConfig(
    level=logging.INFO,
    format="[%(asctime)s] {%(module)s:%(lineno)d} %(levelname)s - %(message)s"
)

bd = Client(
    token=os.environ.get('blackduck_token'),
    base_url="https://your.blackduck.url",
    # verify=False  # TLS certificate verification
)

for project in bd.get_resource(name='projects'):
    print(project.get('name'))

Examples

Example code showing how to work with the new Client can be found in the examples/client folder.

Examples which use the old HubInstance interface -which is not maintained- are not guaranteed to work. Use at your own risk.

MCP Integration

The BlackDuck library now includes Model Context Protocol (MCP) support, enabling AI assistants to interact with BlackDuck Hub programmatically.

Installation with MCP Support

pip3 install blackduck[mcp]

Usage

1. Set Environment Variables

export BLACKDUCK_URL="https://your.blackduck.url"
export BLACKDUCK_TOKEN="your-api-token"

2. Start MCP Server

3. Configure MCP Client

For Claude Code, add to your MCP configuration:

{
  "mcpServers": {
    "blackduck": {
      "command": "blackduck",
      "args": ["--mcp"],
      "env": {
        "BLACKDUCK_URL": "https://your.blackduck.url",
        "BLACKDUCK_TOKEN": "your-api-token"
      }
    }
  }
}

Available MCP Tools

• list_projects - List BlackDuck projects
• get_project_details - Get project information
• list_project_versions - List project versions
• search_projects - Search projects by name
• get_project_vulnerabilities - Get security vulnerabilities
• list_project_components - List project components

See MCP_INTEGRATION.md for detailed documentation.

Version History

Including a version history on a go-forward basis.

v1.1.4 (Upcoming)

Added Model Context Protocol (MCP) integration:

• New blackduck --mcp CLI command to start MCP server
• Support for AI assistants via MCP tools
• Optional FastMCP dependency via pip install blackduck[mcp]
• Six core MCP tools for project and vulnerability management

v1.1.0

Retries will be attempted for all HTTP verbs, not just GET.

Test

Using pytest

git clone https://github.com/blackducksoftware/hub-rest-api-python.git
cd hub-rest-api-python
# optional but advisable: create/use virtualenv
# you should have 3.x+, e.g. Python 3.8.0+

pip3 install -r requirements.txt
pip3 install .
cd test
pytest

Install package locally

Do this when testing a new version.
