Frequently asked questions
How do I find my Contrast Security API credentials?
Log into your Contrast Security web interface. Navigate directly to your profile dropdown via User Settings -> Profile. Here you will find your distinct Authorization Key (encoded string), API Key, and the required Organization UUID at the very top.
What exactly is termed a 'Trace' in the Contrast ecosystem?
A Trace is the Contrast terminology applied to a single explicit instance of a security vulnerability uncovered deep within an executing application. Every trace holds a massive amount of payload data concerning the attack vectors.
Can I use this MCP integration to completely delete trace incidents?
No. The integration architecture focuses heavily on purely read-only auditing workflows. Features like permanently overwriting and deleting incident historical data are prohibited to ensure strong forensic compliance logs.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
