What is the GitGuardian MCP Server?
Connect your GitGuardian workspace to any AI agent to strengthen your security posture and manage secret leaks through natural conversation.
What you can do
- Incident Management — List, retrieve, and resolve secret incidents. Assign team members to leaks and track remediation progress.
- Honeytokens — Create and manage decoy credentials (honeytokens) to detect unauthorized access to your private infrastructure.
- Security Scanning — Scan code snippets or content for secrets and sensitive data in real-time to prevent leaks before they happen.
- Audit & Compliance — Access detailed audit logs to monitor workspace activity and ensure compliance with security policies.
- Team Collaboration — Manage teams, members, and API tokens to orchestrate security operations across your organization.
How it works
- Subscribe to this server
- Enter your GitGuardian API Key
- Start monitoring and securing your code from Claude, Cursor, or any MCP-compatible client
Your AI acts as a 24/7 Security Operations Center (SOC) assistant, helping you triage alerts and deploy defenses without leaving your workflow.
Who is this for?
- Security Engineers — quickly triage secret incidents and manage honeytoken deployments across multiple environments.
- DevOps & SREs — automate security audits and monitor workspace health checks directly from the terminal or IDE.
- Developers — scan code for secrets before committing and check incident statuses without switching to the GitGuardian dashboard.

How Vinkius secures
GitGuardian for LangChain
Every tool call from LangChain to the GitGuardian MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I resolve a secret incident directly through the AI?
Yes. You can use the resolve_secret_incident tool by providing the incident ID. You can also use assign_secret_incident to delegate the fix to a specific team member.
How do I create a decoy credential to catch attackers?
Use the create_honeytoken tool. You can specify the type and name of the honeytoken, and GitGuardian will generate a decoy that alerts you if it's ever used.
Is it possible to scan a text block for secrets before I commit it?
Absolutely. Use the scan_content tool. Provide the document content and a filename, and the AI will return any detected secrets or policy violations found by GitGuardian's engine.
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.
