What is the FOSSA (License Compliance) MCP Server?
Connect your FOSSA account to any AI agent to automate open-source license compliance and security auditing through natural language.
What you can do
- Project Overview — List all projects in your organization with support for filtering and pagination.
- Revision Tracking — Access specific project revisions and fetch detailed metadata for any version locator.
- Dependency Analysis — Deep-dive into the dependency tree of any revision to understand your software bill of materials (SBOM).
- Impact Assessment — Identify every parent project that contains a specific vulnerable or non-compliant dependency.
- Vulnerability Scanning — Check for security vulnerabilities across multiple dependency locators in a single query.
How it works
- Subscribe to this server
- Enter your FOSSA API Token
- Start auditing your software supply chain from Claude, Cursor, or any MCP client
Who is this for?
- Security Engineers — quickly identify where vulnerable packages are used across the entire organization.
- Legal & Compliance Teams — audit project revisions for license compliance without manually navigating the FOSSA UI.
- DevOps & Architects — verify dependency trees and project metadata directly from the terminal or code editor.

Frequently asked questions
Can I find which projects are affected by a specific vulnerable package?
Yes. Use the get_parent_projects tool with the dependency locator (e.g., npm+coa$2.0.2) to see every project in your organization that includes that specific dependency.
How do I check for security vulnerabilities in a list of dependencies?
You can use the check_vulnerabilities tool by providing an array of dependency locators. The agent will return any known security issues impacting those specific versions.
Can I see the full dependency list for a specific project version?
Absolutely. By using get_revision_dependencies with a revision locator, you can retrieve the complete list of dependencies identified by FOSSA for that specific build or release.
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.
