Domain knowledge for Fetter — workflow patterns, data models, and gotchas for your AI agent.
Fetter is a Python supply-chain security platform that helps monitor and validate Python package dependencies. It connects to the OSV (Open Source Vulnerabilities) database to provide real-time security intelligence about Python packages in your software supply chain.
Package Intelligence: Look up any Python package to see available versions, release information, and vulnerability status. Get detailed package metadata including version history and security advisories.
Vulnerability Detection: Check specific package versions against the OSV database to identify known security vulnerabilities. Receive detailed vulnerability reports including severity, affected versions, and remediation guidance.
Safe Version Discovery: Find the most recent version of any package that has no known vulnerabilities, helping you make informed decisions about package upgrades while maintaining security.
The service operates on Python packages identified by name and optional version specifiers (e.g., requests==2.31.0). Vulnerability data comes from the OSV database, which aggregates security advisories from multiple sources including PyPI, GitHub Security Advisories, and CVE databases.
Always use exact version specifiers when checking for vulnerabilities (e.g., requests==2.31.0 not requests>=2.0). The service requires precise version matching for accurate vulnerability assessment.
When seeking safe package versions, the service returns the latest available version with no known vulnerabilities, which may not always be the absolute latest version if recent releases have security issues.
This server uses the MCP protocol with a live tool list. Tools are discovered when your MCP client connects (often after authentication), so they are not enumerated on this public page. Open Studio or connect from your client to see the tools available to your workspace.
Python supply-chain security platform. Track installed packages and versions, monitor vulnerabilities via the OSV database, and validate against organization-wide allow lists. It provides MCP tools that your client discovers when it connects (this page may not list every tool name) that AI agents can use through the Model Context Protocol (MCP).
Add the MCPBundles server URL to your MCP client configuration (Claude Desktop, Cursor, VS Code, etc.). The URL format is: https://mcp.mcpbundles.com/bundle/fetter-mcp. Authentication is handled automatically.
Fetter is a remote MCP server. The live tool list is supplied by the server when your MCP client connects, so the count is not fixed on this public page. After you connect in MCPBundles Studio or your client, you will see the tools your session can call. A SKILL.md is still included to guide your agent on capabilities and workflows.
Fetter uses API Key. Fetter requires credentials. Connect via MCPBundles and authentication is handled automatically.
