CourseMCP: MCP server that indexes Canvas course content for AI agents
CourseMCP is a tool for students that indexes university course content (Canvas-hosted) so AI agents can query it without blowing up the context window. A Chrome extension ingests course materials in one click, and content is indexed at page/slide level using full-text and semantic strategies. LLMs consume the indexed content through an MCP-style interface for answering course-specific questions.

Bouncer: MCP proxy that blocks agents from sending data to untrusted destinations
Bouncer is a local MCP proxy that gates outbound tool calls from AI agents, denying calls to destinations derived from untrusted content (like web pages or emails) and allowing only explicitly trusted ones. It uses deterministic Python policy enforcement rather than an LLM in the enforcement path, preventing prompt-injection attacks that trick agents into leaking API keys or other sensitive data. It solves the problem of agents acting on malicious instructions embedded in untrusted content, protecting users and developers building agentic systems.
