# CommunityFix > CommunityFix is an open-source, community-driven platform where anyone can propose global challenges, submit solutions, and document real-world implementations as case studies. It combines collaborative problem-solving with a startup incubation model to turn ideas into sustainable ventures. The platform organizes knowledge as a tree: issues (problems) contain sub-issues and solutions; solutions contain case studies documenting where and how they were tried. Users can vote, endorse qualifications, and collaborate across disciplines. CommunityFix exposes an MCP (Model Context Protocol) server so AI assistants can search, browse, and contribute issues and solutions on behalf of authenticated users. ## Docs - [Whitepaper](https://communityfix.org/whitepaper): Vision, problem statement, incubation model, governance, and sustainability metrics - [Writing Guide](https://communityfix.org/guide/writing): How to write high-quality issues, solutions, and case studies - [MCP Server](https://communityfix.org/mcp): How to connect Claude Desktop, Claude Code, and other AI clients via the Model Context Protocol - [Privacy Policy](https://communityfix.org/privacy): Data handling and privacy practices - [Terms of Service](https://communityfix.org/terms): Platform terms and conditions ## API - [MCP Endpoint](https://communityfix.org/api/mcp): Model Context Protocol JSON-RPC endpoint for AI clients (OAuth 2.1 + PKCE required) ## MCP Tools - search_issues_solutions: Semantic vector search across all issues and solutions - get_issue: Fetch a single issue or solution by ID - get_tree: Get full tree of an issue with all descendants - create_issue: Create a new issue (top-level or sub-issue) - create_solution: Create a solution for an issue (requires parentId) - update_issue: Update an existing issue - update_solution: Update an existing solution - create_case_study: Document a real-world implementation of a solution - get_case_study: Fetch a case study by ID - list_case_studies: List all case studies for a solution - update_case_study: Modify a case study - suggest_more: Get semantically similar issues or solutions - search_tags: Search the tag taxonomy - get_user: Fetch a user profile - whoami: Get the authenticated user's profile ## Optional - [Source Code](https://github.com/mathix420/communityfix): Open-source Nuxt 4 codebase on GitHub - [Issue Catalog](https://communityfix.org): Browse and search global challenges and proposed solutions
