Context7: Context7 is an MCP server that injects up-to-date, version-specific library documentation directly into LLM prompts. Add "use context7" to any coding prompt and it fetches current docs for the library you're working with, eliminating hallucinated APIs and outdated code examples. Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible editor.; trueline-mcp: trueline-mcp is an MCP plugin that provides hash-verified file editing and targeted reads for AI coding agents. It reduces context usage by reading less and writing less, and prevents silent code corruption by verifying that edits match the actual file content. It includes AST-based outlines, compact line-range edits, semantic diffs, and workflow hooks for high agent compliance.
