- Provides real-time web search results with source citations
- Compliant with MCP standard protocol
- Supports stdio transport
- Supports both Google AI Studio and Vertex AI

- Node.js 18 or later
- Google AI Studio API key (Get one here) or Google Cloud Project with Vertex AI enabled

It appears you're asking about the latest features in TypeScript. Here's a summary of recent updates and key features, based on the provided search results: Key Features in Recent TypeScript Updates:  Satisfies Operator: This operator lets you specify that a value conforms to a specific type without fully enforcing it.[1,2]  Const Type Parameters: Using const with type parameters provides more precision with function generics, helping specify literal types and prevent unwanted transformations.[2] This ensures arrays are treated as immutable, maintaining their literal types.[2]  Improved Enum Types: Enums are more robust, especially const enum, which optimizes enums by inlining their values at compile time.[2] From version 5.0, all enums are treated as a type union, even with calculated values.[1]  Template Literal Types: Template literal types are more expressive, allowing you to create types that build on literals, similar to JavaScript template strings.[2]  Unions and Intersections with Discriminated Unions: TypeScript offers better handling for union and intersection types, which are frequently used to build flexible types.[2] Discriminated unions allow you to create complex structures with ease and clear type guards.[2]  New ECMAScript Set Methods: Support for new methods like union, intersection, and difference for more powerful set operations.[3] TypeScript 5.8 Highlights (March 2025):  Module Node18 Flag: Provides a stable reference point for users fixed on Node.js 18, without incorporating certain behaviors of --module nodenext.[4]  Optimizations: Introduces optimizations that improve the time to build up a program and update it based on file changes, especially in --watch mode or editor scenarios.[4] This includes avoiding array allocations during path normalization.[4]  Import Assertions: --module nodenext in TypeScript 5.8 will issue an error if it encounters an import assertion, as Node.js 22 no longer accepts them using the assert syntax, recommending with instead.[4] Other Notable Features & Improvements:  Inferred Type Predicates: Improved type inference, especially with arrays and filtering.[3]  Control Flow Narrowing for Constant Indexed Accesses: Better type narrowing for accessing object properties.[3]  Regular Expression Syntax Checking: Basic syntax checks are performed on regular expressions, flagging errors like unclosed parentheses.[3]  Array filter Fixes: Properly filters the type of arrays when you use the filter function.  Object Key Inference Fixes: Improves type inference. Performance Enhancements:  Go Rewrite: A full rewrite of TypeScript in Go has been promised for version 7.0, which has demonstrated significant speed improvements (up to 10x-15x in some cases).[5] This will affect the compiler (tsc) and IDE performance (loading, hovers, errors, etc.).[5] The team chose Go for its structural similarity to the current JavaScript implementation.[5]  TypeScript 5.0: This update aimed to accelerate coding processes and simplify development by refining code, data structures, and streamlining import/export operations.[6] In summary, TypeScript is continuously evolving with new features and improvements aimed at enhancing developer productivity, code quality, and performance.[6] Sources: [1] edicomgroup.com (https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQFILdgh_4-Yh0OuwzDOqwCfvLGHdhm_PGhdAIzMK_DFwW38X9qK8b3Tj_ws2VZ2VLxWW_NJtuzot8B_wYYH4rOHBY_1HYZ7PyCHOCR3GzQpwQUi71ufAf6izU13O3W6GzjQAQnVjnheeRLLLf4mD7uueIS-g0yeivFo2XWZKJF4wtRtDfdTYjtHvRYmB7rY6Q==) [2] dev.to (https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQFFMJOcmJDu8TUJsc6cKjVMDTR7ggjQMUc1aMAIVKRhbTq7Zjzh5f_h-UpZn6LE6xB-nTqUmQwHCiUmhvAZ_uYmzXIzNmJvtoDUjDcB9hJDw_aPPvJjd411APwVfiNvd3yhlrB7MFsnxH25-hxNetmoZJrriZ0mGm6ZaYbm0yMeiruDqC5mnqXJwuyGLMdrg-M3LpRAGrxVAT9b1veE) [3] dev.to (https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQFfDcb-2QNwLZ0TpjSkNCWCvh-dvslYtllEMyyTXCSu-3jbOBD4vvq0j5Hqyuw8BcmEpKjBBeBZS83E-GCKax48hg5Oc1Fam6GQy296DxQkEQOfg7pvmnRhE3tdDbDCBqXKdYPonoR_AVLBAlGdKg==) [4] microsoft.com (https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQEWKA9uZsB7lcOGcnOLveyjImsqVwNItCj3n3QiCrCkyL6iY4rA16Wp37FecAoKgX58lcDcBOuXye97fgw5SAbLwDkl3M-vCUK0I0HxtCx8qMaBVM42sxyFEQjn1iz4Qgzud3P7pDlc4frHf6Wkgs8nNcoIlMriePVOb0l9vmY=) [5] totaltypescript.com (https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQFysE6zFlg_XiXfGqAiDapTIj2bsVWlkuq3Trpfacjd1a7gMDrUh35MKW-No9qdSKti68W3M2b1j6VqlnZ7v_yBOjE8hK_3d57U7UePyjMOUDdbBBGRK8CZeUug3hBOFsZjbnQoDdoL446oZL1R38gJrc9JvGmlWQno) [6] rabitsolutions.com (https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQEY1brKmgxI5YOA1HrB89SnHNPyhm3Dlz-zumJMoi-wBegLSOjto360JJrA29TwVB8A02qHWZBtwua0QHn8NxAjWUCCkLxD7lZa_xW4Mtp8diiAXl1ppIWEHq6T7B1Mm6_dMs3lWoOKOJSjCUrk6-P4ao40V-nYULfPtA==)
