GXtract

GXtract implements the Model Context Protocol (MCP) server specification, enabling direct integration with VS Code and other MCP-compatible editors through a standardized bidirectional communication channel. The server exposes GroundX document understanding capabilities as MCP tools that editors can discover and invoke, handling serialization, request routing, and response marshaling between the editor client and GroundX backend services.

GXtract wraps GroundX platform's document understanding capabilities, translating MCP tool calls into authenticated API requests to GroundX backend services. The server handles API authentication, request formatting, response parsing, and error handling, exposing GroundX's document analysis features (extraction, classification, understanding) as callable tools with structured input/output schemas.

GXtract implements MCP tool discovery mechanism, dynamically exposing available GroundX document processing capabilities as discoverable tools with JSON Schema-defined input/output contracts. The server maintains a registry of available tools, their parameters, descriptions, and expected outputs, allowing editors to present these as autocomplete suggestions and validate user inputs against schemas before invocation.

GXtract manages GroundX API authentication lifecycle within the MCP server, handling credential storage, request signing, token refresh, and error handling for API calls. The server abstracts authentication complexity from the editor client, accepting tool invocations and transparently adding required authentication headers, managing API key rotation, and handling authentication failures with appropriate error responses.

GXtract implements comprehensive error handling for GroundX API failures, network issues, and malformed requests, translating backend errors into normalized MCP error responses with user-friendly messages. The server catches API exceptions, validates responses, handles timeouts, and provides structured error information that editors can display or log, preventing raw API errors from propagating to users.

GXtract enables chaining multiple document processing operations within editor workflows, allowing users to compose extraction, classification, and understanding operations sequentially or in parallel. The server maintains request context across multiple tool invocations, enabling workflows like 'extract data from document → classify extracted content → generate summary', with each step building on previous results.

GXtract extracts and enriches document metadata (creation date, author, language, document type, page count) using GroundX capabilities, providing structured metadata that can be used for document classification, filtering, and organization. The server parses GroundX metadata responses and normalizes them into consistent formats, enabling downstream tools to make decisions based on document properties.
