Implementation Reference
- src/index.ts:374-397 (handler)Main execution handler for the 'get_context' tool: extracts id and optional projectId from arguments, calls getContext, returns context content as text or throws error if not found.
case 'get_context': { const { id, projectId } = request.params.arguments as { id: string; projectId?: string; }; const context = await this.getContext(id, projectId); if (!context) { throw new McpError( ErrorCode.InvalidRequest, `Context not found with ID: ${id}` ); } return { content: [ { type: 'text', text: context.content, }, ], }; } - src/index.ts:250-267 (schema)Input schema and metadata definition for the 'get_context' tool, used in list tools response.
